The project, “Monitoring of Mobile Estuarine Organisms at Restored Oyster Reefs,” focuses on tracking fish, crabs, snails, and other aquatic species that call these reefs home, as well as using cutting-edge environmental DNA (eDNA) techniques to detect organisms that might otherwise go unnoticed. As a consultant to AKRF, our team deployed collection gear across current and potential restoration sites, including Brooklyn Bridge Park, Bush Terminal Park, Flushing Bay, and Paedergat Basin. The sampling enclosures, left in the water for 48 hours, revealed a fascinating snapshot of estuarine life, from small schooling fish to a surprise dogfish, a small shark-like species that was one of the highlights of the summer survey sessions. This collaborative initiative brings together multiple partners: Billion Oyster Project, the driving force behind large-scale oyster reef restoration in New York Harbor, is leading the project. AKRF, headquartered in New York City, is serving as the primary consultant; Princeton Hydro is leading the mobile estuarine sampling efforts and eDNA sample collection; and Monmouth University is analyzing the eDNA samples to help identify species present at the restoration sites. Oyster reefs are living structures that provide essential habitat for a wide array of species, improve water quality through natural filtration capabilities, and enhance the resilience of New York Harbor against coastal storms and erosion. Monitoring oyster reefs ensures that restoration efforts are successful and helps scientists refine approaches for scaling up oyster reef projects in urban estuaries locally and throughout the world. As the field sampling lead, Princeton Hydro completed two monitoring and sampling collection events, one this Spring and one this Summer, at the various oyster reef restoration sites. Using sea bass and minnow collection gear, our team - Jesse Smith, Aquatic Ecologist; Jackson Tilves, Staff Scientist; and Kaitlyn Jones, Staff Scientist - identified, measured, and documented each of the found species before safely returning them to the water. In addition, we collected in-situ water quality data at each site to help interpret how environmental conditions influence reef communities. [caption id="attachment_18273" align="aligncenter" width="1227"] Jackson and Jesse preparing to deploy sampling collection gear in Brooklyn Bridge Park.[/caption] [gallery columns="2" link="none" size="medium" ids="18274,18267"] Our team brings deep experience and specialized equipment to this project. Princeton Hydro’s biologists have conducted estuarine surveys throughout the Hudson River and New York Harbor, led nekton and benthic sampling along New Jersey’s coastline, and carried out numerous studies that inform restoration and resilience efforts across the region. Alongside traditional monitoring, the “Monitoring of Mobile Estuarine Organisms at Restored Oyster Reefs” project uniquely incorporates eDNA sampling. eDNA is genetic material that organisms shed into their surrounding environment, through skin cells, mucus, or waste, that can be detected in water samples. By collecting and analyzing eDNA, scientists can identify the presence of species that may not appear in sampling enclosures. The analysis provided by the team at Monmouth University helps paint a fuller picture of biodiversity at the restored oyster reef sampling locations. More Scenes from the Field The photos below capture moments from the field and the diverse aquatic life our team encountered, offering a glimpse into the many species that oyster reefs help support in the New York Harbor: [gallery link="none" size="medium" ids="18276,18271,18277,18272,18269,18284"] *The Asian Shore Crab pictured above is an invasive species encountered fairly often during the Summer sampling events.

Yet the performance and longevity of these structures depend just as much on the subsurface conditions beneath them. Geotechnical engineering is the discipline dedicated to investigating, analyzing, and characterizing soil, rock, landscape, and groundwater conditions, and applying that data to the design and construction of safe, resilient, and sustainable infrastructure and restoration projects. At Princeton Hydro, our geotechnical and soils engineers design and execute customized, cost-effective investigations that provide the parameters needed for successful design. Because geotechnical services touch every stage of a project, our integrated approach of investigation, including soils laboratory testing, analysis, and design, all done in-house, ensures streamlined communication, efficiency, and technical excellence. This blog offers a closer look at what geotechnical engineering entails, the specialized capabilities Princeton Hydro provides, and real-world examples of how our work supports resilient, sustainable design. Princeton Hydro’s Geotechnical Capabilities Geotechnical Investigations: Our engineers can perform subsurface investigation, identification, and assessment of accumulated sediment, subsurface soils, and rock, as well as slope stability and stabilization modeling. Our work ranges from foundation type and bearing capacity assessments to mitigation strategies for unsuitable materials. We also regularly conduct forensic geotechnical investigations, which focus on investigating soil-interaction-related failures of engineered infrastructure. Laboratory Testing: We operate an American Association of State Highway and Transportation Officials (AASHTO) Accredited laboratory in Sicklerville, NJ. This allows us to complete 100% of geotechnical investigation planning and oversight, laboratory testing, analysis, design, and reporting in-house. Our geotechnical laboratory performs a full suite of soils and materials testing, including grain size analysis, plasticity index, organic content, moisture content, compaction characteristics of soil (Standard and Modified Proctor), California bearing ratio (CBR), one dimensional consolidation, and flexible and rigid wall permeability testing under constant or falling head conditions. With this capability, we can rapidly deliver high-quality data to inform project design and construction. Our laboratory is also a U.S. Army Corps of Engineers (USACE) Validated Laboratory. Click here to view Princeton Hydro’s complete accreditation listing and certificate. And, click here to learn more about