Harbor-Wide Water Quality Monitoring Report 2021
The Harbor-Wide Water Quality Monitoring Report analyzes water quality data collected in 2010 to 2017 during the months of June through September and compared average values relative to the federal Clean Water Act goals as well as current regulatory standards in the Harbor Estuary. Water quality is described by concentrations of pathogenic bacteria, such as Enterococcus and fecal coliform, which are used to determine safety for human contact. Another parameter, dissolved oxygen, is used to assess the ability of a waterway to support fish and other aquatic organisms. In addition, the report explores total nitrogen and chlorophyll-a concentrations to inform how these parameters may impact dissolved oxygen concentration in a waterbody.
Connecting Passaic to the River: Dundee Island Waterfront Park and Community Engagement Profile
HEP, Lower Passaic River Urban Waters Federal Partnership, and USDA Forest Service partnered to create this social assessment study in order to obtain a deeper understanding of how higher-need waterfront communities use and value their closest available open space resources, such as urban waterways, and identify the types of programs and public access opportunities that will best engage waterfront community members to the nearest and most accessible open space. Given the lack of available open spaces in higher-need areas of the estuary, improving public access and the quality of experience at existing public spaces is of great importance in order to reconnect communities to their open space resources.
2019 Post-Construction Oyster Monitoring Report: The Governor Mario M. Cuomo/New NY Bridge Project at Tappan Zee Oyster Substrate and Water Quality Monitoring
This preliminary oyster reef and water quality monitoring report follows up on the implementation of the largest oyster restoration effort to take place in the Hudson River Estuary to date. 881 reef balls and 422 oyster shell filled gabions were deployed over an area of approximately six acres at three locations in the vicinity of the Governor Mario M. Cuomo Bridge in the summer of 2018. A second more comprehensive monitoring report will be prepared after the second monitoring season is completed in the fall, 2020.
Progress Report: Restoring the New York-New Jersey Harbor Estuary 2017-2019
Presented at HEP’s 2019 Restoration Conference: Lessons Learned for a Changing Future, this report addresses the achievements made by the HEP Restoration Work Group Partners between 2017 and 2019, and overall progress towards the 2020 and 2050 goals.
Environmental Projects in Urban Areas: Analysis to Support Project Planning and Budgeting for the US Army Corps of Engineers
Boyd, J. and Shabman, L., 2019.
Leonard Shabman and James Boyd from Resources for the Future were asked by the Hudson River Foundation to identify the analytical and institutional practicality of developing restoration evaluation criteria that places greater emphasis on restoration’s social (ecosystem service) benefits. Their report investigates the US Army Corps of Engineers project planning and budget justification practices for dredge material handling, inclusion of natural and nature-based features in storm reduction projects, and aquatic ecosystem restoration, asking why Corps planning and budgeting practices do not currently consider ecosystem services benefits, such as water quality improvement and recreation. Shabman and Boyd propose methods to cost effectively report on a wider array of benefits that might be used in Corps budget decision making and by government and non-government organizations that pay a share of the cost of Corps projects. The results will be used by the Foundation and its partners in the New York- New Jersey Harbor & Estuary Program to inform research needs and project justification.
Benthic Infaunal Communities and Sediment Properties in Pile Fields within the Hudson River Park Estuarine Sanctuary
Taghon, G.L., Petrecca, R.F., and Fuller, C.M. 2018. Rutgers, the State University of New Jersey.
A core mission of the NY-NJ Harbor & Estuary Program, along with the Hudson River Foundation, is to advance research to facilitate the restoration of more, and better quality, habitat. Pile fields are legacy piers that have lost their surfaces and exist as wooden piles sticking out of the sediment. Pile fields have been extolled as good habitat for fish. There is no definitive answer, however, as to why and how fish and other estuarine organisms use the pile fields. The project and results described in this report address a small portion of that larger question by assessing if the structure of the benthic community may have some bearing on how the pile fields are used as habitat. Benthic infauna, the invertebrates living in bottom sediments, were the focus of this project.
