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.
  • Septic/Cesspool Upgrade Program Enterprise (SCUPE)
    SCUPE is developing and will implement programmatic infrastructure to address nitrogen and pathogen loadings from existing septic system or cesspool effluent.
  • Innovative/Alternative Onsite Wastewater Treatment Systems (I/A OWTS)
    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.
  • Septic Incentive Program
    The Septic Incentive 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.
  • Fertilizer Law and Outreach
    Applying lawn fertilizer in Suffolk County from November 1 to April 1 is prohibited. More information, including other provisions of the law and lawn care best management practices, are available on the County's Healthy Lawns, Clean Water website.

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 County-wide 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.
  • Crescent Beach Groundwater Assessment and Stream Sampling
    A groundwater assessment and stream sampling program will identify the source of bacterial contamination that has led to the closing of Crescent Beach by the Nassau County Department of Health.

Estuary Programs

Peconic Estuary Program

  • Comprehensive Resource Management Plan
    The Plan addresses brown tide, nutrients, habitat and living resources, pathogens, toxic pollutants, and critical lands protection will a goal of protecting and improving the resources of the estuary and its watershed.

Long Island Sound Study

  • Enhanced Nitrogen Reduction Strategy
    The initiative will help reduce nitrogen and improve water quality throughout the Long Island Sound, its embayments, and near shore coastal waters.

South Shore Estuary Reserve

  • Comprehensive Management Plan
    The Plan details actions to improve and maintain water quality, protect and restore living resources, expand public use, sustain and expand the estuary economy, and increase education, outreach, and stewardship.
  • Coordinated Water Resources Monitoring Strategy
    This document describes monitoring needed to help guide future efforts to improve water quality in the South Shore Estuary Reserve.
  • Eastern Bays Project: Sources and Management Options
    The report estimates the amount of nitrogen entering the Eastern Bays of the Reserve from non-point sources of nitrogen and describes mitigation measures.

Other Partners

United States Geological Survey (USGS)

  • Aquifer Sustainability Study
    The USGS is developing a groundwater model for Long Island's principal aquifer systems that addresses long-term sustainability in terms of inputs and outputs. It will recommend protective measures to avoid aquifer depletion and saltwater intrusion.

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.
  • Other Research and Development
    Additional efforts are aimed at improving the nitrogen removal efficiency and cost effectiveness of constructed wetlands, permeable reactive barriers, and membrane bioreactor technology.

Long Island Commission for Aquifer Protection (LICAP)

LICAP is a bi-county entity formed to address both quality and quantity issues facing Long Island's aquifer system, and to advocate for a coordinated, regional approach to groundwater resources management.

  • Groundwater Resources Management Plan
    LICAP is drafting a plan that will include qualitative and quantitative groundwater data, anthropogenic threats to groundwater quality and quantity, and an assessment of the adequacy of existing groundwater management regulations.
  • Water Traq
    LICAP developed this online tool that tracks potential threats to the public drinking water supply.