the USACE Materials Testing Laboratories and Validation. Field & Construction Services: Our engineers are experienced in construction requirements, design, and methodology for various structures, as well as field inspections and special testing. We have a Certified Construction Specifier (CCS) on staff and ACI-certified concrete field-testing technicians. Our team performs compaction testing of soil and asphalt using a nuclear density gauge, reinforcing steel inspections, and 2006 International Building Code (IBC) special inspections. We help determine foundation type, site improvements, and optimal construction techniques. Dredging & Sediment Investigations: Over our 25-year history, we’ve managed more than 100 dredging projects across freshwater and estuarine systems. We specialize in beneficial reuse of dredged material for ecological restoration, including wetland creation, thin-layer placement, and living shorelines. Our team provides sediment characterization, slope stability modeling, and contaminant analysis in complex, developed watersheds. Princeton Hydro’s Geotechnical Work in Action To bring this work to life, we’ve chosen a few Princeton Hydro projects that showcase where our geotechnical expertise helped solve unique challenges: Geotechnical Design & Subsurface Investigations for Coastal Wetland Restoration – New York At Spring Creek Park North in Jamaica Bay, New York, decades of urbanization and dredged material placement had degraded more than 40 acres of tidal marsh and uplands. To address this, Princeton Hydro provided subsurface investigations and design services for a large-scale ecosystem restoration led by the USACE New York District, in partnership with NYC Parks. A key design assumption was the reuse of excavated material: soils removed from wetland areas were repurposed to construct upland hills, supporting both ecological function and cost-effective implementation. Our work included geotechnical borings, slope stability analyses, and hydraulic modeling, as well as the collection of topographic and bathymetric survey data, wetland delineations, vegetation assessments, and hydrodynamic measurements. This data informed the development of slope stability and hydraulic models and guided the restoration design. The project advanced through a structured engineering design process — with 30%, 60%, 90%, and 100% design submissions — along with preparation of technical specifications, permit applications, and a detailed construction cost estimate. When complete, the project will restore more than 43 acres of marsh and upland habitat, improving water quality, enhancing biodiversity, and strengthening climate resilience in one of New York City’s most ecologically significant coastal systems. [gallery size="medium" link="none" columns="2" ids="18187,18188"] Offshore Subsurface Investigation for Jetty Reconstruction – Delaware Princeton Hydro was contracted by USACE Philadelphia District to perform offshore subsurface geotechnical investigations in support of reconstructing the Indian River Inlet jetty at Delaware Seashore State Park. Working under challenging marine conditions, our team successfully advanced deep geotechnical borings (to depths of 100 feet) from a lift boat platform, collected soil samples, performed laboratory testing including triaxial strength, consolidation, and direct shear tests; and delivered detailed soil data. Despite difficult sea states, we maintained close communication with USACE to ensure safety and project continuity. The resulting data provided USACE with critical insight into subsurface conditions, helping inform design alternatives for the new jetty structure. [gallery size="medium" columns="2" link="none" ids="18185,18184"] Subsurface Investigations for Dike Raising – New Jersey At the Killcohook Confined Disposal Facility (CDF), Princeton Hydro carried out a large-scale subsurface investigation to support USACE Philadelphia District’s plans for raising the site’s perimeter dikes. The project site, formerly a National Wildlife Refuge, is located in Pennsville, New Jersey, on the eastern bank of the Delaware River, to the north of Fort Mott State Park and adjacent to the Supawna Meadows Wildlife Refuge. Each cell of the CDF receives dredge material from the Delaware River. The subsurface explorations performed by Princeton Hydro were conducted along the existing dike comprising the border of Cell 1 of the CDF. Cell 1 consists of an area of approximately 710 acres with the entire CDF covering 1,200 acres. For this exploration project, Princeton Hydro was tasked with the performance of thirty-one (31) geotechnical borings as well as sixty-five (65) cone penetrometer tests with porewater measurements (CPTu) soundings. Princeton Hydro also provided site safety oversight in accordance with USACE standards. Soil samples were logged and collected by Princeton Hydro and tested at their Sicklerville, New Jersey geotechnical laboratory, which is accredited under the AASHTO Accreditation Program and validated by USACE for soils testing. The data collected is now being used by USACE to design the upgraded dike system, ensuring safe, resilient operation of the facility for future dredged material management. [gallery link="none" columns="2" size="medium" ids="18181,18183"] Comprehensive Geotechnical Investigation and Reporting – New Jersey At the 545-acre Pedricktown North Confined Disposal Facility in Oldmans Township, New Jersey, located on the Delaware River west of Route 130 between Porcupine Road and Pennsgrove-Pedricktown Road, Princeton Hydro conducted a comprehensive subsurface investigation in support of a dike raising project led by the USACE Philadelphia District. As part of this field exploration, our team performed eight geotechnical borings, thirty-eight cone penetrometer tests with porewater measurement (CPTu) soundings, and collected five grab samples. These efforts provided critical soil strength and settlement data to inform USACE’s design of the upgraded dike system. In addition to managing subcontractors and ensuring compliance with USACE safety protocols, Princeton Hydro oversaw the field program, coordinated directly with the Project Manager, and delivered the final geotechnical report. This investigation is supplying USACE with essential geotechnical data to guide the design and construction of the improved dike infrastructure.