Opportunities to Advance Wetlands Migration Pathway Protection
HEP commissioned an assessment of regional knowledge, activities, needs, and opportunities related to the protection of pathways for tidal wetlands to advance inland as sea level rises. These pathways are a cornerstone of tidal wetlands conservation and resilience, and necessary to maintain the ecosystem, economic, and community resilience services these wetlands provide. This report summarizes findings from interviews with 22 coastal researchers, environmental conservation leaders, and public agency officials who have been involved in coastal resilience at the municipal, county, state, and federal levels in the HEP region.
Climate Change Effects on Water Quality and Biota
Climate change is impacting the health and biological integrity of the New York – New Jersey Harbor Estuary. Rising average air and water temperatures, more frequent and extreme weather events, and steadily rising sea levels are already changing baseline conditions and affecting the Estuary’s aquatic habitats and biota. The magnitude of these ecological changes is expected to increase in the future. The New York – New Jersey Harbor & Estuary Program (HEP) has identified gaps in understanding these projected Increases in temperature as a key vulnerability of its program to meet goals for fish survival and reproduction. The objective of this review is to summarize existing research on potential impacts of projected temperature and precipitation changes on estuarine biota (with emphasis on fish survival and reproduction) in NY/NJ Harbor Estuary, including changes in dissolved oxygen, harmful algae blooms, and other parameters.
2017-2022 Action Agenda
This new NY-NJ HEP report identifies five long-term goals, 17 objectives, and 40 specific actions that will help enable people and wildlife to benefit from the fishable and swimmable waters called for by the Clean Water Act.
2018 State of the Estuary Report
The State of Estuary Report compiles the best available data for 31 indicators selected by scientific and technical experts convened by the New York – New Jersey Harbor & Estuary Program (HEP). Where possible, this scientific information is used to illuminate long-term (roughly 30 years) and shorter-term trends, providing a broad assessment of progress toward HEP’s goals of improving water quality, habitat, public access, maritime operations, and community engagement.
2018 Environmental Monitoring Plan
Fifty-one indicators, selected by scientific and technical experts convened by the New York-New Jersey Harbor Estuary Program (HEP), can help us understand and document progress towards improvements in water quality, habitat, public access, maritime use, and community engagement. To help coordinate these monitoring efforts, improve data analysis, and make data available, HEP has produced an Environmental Monitoring Plan. This new HEP monitoring plan identifies the kinds, sources and spatial coverage of available monitoring data collected in the estuary, including data on water quality and fish and wildlife.
Climate Change And its Impact on the New York/New Jersey Harbor & Estuary Program
This new report assesses how the risks associated with climate change stressors such as rising sea levels, warmer air and water temperatures, and increases in extreme weather will impact estuary management. The report was prepared to gain a greater understanding of how the risks associated with climate change stressors will limit the ability of HEP to reach its goals for reducing pollution, improving and increasing habitat and public access, supporting maritime uses, and engaging communities.
Options for Funding Program Priorities
This report describes 28 potential funding sources to broaden the depth and breadth of funding available for implementing the HEP Action Agenda. The purpose of this document is to explore a wide range of potential funding sources in order to broaden the depth and breadth of funding available for implementing the HEP Action Agenda and realizing the shared goals for the Estuary. It is intended to serve as a basis for discussion among HEP partners to identify and advance the best candidate funding sources upon which to move forward.
Preliminary Evaluation of the Physical Influences of Storm Surge Barriers on the Hudson River Estuary
Storm surge barriers are being evaluated by the Corps of Engineers as an option for flood risk reduction for the New York City metropolitan area under the New York/New Jersey Harbor & Tributaries Focus Area Feasibility Study. The decision of whether or not to build surge barriers to protect one of our nation’s main commercial hubs and ports, crossing one of our most iconic estuaries, is a major decision worthy of thorough analysis of potential impacts. Storm surge barriers have the potential to cause large‐scale changes to the Hudson River estuary ecosystem. This report, commissioned by the New York ‐ New Jersey Harbor & Estuary Program and the Hudson River Foundation, presents a first look at the possible direct influences of hypothetical surge barriers on physical conditions in the Hudson River estuary.
