Suffolk County:
Suffolk County’s Subwatersheds Wastewater Plan (SWP) is a comprehensive look at the state of the nitrogen pollution in Suffolk County. The Plan has modeled nitrogen loads from wastewater, fertilizer and atmospheric deposition at the parcel level to the groundwater. Using the model’s data, load reduction goals have been developed for all Suffolk County waterbodies. The plan’s recommendations will allow Suffolk County to target priority areas for reducing nitrogen coming from wastewater.
Nassau County:
The Nassau County Nine Element Plan is an analysis of Nassau’s north and south shore bays and surrounding watershed, which includes modeling the nitrogen inputs to each embayment from wastewater, fertilizer, atmospheric deposition, and storm water, modeling hydrologic residence times, and a water quality data analysis. The Plan is an update to a report published in 2020. The report is undergoing updates and stakeholder engagement before as it is being converted into a Nine Element Watershed Plan. This was a joint effort between Nassau County, Stony Brook University School of Marine and Atmospheric Sciences, and DEC. More information on the plan can be found on Nassau County’s 9E Plan webpage.