At the same time, these landscapes provide critical habitat and natural defenses that protect people, ecosystems and myriad wildlife. Coastal ecological restoration restores natural systems and strengthens future resilience to climate impacts. Earlier this month, our team joined the New Jersey Coastal Resilience Collaborative (NJCRC) for its Coastal Ecological Restoration Technical Workshop, a full-day, in-person event held at the Rutgers EcoComplex in Bordentown, NJ. The workshop convened coastal stakeholders, researchers, practitioners, and managers to share knowledge and explore the latest science advancing coastal ecological restoration. Inside the Workshop The day began with a work group session, “Advancing Science-Based Ecological Restoration Across New Jersey’s Coast,” led by a panel of experts and followed by an interactive Q&A. Click here to view the presentation. Participants then chose from a variety of technical sessions covering topics such as, eDNA and Water Quality as Indicators of Coastal Ecological Health; Smart Permitting for Restoration; and Diatoms as Ecological Indicators in Living Shoreline Applications. Dana Patterson Grear, Princeton Hydro's Director of Marketing & Communications, delivered an engaging presentation titled, "How to Build a Digital Communications Toolkit for Climate Action." She provided practical guidance for turning communication into a powerful tool for advancing ecological restoration and climate resilience, including how to develop tailored climate messaging, understand the values of your audience and remove personal bias, and determine your level of engagement and capacity. Dana's presentation broke down complex communication strategies into actional steps that attendees can apply directly to their work. Click here to view her presentation slides.

And, as a fun and fitting bonus, each participant went home with a complimentary native plant courtesy of Pinelands Nursery. More About Coastal Restoration Coastal ecological restoration involves the rehabilitation and creation of coastal ecosystems, like wetlands, reefs, and shorelines, with the goal of restoring the natural processes and functions. These efforts provide long-term protection from erosion, create habitat for fish and wildlife, and build community resilience against flooding and storm surge. At Princeton Hydro, we understand the impacts of climate change, including sea level rise, and use tools such as vulnerability assessments to inform our restoration designs. Our team specializes in designing and implementing living shorelines and habitat restoration projects. We combine field data, empirical approaches, ecological and geomorphic understanding, hydrologic and hydraulic modeling, and state-of-the-art computer programming technology to develop our designs. Our nature-based solutions deliver lasting ecological and community benefits. A prime example of this work is the Spring Creek North Ecosystem Restoration project, located in Brooklyn and Queens, NY. Once part of the expansive Jamaica Bay wetland system, Spring Creek's salt marshes were heavily degraded over the last century. Princeton Hydro was contracted by the U.S. Army Corps of Engineers, New York District to lead the design and engineering for this restoration effort. Construction efforts began in early October 2025. Once completed, the project will restore approximately 43 acres of habitat within a 67-acre footprint, including low and high marsh, scrub shrub wetland, and maritime upland. Efforts also aim to improve water quality, increase biodiversity, and strengthen the overall Jamaica Bay ecosystem. Key restoration activities include:

The day began with a work group session, “Advancing Science-Based Ecological Restoration Across New Jersey’s Coast,” led by a panel of experts and followed by an interactive Q&A. Click here to view the presentation. Participants then chose from a variety of technical sessions covering topics such as, eDNA and Water Quality as Indicators of Coastal Ecological Health; Smart Permitting for Restoration; and Diatoms as Ecological Indicators in Living Shoreline Applications.
Dana Patterson Grear, Princeton Hydro's Director of Marketing & Communications, delivered an engaging presentation titled, "How to Build a Digital Communications Toolkit for Climate Action." She provided practical guidance for turning communication into a powerful tool for advancing ecological restoration and climate resilience, including how to develop tailored climate messaging, understand the values of your audience and remove personal bias, and determine your level of engagement and capacity. Dana's presentation broke down complex communication strategies into actional steps that attendees can apply directly to their work. Click here to view her presentation slides.