Planning and Technical Support for Incorporating Green Infrastructure in Long Term Control Plans
This work will help Perth Amboy and its partners advance a variety of green infrastructure projects as part of its Long Term Control Plan (LTCP). The report is intended to inform the New Jersey Department of Environmental Protection, New Jersey CSO and Harbor Dischargers Groups, Jersey Water Works, and other stakeholders in the LTCP process as to what might be an ambitious and realistic target for balancing green and gray infrastructure. NJ DEP, like the federal EPA, has recognized green infrastructure as an important part of an integrated solution to water management. With two representative study areas within the City of Perth Amboy as a subject, this study demonstrates the potential effectiveness that GI can have in reducing the amount of stormwater entering the combined sewer system.

Hudson-Raritan Estuary Comprehensive Restoration Plan
Under the authorization of Congress in 1999, the US Army Corps of Engineers and The Port Authority of New York and New Jersey facilitated the development of the Comprehensive Restoration Plan (CRP). It was created collaboratively by scientists, professionals, government agencies, nonprofit organizations, academic institutions, and environmental advocates with the assistance of the Hudson River Foundation. The plan is a blueprint to protect those habitats that still exist and restore habitats that have been lost. Following a draft version in 2009, the final CRP was released in 2016. The Ecosystem Restoration Feasibility Study is advancing implementation a number of specific restoration projects.
Plan contents, including an executive summary, technical companion report, and progress report can be found on the Hudson-Raritan Estuary Comprehensive Restoration Plan page.

This CARP Summary Report provides a brief overview of all the data and modeling results conducted under CARP from 1999 through 2006. The report is meant to serve as a reference tool and roadmap to the more detailed information found in the numerous technical reports, data archives, modeling reports and research papers.
Working Together to Improve the NY-NJ Harbor Estuary: Contributions by Partners of the NY-NJ Harbor & Estuary Program
Oyster Restoration Research Project Final Technical Report
This report describes the results of the Oyster Restoration Research Project (ORRP) Phase I (2010-2012) studies to assess development (oyster retention, growth and survival) and performance (water filtration and habitat provision) at five experimental reef sites (Bay Ridge Flats, Governors Island, Hastings, Soundview and Staten Island). This report also provides an assessment of where additional efforts should be focused and questions that need to be answered. Because the constructed experimental reefs essentially replaced the habitat that existed at the time of construction, there is a need to understand these changes on the broader ecosystem.
The State of the Estuary 2012
The State of the Estuary 2012 report was produced by the New York-New Jersey Harbor & Estuary Program (HEP) in partnership with the New England Interstate Water Pollution Control Commission (NEIWPCC). This 2012 report showcases the environmental health and trends of the NY-NJ Harbor Estuary, focusing specifically on living resources, pollution, climate change, and public access.
Total Maximum Daily Load Reports
Total Maximum Daily Loads (TMDLs) are developed by each state for all waters identified on their Section 303(d) list of impaired waters. TMDLs determine the maximum pollutant load allowed to enter the waterbody and continue to meet water quality standards. To view reports about TMDLs developed by the Water Quality Work Group, go to the TMDL page:
Rapid Assessment of Habitat and Wildlife Losses from Hurricane Sandy in the Hudson Raritan Estuary

Harbor-Wide Water Quality Monitoring Report for the New York-New Jersey Harbor Estuary
This report was developed under the auspices of the New York-New Jersey Harbor Estuary Program (HEP), and is the collaborative effort of many partners. This is the second report in what HEP envisions to be a series of water quality trend assessments for the New York-New Jersey Harbor Estuary. The data analyzed for this report include fecal coliform, Enterococcus, and dissolved oxygen, and focus on the data collected in 2007-2009. Long term monitoring programs, such as that of the City of New York, have documented dramatic improvements in water quality since implementation of the Clean Water Act began in the 1970s. With significant new investments in wastewater treatment and combined sewer infrastructure, HEP believes it is prudent to monitor the influence of these projects on ambient water quality, and to expand the monitoring to include all of the Harbor waters.
