The Division of Environmental Quality (DEQ) conducts comprehensive programs that protect Suffolk County residents against adverse environmental factors. DEQ programs also preserve and enhance the generally high quality of the Suffolk County environment.
The major programs of the Division of Environmental Quality are groundwater and drinking water protection, wastewater management, toxic and hazardous materials pollution control, monitoring and laboratory analyses, enforcement of regulations, and environmental management studies and programs for groundwater and surface waters, including related ecological issues. These programs are managed through the five offices of the division: Water Resources, Pollution Control, Wastewater Management, Ecology, and the Public and Environmental Health Laboratory.
The Division’s Board of Review hears requests for variances and waivers, meeting on the third Thursday of every month, with the exception of December, when the meeting is on the second Thursday of the month. A listing of each month’s scheduled hearings may be obtained by contacting the division at 852-5800. On alternate Thursdays, voting for previous hearings may be recorded.
In response to the growing water quality crisis facing our county, the Suffolk County Department of Health Services has developed an historic solution to address nitrogen pollution through the development of a countywide wastewater upgrade strategy. A Reclaim Our Water initiative, the strategy is documented in the Suffolk County Subwatersheds Wastewater Plan (SWP), which was developed in partnership with the Long Island Nitrogen Action Plan (LINAP) and in collaboration with numerous project partners, stakeholders, and technical experts. The SWP is the product of years of intensive research, documentation, modeling, and evaluation of all of Suffolk County’s water resources and provides a parcel-specific roadmap on how to address the nitrogen crisis through wastewater upgrades and other nitrogen pollution mitigation strategies. The plan seeks to arrest and reverse the existing trend of degrading water quality over a 10 year period by transitioning away from reliance on conventional cesspools and septic systems, which are the primary source of nitrogen pollution that has fouled local bays.
