Long Island Sound is one such water body at risk to substantial residentially-sourced nitrogen loading.&nbsp; Marsh Institute Director <strong>Robert Johnston<\/strong>, in collaboration with researchers at University of Connecticut, University of Maryland, and University of Miami, received funding from New York Sea Grant for the project <em>Reducing Non-Point Source Nitrogen Loads from Residential Septic Systems: Identifying Barriers and Opportunities for Large-Scale Water Quality Improvements<\/em>, which will develop an integrated, spatially-explicit economic-behavioral-hydrological model to inform the design and targeting of programs to reduce Long Island Sound non-point source nitrogen loads from residential onsite wastewater treatment systems. This work will significantly advance public understanding of opportunities and barriers to reduction of nitrogen from residential parcels, provide a tool that predicts household adoption of alternative onsite wastewater treatment technologies under alternative programs and scenarios, and identify how programs can be optimally designed for cost-effective nitrogen-load reduction.<\/p>\n\n\n\n<p>For full project descriptions, see the <strong>Marsh Institute Research Projects<\/strong> <a href=\"https:\/\/www.clarku.edu\/marsh-institute\/research\/research-projects\/\">web page<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Residential septic systems are a primary source of nitrogen loading to nearby water bodies which can negatively impact water quality.