Beyond the educational workshops, networking breaks, shared meals, and a post-workshop reception created opportunities to connect and collaborate. And, as a fun and fitting bonus, each participant went home with a complimentary native plant courtesy of Pinelands Nursery.
Coastal ecological restoration involves the rehabilitation and creation of coastal ecosystems, like wetlands, reefs, and shorelines, with the goal of restoring the natural processes and functions. These efforts provide long-term protection from erosion, create habitat for fish and wildlife, and build community resilience against flooding and storm surge.
At Princeton Hydro, we understand the impacts of climate change, including sea level rise, and use tools such as vulnerability assessments to inform our restoration designs. Our team specializes in designing and implementing living shorelines and habitat restoration projects. We combine field data, empirical approaches, ecological and geomorphic understanding, hydrologic and hydraulic modeling, and state-of-the-art computer programming technology to develop our designs. Our nature-based solutions deliver lasting ecological and community benefits.
A prime example of this work is the Spring Creek North Ecosystem Restoration project, located in Brooklyn and Queens, NY. Once part of the expansive Jamaica Bay wetland system, Spring Creek's salt marshes were heavily degraded over the last century. Princeton Hydro was contracted by the U.S. Army Corps of Engineers, New York District to lead the design and engineering for this restoration effort. Construction efforts began in early October 2025. Once completed, the project will restore approximately 43 acres of habitat within a 67-acre footprint, including low and high marsh, scrub shrub wetland, and maritime upland. Efforts also aim to improve water quality, increase biodiversity, and strengthen the overall Jamaica Bay ecosystem.
The following photos depict the degraded habitat and pre-construction conditions of the site. Stay tuned to our blog for more photos from each of the project phases.

The Winchell-Smith Dam on the Farmington River in Connecticut has been removed! This long-anticipated project, spearheaded by the Farmington River Watershed Association (FRWA), is a major milestone in the restoration of the Farmington River. The full removal and restoration effort, which began on September 8, reconnects 30 miles of critical upstream habitat.
The effort is the result of a robust collaboration among project partners, following years of persistence and careful planning to turn a long-standing vision for the Farmington River into reality. Under the leadership of FRWA, the project partners include Miss Porter's School, the current dam owner; Princeton Hydro, providing engineering, design and project oversight; RiverLogic Solutions; CTDEEP Fisheries; and the Town of Farmington. Together, these partners are advancing ecological restoration, community safety, and recreation access along one of New England's most celebrated rivers.
The Farmington River, a designated "Partnership Wild & Scenic River," flows for nearly 47 miles along its main stem in northwest Connecticut, with major tributaries extending into southwest Massachusetts. It's longest route, originating from the West Branch, stretches 80.4 miles, making it the longest tributary of the Connecticut River. Its watershed spans more than 600 square miles, providing critical drinking water to hundreds of thousands of people, supporting a world-class trout fishery, and serving as a vital habitat for a variety of resident and migratory species. Nearly 79 miles of the river are federally protected for their outstanding natural, cultural, and recreational values.
The Winchell-Smith Dam, a 200-foot-wide, 4-foot-high, low-head timber crib structure, dates back to the early 1600s and may have been the first gristmill ever built on the Farmington River. The dam had long ceased to serve a functional purpose but continued to impede the river's natural process, blocked access for migratory fish, created localized erosion and scour, presented an obstacle for paddlers and anglers, and posed as a safety hazard.
Removing the dam delivers myriad benefits to the ecological landscape and surrounding community. Most significantly, it reopens 30 miles of historic spawning habitat for species such as American shad, alewife, blueback herring, sea lamprey, and American eel, and provides unobstructed access to the upper reaches of the river and its tributaries. The restored river channel will support healthier fish populations, stabilize riverbanks, reestablish important wildlife habitat, and improve water quality. Additionally, the project enhances public safety by eliminating a hazardous low-head dam and expands opportunities for nature-based recreation along this cherished waterway.
The photos below, taken by Princeton Hydro Senior Fluvial Geomorphologist Casey Clapsaddle, show the rapid progress being made at the Winchell-Smith Dam site:
Princeton Hydro's involvement at the Winchell-Smith Dam site dates back to 2009, when the engineering team worked with FRWA to complete early assessments and developed a design for a nature-like fishway. Funding constraints and the dam's continued deterioration ultimately made full removal the only viable option. With funding support from CTDEEP Fisheries, the effort to fully remove Winchell-Smith Dam was finally able to advance.
Princeton Hydro provided comprehensive engineering services, including site investigation and geomorphic inspection, wetland delineation, hydrologic assessment and hydraulic modeling, permitting, and construction oversight.
The removal of the Winchell-Smith Dam is part of a larger restoration plan initiated by FRWA and Princeton Hydro, which included the removal of the Spoonville Dam. The 35-foot-high concreate dam once stood as the first barrier to fish passage on the Farmington River.
