On Long Island, economic prosperity, public health and safety, and our quality of life rely upon the integrity of water that surrounds us. While all sources of water pollution have an impact on water quality, nitrogen pollution from failing septic systems has clearly emerged as the most widespread and least effectively addressed of the region’s growing cocktail of water pollutants. Suffolk County, with a population larger than 11 states and a region that derives its drinking water from the ground, must pay particular attention to the 360,000 septic/cesspools in Suffolk, accounting for 74% of the homes.

Suffolk County is fully committed to its stated mission to reduce nitrogen loading to our surface and ground water from all sources. Excessive nitrogen loading from septic systems and cesspools are the most substantial sources of nitrogen in our waters. Suffolk County is preparing for the installation of new, improved onsite septic systems to reduce nitrogen loadings from sanitary waste.
