Nitrogen

Nitrogen (N) from residential lawn fertilizer is one of the most challenging and persistent problems impacting the health of Long Island Sound (LIS). An interdisciplinary team of researchers from Clark University, the University of Connecticut, the University of Maryland, and the University of Miami collaborated on an effort to better target education and outreach campaigns to reduce the use of lawn fertilizer in areas of greatest impact. 

This Story Map and the associated Lawn Fertilizer Outreach Targeting Tool can help identify areas of the watershed for which interventions to reduce lawn fertilizer may have greater impacts.

The Connecticut Department of Energy and Environmental Protection (DEEP) is now accepting proposals for fiscal year 2025 Clean Water Section 319 grants.  Section 319 of the Federal Clean Water Act (Section 319) is a Federal program to control nonpoint sources (NPS) of water pollution.  Connecticut receives funds from EPA for Section 319 grants that can be passed onto communities, local conservation groups, and other organizations for NPS implementation projects, plans, and statewide NPS management efforts.

The New England Grassroots Environment Fund awards small grants in support of grassroots efforts and community-based environmental work in New England. The GROW GRANTS program is actively accepting applications from grassroots groups across New England.

The LINAP Embayment Water Exchange Study looked at how water exchange practices could affect the nitrogen impairments in embayments. A water exchange practice changes the amount, speed, or direction of water moving through an area. The results of the study show that water exchange techniques are not effective in large waterbodies like most of Long Island’s embayments. Often, the physical size of the water exchange practice is small compared to the large waterbodies to which they are applied, which means their impact is limited. Water exchange projects may be useful, however, for smaller Long Island waterbodies, where the volume of increased water exchange approaches the volume of the overall waterbody. The goal of the study was to provide communities with basic information on water exchange practices suitable for Long Island.

The NYS Department of Environmental Conservation (NYSDEC) WQIP funds implementation projects to improve water quality or habitat, promote flood risk reduction, restoration, and enhanced flood and climate resiliency, or protect a drinking water source.

The Agricultural Nonpoint Source Abatement and Control Program awards water quality protection projects that focus on environmental planning and best management practice systems. Projects include conservation measures, such as nutrient management through manure storage, vegetative buffers along streams, and conservation cover crops.

Nassau County has initiated a septic system replacement program for residents, small businesses, and nonprofits – Septic Environmental Program to Improve Cleanliness (SEPTIC). The SEPTIC program will reimburse eligible recipients that replace a conventional or failing septic system with an innovative and alternative onsite wastewater treatment system.

Under this program, homeowners who replace their cesspool or septic system with new Innovative and Alternative Onsite Wastewater Treatment Systems (I/A OWTS) technologies may be eligible for grants from New York State and Suffolk County that enable them to purchase and install a nitrogen removal septic system and leaching structure.

This program provides financial rewards for homeowners on Long Island who add green alternatives to their properties that reduce stormwater and nitrogen pollution entering Long Island Sound. Homeowners can be reimbursed for installing rain barrels, rain gardens, or native plantings on their properties. Application opened April 22nd, 2025 for this current season. Funds are limited and available on a first come, first serve basis.

Due to the high participation in the program, as of May 20, 2025 the Long Island Garden Rewards Program is closed. Thank you to all who participated. Check back for when applications open again!