While the Winchell-Smith Dam itself is being dismantled, its history will not be lost. Timbers from the structure are being preserved and repurposed for educational objectives, honoring the site's industrial legacy while celebrating its ecological renewal. Rocks and boulders from the dam will also be used to restore the river location, constructing a riffle-like condition in the riverbed.
The project also aims to foster the next generation of environmental stewards by engaging the students at Miss Porter's School and local public schools. Throughout the process, students are participating in hands-on activities that deepen their understanding of river restoration and introduce them to STEM subjects like engineering and ecology.
As demolition progresses, partners, community members, and environmental advocates are celebrating the return of a free-flowing Farmington River and looking forward to its continued transformation. Stay tuned to for more updates!

Welcome to our “A Day in the Life” blog series, where we explore the diverse expertise and everyday experiences of the professionals who power Princeton Hydro’s mission. In this edition, we feature Nicole Hanson, Office and Special Projects Manager, and delve into her role as Health & Safety Program Lead.
While you may spot many of Princeton Hydro’s team members out in the field inspecting dams, delineating wetlands, or monitoring water quality, Nicole’s work happens mostly behind the scenes. Her dedication to health and safety makes all those field activities possible. Spend a day with her, and you’ll quickly see that safety is anything but routine. It’s equal parts organization, problem-solving, collaboration, and people-care (with a healthy dose of coffee).
Nicole joined Princeton Hydro in 2007, starting in the former Voorhees, NJ office with administrative tasks like answering phones, ordering supplies, and organizing files. Before long, she took on a much larger responsibility: helping coordinate the construction of Princeton Hydro’s Southern Regional Office in Sicklerville, NJ. The new space was designed to accommodate the firm’s growing staff and house the Geotechnical Soils Testing Laboratory, a facility accredited by the American Association of State Highway and Transportation Officials (AASHTO) and validated by the U.S. Army Corps of Engineers (USACE) Materials Testing Center (MTC) to perform a full range of tests.
“The office construction project was my first taste of special projects management,” Nicole reflects. “From pouring concrete, coordinating with the movers to relocate the entire office to the new office, and working with the team installing furniture, I was involved in almost every detail. I still have all the original documents and notes from that time.”
Over the years, inspired by the many women in leadership roles at Princeton Hydro, Nicole worked hard to grow into her own influential path. "Working alongside such talented and dedicated women showed me what leadership looks like in action, and motivated me to grow, learn, take on new challenges every day, and pursue my own professional goals."
Today, alongside her Office Management and Special Projects responsibilities, Nicole manages Princeton Hydro’s Health & Safety Program in partnership with Chief Operating Officer Megan Hunter Ruff and Regional Safety Leaders (RSLs) Jerry Vogel, Chris Mikolajczyk, CLM, and Casey Pantaleo, PE. She has been instrumental in formalizing and advancing the program’s systems and practices. "I take great pride in knowing that I play a key role in implementing a Health & Safety Program that protects our employees in their specific line of work and ensures that everyone goes home safely."
Nicole’s day begins at 8:00 AM, caramel iced latte in hand. After scanning her inbox and calendar, she sets her priorities for the day, though she knows her plan may shift at any moment.
“I’m constantly juggling tasks, solving problems, and adapting on the fly,” Nicole says with a laugh. “What surprises people most is how unpredictable my day can be, and how many different team members I connect with across projects. Some mornings, I’ll talk to fifteen employees before I even drink my second cup of coffee!” One moment Nicole is coordinating health and safety needs, the next she’s ordering lunch for the team, and later she’s assisting with a proposal submission. No two hours, let alone two days, look the same!
Interwoven with the many tasks on Nicole’s to-do list each day are her health and safety responsibilities, which she views as mission critical. She creates “Toolbox Talks” and newsletter updates on various health and safety topics, verifies all staff certifications are valid and current, reminds staff of required safety trainings, and works with team members to order specific Personal Protective Equipment (PPE), including safety vests, masks, hard hats, and other field gear. Nicole also keeps the Health & Safety Program current by reading safety-industry publications and attending virtual OSHA-regulated training courses, ensuring both the company protocols and her own knowledge evolve with the latest standards. Her role centers on coordinating and administering the program logistics, compliance tracking, and staff resources, rather than acting as a certified technical safety professional.
Success, she says, comes down to collaboration, flexibility, and attention to detail. “Honestly, no one has it all figured out. My role is constantly evolving, so I rely on my notebook to track tasks and stay organized. I’m always open to feedback and enjoy learning from those around me - teamwork is everything, and a steady supply of coffee doesn’t hurt either!”
Nicole’s role is unique in that she bridges multiple departments and disciplines within Princeton Hydro. As Health & Safety Program Lead, she works closely with the COO, RSLs, and many other technical staff across the company, a collaboration ensures that while Nicole steers the day-to-day systems, the technical experts remain at the core of the program's success.