Fish Passage Feasibility Evaluation of the Rahway River Water Supply Dam in Rahway, New Jersey (NJ)
Under a grant provided in 2007 by the United States Environmental Protection Agency (USEPA) New York – New Jersey Harbor Estuary Program (HEP), Weston Solutions Inc. (Weston®) has prepared this report focusing on recommendations and data gaps identified during the Final Preliminary Fish Passage Feasibility Evaluation for the Rahway River Water Supply Dam, Rahway, New Jersey completed in March 2006 (Weston, 2006). The objective of this evaluation was to conduct continued assessment of the feasibility of anadromous and catadromous fish passage at the Rahway Water Supply Dam in Rahway, NJ. The study indicated that while there are hurdles to the potential installation of a fish ladder at the Water Supply Dam location, the project is generally feasible.

Bain, M., D. Suszkowski, J. Lodge, and L. Xu. 2006. Cornell University and the Hudson River Foundation.
An interdisciplinary workshop with scientific experts and agency representatives was conducted in 2005 to develop candidate objectives to guide restoration planning. The workshop was structured to generate target ecosystem characteristics (TECs) to serve as program objectives. TECs are the broadest planning element defined in measurable terms and the precise ecosystem conditions to be promoted in restoration projects. The workshop succeeded in developing many (23) and varied ecosystem targets.
Guide to Harbor Herons and Other Colonial Waterbirds of the NY-NJ Harbor Estuary
In the hustle and bustle of the NY-NJ Metropolitan region, it is all too easy to forget that our homes and workplaces are built atop a series of islands and peninsulas – and surrounded by an estuary where fresh water from rivers meets the salt water of the ocean. Scattered across this urban archipelago are many smaller islands, where the most prominent inhabitants are a surprising number of birds known as the Harbor Herons. This guide showcases the harbor herons that live in our urban landscape.
The Health of the Harbor Report
Steinberg, N., D.J. Suszkowski, L. Clark, J. Way. 2004. Hudson River Foundation, New York, NY.
The Hudson River Foundation prepared a report in 2004 for the New York-New Jersey Harbor Estuary Program which showed that scientific measures of the environmental health of New York Harbor had improved as much as ten-fold in the preceding 30 years. The Health of the Harbor Report – the first comprehensive look at the environmental conditions of the estuary – examined trends by tracking key environmental indicators over time and across the harbor.
Harbor Health/Human Health: An Analysis of Environmental Indicators for the NY/NJ Harbor Estuary
The health of the NY/NJ Harbor Estuary and the health of the more than 20 million people who live near it are inextricably related. Contaminants that enter our waters tend to bioaccumulate in fish and shellfish, sometimes causing warnings about their consumption to be issued. High levels of bacteria in the water can cause shellfish beds
and beaches to be closed to human use to prevent people from getting sick. In this 2002 analysis, HRF and HEP reported on trends in environmental indicators that are related to human health. Temporal and spatial trends are assessed as the existing data allow, and references to go to for further information are listed.
Highlights of Program Accomplishments and Challenges for the Future – Report by the CAC and the STAC
This document was part of a larger effort to re-energize the Harbor Estuary Program. The purpose was to take stock of progress, re-evaluate the program objectives, set targets for restoration of the estuary and determine the future direction for the program. The Citizens Advisory Committee (CAC) and the Science and Technical Advisory Committee (STAC) of the HEP ensure that the voices of the public and the scientific community are considered in the management of HEP and the implementation of the CCMP.
