Suffolk and Nassau Counties

Suffolk County

  • Comprehensive Waste Resources Management Plan
    The Comprehensive Water Resources Management Plan analyzes groundwater and surface water quality trends and recommends measures to manage and protect these critical resources.
  • Subwatershed Planning
    This initiative is modeling parcel-specific nitrogen loads from wastewater, fertilizer, stormwater, and atmospheric deposition to the groundwater and receiving waters of 189 subwatersheds. The effort will develop nitrogen load reduction goals and will draft mitigation measures.

    The I/A OWTS program is piloting innovative and alternative technologies that can be -approved for onsite wastewater treatment.
  • Article 19 of the Suffolk County Sanitary Code
    Article 19 establishes a framework for the Department of Health Services to act as the Management Entity with the legal authority and technical capacity to ensure the long-term operation, maintenance and management of all I/A OWTS through monitoring, sampling, database tracking, and enforcement over service providers.
  • Revisions to Sanitary Code Article 5 and Article 6
    Revisions are being proposed to Articles 5 and 6 of the Sanitary Code to reduce nitrogen loading to groundwater from onsite wastewater systems.

    SHIP is a web portal that allows the liquid waste industry to report installations and pump outs of septic systems.
  • Countywide Water Quality Improvement District Study
    Suffolk County will be releasing a Request for Proposals (RFP) for the evaluation of technical and financial implications of a Countywide Water Quality Improvement District in Suffolk County.
  • Harmful Algal Bloom Action Plan
    The Suffolk County Department of Health Services Division of Environmental Quality developed the Harmful Algal Bloom Action Plan, a comprehensive strategy developed to guide the work of government, scientists, and academia to address harmful algae blooms that threaten both Suffolk County's environment and economy.
  • Coastal Resiliency Initiative
    Planning and design for sewering in the Carlls, Connetquot, Forge and Patchogue River watersheds is underway.

Nassau County

  • Subwatershed Planning
    Nitrogen load and hydrodynamic modeling is underway to estimate the nitrogen loading from wastewater, fertilizer and atmospheric deposition to surface and ground waters and to develop strategies to reduce those loads.
  • Stormwater Model
    A stormwater model is being developed to estimate and prioritize stormwater nitrogen loads generated in each of the County's subwatersheds.
  • Reconstruction of the Bay Park Wastewater Treatment Plant (WWTP)
    A major reconstruction and resiliency upgrade is underway at the Bay Park WWTP which was severely damaged by Hurricane Sandy.
  • Nitrogen Removal Initiative for Bay Park Wastewater Treatment Plant
    A nitrogen removal initiative for the Bay Park WWTP is underway aimed at reducing nitrogen output to the Western Bays.
  • Diverting Bay Park WWTP Effluent to the Ocean
    An engineering feasibility study is in progress to evaluate diversion of Bay Park WWTP effluent to the Cedar Creek WWTP ocean outfall through an unused pipe beneath Sunrise Highway.
  • Point Lookout Sewering Study
    Nassau County was awarded funds to design and construct sewer infrastructure for Point Lookout to connect to the existing Waste Water Treatment Plant (WWTP) in Long Beach.
  • Septic Incentive Grant and Loan Program
    The Septic Incentive Grant and Loan Program will provide grants and loans to homeowners to replace non-performing septic systems or cesspools with an I/A OWTS designed to significantly reduce nitrogen pollution.
  • Long Beach Wastewater Treatment Plant
    The City of Long Beach entered into a Consent Order with NYSDEC committing to the planning, design, construction, and operation of a project to divert wastewater from the Long Beach Waste Water Treatment Plant (WWTP) to the Bay Park WWTP for treatment and discharge. The Long Beach WWTP would be converted to a pump station to enable this change.

Long Island Regional Planning Council (LIRPC)

  • Nassau County Water Quality Monitoring Program
    The LIRPC will launch a program to collect, analyze and report on water quality data from Nassau County's south shore surface waters. The project goals are to expand water quality monitoring and provide uniform analysis and reporting.
  • Long Island STEM Program
    The LIRPC is developing a Science, Technology, Engineering, and Mathematics (STEM) Challenge Program for Nassau and Suffolk County public schools. The goal developed for this initiative is to connect students, teachers, and their communities with two issues being addressed by LINAP to reduce pollutant loads to our groundwater and surface waters.
  • Nitrogen Smart Communities
    The LIRPC is developing a program where a city, town, village or county in New York can become a Registered Nitrogen Smart Community. The municipality's governing body must adopt a resolution that includes all elements of the Nitrogen Smart Community criteria.
  • Nutrient Bioextraction Initiative
    The goal of the Nutrient Bioextraction Initiative is to improve water quality in NY and CT marine waters by removing excess nitrogen through the cultivation and harvest of seaweed and shellfish. The Initiative will provide information to help decision makers with the guidelines needed to facilitate seaweed and shellfish farming and harvest operations in their coastal waters.
  • Data Collaboration Project
    Development of a data management portal that will allow multiple entities to store groundwater and surface water monitoring data in one comprehensive, multi-functional data repository.

For more information about LIRPC please visit their website.

Estuary Programs

Peconic Estuary Program

  • Comprehensive Resource Management Plan
    The CRMP, currently in the process of being updated, addresses brown tide, nutrients, habitat and living resources, pathogens, toxic pollutants, and critical land protection with a goal of protecting and improving the resources of the estuary and its watershed.
  • Homeowners Rewards Program
    A rewards program for homeowners who use landscaping that benefits the environment.

Other Partners

United States Geological Survey (USGS)

  • Solute Transport Model
    The USGS in cooperation with the Peconic Estuary Program (PEP), will study: the definition of nitrogen sources within the watershed over time, the development of numerical models and methods capable of simulating nitrogen transport from those sources to wells and ecological receptors, and the application of those methods to estimate time-varying nitrogen loads resulting from wastewater management actions and evaluate nitrogen attenuation.

Center for Clean Water Technology (CCWT)

The CCWT is developing and commercializing cost-effective water quality protection and restoration solutions. Its initial focus is delivering affordable, high performance technology to efficiently remove nitrogen and other contaminants from household wastewater to replace or retrofit existing cesspools and septic systems.

  • Nitrogen Removing Biofilters
    CCWT is researching passive, non-proprietary systems that can achieve up to 90 percent nitrogen removal along with efficient removal of contaminants of emerging concern.
  • Constructed Wetlands
    The CCWT is evaluating a constructed wetland system on Shelter Island in collaboration with Suffolk County. The Center has also installed pilot-scale experimental wetlands at the Massachusetts Alternative Septic System Test Center to answer specific research questions important for constructed wetland design.
  • Permeable Reactive Barriers
    The Center continues to evaluate the potential of small-scale Permeable Reactive Barrier (PRB) installations for nitrogen removal.