Nicole takes immense pride in Princeton Hydro's comprehensive Health & Safety Program. “It became my baby,” she says. “Safety doesn’t always get the spotlight, but it’s essential and the backbone of everything we do here at Princeton Hydro. Every time I help someone navigate a challenge or ensure they have the right tools and support, I know I’m contributing to both their success and their safety, and that feels great!"
Nicole puts a lot of effort into making sure staff are prepared and equipped to handle the unique risks of environmental engineering and in-the-field science. Maintaining a strong Health & Safety Program at Princeton Hydro involves a lot of research, planning, budgeting, and communication, including:
Beyond the checklists and compliance requirements, Nicole also looks for creative ways to keep safety top of mind. By creating and sharing safety-themed memes, she makes important reminders easier to remember and a lot more fun. Here are a few of our favorites:
For special projects, risk assessment and mitigation start on day one. Nicole reviews project goals, timelines, and team roles with a critical eye, helping to identify potential challenges, whether logistical, regulatory, or health and safety related. By asking questions and gathering input from both field staff and managers, she zeroes in on the right Health & Safety experts to guide the team and flags anything that could derail success.
For Nicole, every challenge is also an opportunity. She welcomes the twists and turns that come with her work, letting new projects and unexpected needs guide her growth. “There’s always something new to learn or take on, and I’ve learned to stay open to wherever the day leads me."
After 18 years with Princeton Hydro, Nicole continues to approach her role with curiosity and momentum. She is committed to refining and expanding the Health & Safety Program, not by resting on what already works, but by seeking out new opportunities to make systems more efficient, accessible, and effective. She welcomes input from colleagues and pairs it with her own creative problem-solving to build tools that support the entire team.
Looking ahead, one of Nicole’s top priorities is creating a centralized internal platform that gives staff easy access to safety resources, training reminders, Active AHAs, and comprehensive program documents, whether they’re in the office or out in the field. To bring this vision to life, she’s collaborating closely with the COO and RSLs, combining operational insight with technical safety expertise to build a system that’s both practical and comprehensive for the entire company.
At the end of the day, Nicole’s goal is simple: give her colleagues the confidence to do their best work, backed by the training, tools, and systems that keep them safe. “My highest priority is ensuring that every employee returns home safely to their loved ones at the end of each day. Nothing I do is more important than protecting the health and well-being of our team.”

Princeton Hydro's Director of Aquatics, Michael Hartshorne, recently traveled to Pietermaritzburg, South Africa, to present at the Southern African Society for Aquatic Scientists (SASAqS) Congress 2025. Hosted by the Institute of Natural Resources (INS) and the University of KwaZulu-Natal, the annual event convened researchers, industry professionals, government officials, and students from around the world to advance aquatic science by linking research with real-world practice.
Over the course of five days, participants shared insights on critical global and regional issues, including water pollution, water security, biodiversity conservation, climate change adaptation, and community-based resource management. The program featured an array of interdisciplinary presentations spanning hydrology, freshwater ecology, and policy, while also creating space for collaboration and connection through interactive workshops, poster sessions and exhibits, networking events, and a gala dinner and awards ceremony. On the closing day, field trips brought attendees out into the surrounding landscape, offering a tangible backdrop to the themes explored throughout the conference.
On the opening day of the SASAqS Congress 2025 program, Michael addressed the full conference audience with a presentation titled “Novel Techniques for the Monitoring of Harmful Algal Blooms (HABs) in Lakes and Rivers of the United States,” which focused on innovative approaches for detecting and managing HABs, a growing worldwide concern driven by nutrient pollution and climate change. Michael illustrated how innovative research can inform practical management strategies while encouraging global collaboration.
HABs are intensifying in frequency, scale, and severity worldwide, presenting challenges for drinking water supplies, recreational lakes, and river ecosystems. Michael’s presentation showcased a suite of monitoring tools, from handheld phycocyanin and phycoerythrin meters, to drones with multispectral lenses, to advanced techniques such as qPCR (quantitative Polymerase Chain Reaction), microscopy, and akinete cell monitoring. Through case studies from lakes, reservoirs, and river systems in New Jersey, Virginia, and Pennsylvania, he highlighted the strengths and limitations of each method, emphasizing the importance of tailoring monitoring strategies to the unique conditions of each waterbody. Michael also discussed management interventions and highlighted how emerging technologies can support more adaptive, science-driven management of HABs.
“It was an honor to participate in this year’s event and learn alongside so many dedicated professionals who are working to protect and restore aquatic ecosystems,” said Michael. “The international exchange of ideas and techniques is critical in helping us all address the increasingly complex challenges facing our water resources.”
The conference concluded with optional field trips that gave participants a chance to view South Africa’s aquatic systems and management challenges firsthand. Each excursion highlighted a different aspect of aquatic science in practice:
UKZN Zebrafish Research Facility: On the University of KwaZulu-Natal’s Pietermaritzburg campus, this outing introduced participants to the zebrafish as a model organism for studying genetics, development, and aquatic toxicology. The tour provided a window into laboratory-based aquatic science and its applications to regional and global challenges.
Lions River Monitoring Demonstration: Hosted by GroundTruth, this field trip took a group to Lions River to observe live demonstrations of water quality and quantity monitoring using advanced tools such as UAVs (drones), USVs (unmanned survey boats), and a suite of citizen science methods, including MiniSASS, clarity tubes, and velocity planks. The excursion showcased how high-tech innovation and community-driven monitoring can complement one another in managing freshwater resources.
Outside of the conference, Michael took the opportunity to explore the diverse beauty and culture of South Africa. At Betty's Bay, a small town on the Western Cape he enjoyed coffee while taking in sweeping coastal views; walked scenic trails; spotted a few Hyraxes and Chacma baboons; and observed the African penguin (Spheniscus demersus) at the Stony Point colony. He also viewed the Cape Rockjumper (Chaetops frenatus), a ground-dwelling bird endemic to the mountain Fynbos, at nearby Rooi-Els.
He visited Karkloof Nature Reserve in the KwaZulu-Natal province, a rural agricultural area which has implemented conservation efforts for the once endangered, but still threated, Wattled Crane (Grus carunculate).
Michael’s participation in SASAqS Congress 2025 reflects Princeton Hydro’s ongoing commitment to advancing aquatic science and collaborating with experts around the world. By sharing practical monitoring and management strategies for HABs, his contributions added to a rich global dialogue on how science can inform sustainable solutions.

Welcome to our Partner Spotlight blog series, where we highlight the meaningful collaborations and shared successes Princeton Hydro enjoys with our valued partners. Today, we’re shining the spotlight on Save Barnegat Bay, a nonprofit rooted deeply in environmental advocacy and stewardship, dedicated to safeguarding Barnegat Bay.
Fed by freshwater inputs from rivers, creeks, and streams, and saltwater from the Atlantic Ocean, Barnegat Bay is a unique estuary stretching approximately 42 miles from Bay Head to Long Beach Island and the Little Egg Harbor inlet. Barnegat Bay is the largest body of water in New Jersey and one of the region’s most valuable natural resources.
Save Barnegat Bay, founded in 1971 by neighbors concerned about the future of their local waterways, has grown into a highly respected, effective, and influential voice for environmental protection throughout the state. Through advocacy, education, restoration, and community engagement, the organization is leading the charge to preserve the Barnegat Bay ecosystem and the wildlife and communities that call it home.
For this Partner Spotlight, we spoke with Britta Forsberg, Executive Director of Save Barnegat Bay, who brings decades of personal and professional commitment to protecting this vital resource.
Let’s jump in!
“What truly sets Save Barnegat Bay apart is our hyper-local approach. We’re not a Washington, D.C.-based environmental group, we’re right here in the Barnegat Bay Watershed, working directly with the communities we serve. For 54 years, we’ve remained a steady and effective environmental voice, and we’ve achieved meaningful, lasting impacts through persistence, collaboration, and grassroots engagement.”
In the video below, Britta shares more about the guiding vision behind Save Barnegat Bay’s work and what continues to fuel the organization’s success:
“Save Barnegat Bay’s work spans decades and addresses a wide range of threats to the watershed, from nutrient pollution to legacy contamination. One of our most impactful successes is the passage of the New Jersey Fertilizer Law, which we wrote and lobbied for. It remains the strictest fertilizer content law in the country. This effort began with local ordinances, but we quickly realized a patchwork of municipal laws wasn’t effective. So, we pursued statewide legislation to reduce nitrogen pollution, a major stressor for Barnegat Bay’s ecological health. This law has helped prevent millions of tons of nitrogen from entering New Jersey’s waterways.
Another critical focus for us is environmental justice and accountability. We’re currently challenging a controversial settlement related to the Ciba-Geigy Superfund Site in Toms River. This site has a painful history: decades ago, a chemical plant discharged toxic waste into rivers, groundwater, and even the Atlantic Ocean, resulting in significant health impacts, including a well-documented childhood cancer cluster. While criminal charges and civil suits were eventually brought, we’re now fighting for appropriate restitution. We believe the NJDEP’s current settlement with the site’s owner, BASF, the world’s largest chemical company, lacks transparency and fails to account for the full environmental damage. We’ve filed an appeal and are advocating for a more just and science-based resolution that considers the lasting damage to 1,200 acres of land, the groundwater, wetlands, river, bay, and ocean.
We’re also proud to have played a leading role in the closure of the Oyster Creek Nuclear Generating Station, once the oldest operating nuclear plant in the country. The plant’s design used Barnegat Bay water to cool its reactors, then discharged superheated water back into the estuary, devastating marine life daily. We believe Save Barnegat Bay is the only grassroots environmental organization in the U.S. to successfully close a nuclear plant not on the basis of nuclear energy itself, but on its local ecological impacts.
These are just a few examples of the many efforts Save Barnegat Bay has led or supported over the years. From legislative advocacy to grassroots mobilization, our work is broad and ongoing. What unites it all is our deep commitment to protecting the Bay and ensuring its health for generations to come.”
“Barnegat Bay relies on a delicate and often overlooked network of 58 named rivers, creeks, and streams. Many of these freshwater sources originate in the Pine Barrens, winding through Ocean County and parts of Monmouth County before reaching the Bay. They are the lifeblood of the estuary, delivering freshwater that supports the Bay’s health, biodiversity, and overall ecological function.
Our “Rivers, Creeks, and Streams” campaign was created to inspire and connect people with their local waterways and take part in their protection. Whether it's through cleanup activities, water sampling, or making simple, eco-friendly changes at home, we believe small actions can collectively have a big impact.
Thanks to the generosity of local businesses, we've been able to acquire a fleet of canoes and kayaks to get people, including elected officials and community leaders, directly out on the water. This hands-on approach helps participants build a personal relationship with their local water resources, see firsthand the challenges and opportunities for improvement, and feel empowered to help. It’s one thing to talk about water quality in a meeting room, it’s another to experience it on the water, paddle in hand.”
In the video clip below, Britta shares more about this unique initiative:
“Over the years, we’ve collaborated with Princeton Hydro on a wide range of impactful projects. We've worked with many members of their team, including Dr. Steve Souza; Dr. Fred Lubnow; Geoffrey Goll, P.E.; and Mark Gallagher, just to name a few. Our work together has spanned everything from technical restoration projects to public education initiatives. In fact, we’ve probably partnered with a good portion of their staff at some point on various critical initiatives across the watershed.”
In the video clip below, Britta highlights two collaborative projects that stand out as major wins, successfully protecting sensitive habitats while navigating the priorities of various stakeholders:
Britta continues: “We’re also partnering with Princeton Hydro to take a proactive approach to water quality management in coastal towns throughout the Barnegat Bay Watershed. Specifically, we’ve been supporting Point Pleasant Beach and Bay Head in developing comprehensive lake and watershed management plans. There are three coastal lakes in Point Pleasant and one in Bay Head, and these proactive planning efforts have been incredibly valuable for those communities.
Honestly, I could go on and on. We’ve worked with Princeton Hydro on so many important projects together; it’s a true partnership.”
“There are so many ways to get involved. At Save Barnegat Bay, we encourage people to contribute and participate in whatever way works best for them—time, treasure, or talent. Nearly everything we offer is free and open to the public, from hands-on workshops like rain barrel construction to science-based programs like eelgrass planting and clinging jellyfish monitoring to volunteer initiatives like shoreline clean-ups. We’re not a membership-based organization, which means there’s no barrier to participation. You can simply show up and engage in whatever way feels right to you.
Britta leaves us with a few inspiring words about the power of big ideas, and a reminder to look beyond the everyday and believe in what’s possible:
A heartfelt thank you to Britta Forsberg for her time, passion, and leadership, and for sharing the inspiring story of Save Barnegat Bay. Her dedication to community-driven stewardship and environmental advocacy reflects the profound impact that local action can have on protecting vital natural resources on a wide-reaching scale.

Whether you're a municipal planner, community leader, contractor, public- or private-sector professional, or an academic, new to NBS or experienced in large-scale restoration projects, the guide offers value at every level with practical instruction that spans the full project lifecycle, from planning and permitting to funding and long-term monitoring. While the content is tailored to New Jersey's diverse landscapes, the guide's insights and approaches are broadly applicable to regions with similar ecosystems, from Massachusetts to Virginia.
The guide also includes insights on how to address equity considerations and foster meaningful community engagement, helping users implement NBS that are both impactful and inclusive.
Princeton Hydro was proud to contribute technical expertise to this important effort. Our Director of Restoration & Resilience, Christiana L. Pollack, CERP, CFM, GISP, participated on the guide's steering committee, and our team provided informational resources, including content and case studies on invasive species management, wetland and floodplain enhancement, and dam and culvert removal to restore rivers and improve fish passage. These contributions along with those from many other participants, reflect the collaborative nature of the guide and the collective commitment to advancing NBS across the state.
The guide's easy-to-follow format includes four key sections:
Whether you're just beginning to conceptualize a project or deep into project implementation, this guide is an invaluable addition to your toolbox. We encourage you to explore, download, and share it widely! Click here to access the guide now.
