Reducing Nitrogen Loading With Enhanced Septic Systems: Social and Environmental Considerations Webinar
Traditional septic systems do little to remove nitrogen from wastewater, which has resulted in excess nitrogen in the surrounding environment. Excess nitrogen from septic systems and other human activity can threaten estuaries, wetlands, drinking water sources, and freshwater ponds as they contribute to algae blooms, low dissolved oxygen, degradation of seagrass, impaired freshwater and estuarine ecosystems, and in extreme cases, fish kills.
In this webinar, participants will learn and report on preliminary results of a project implementing a neighborhood-scale demonstration of enhanced innovative/alternative (IA) septic systems in Barnstable, Massachusetts, including:
- How the enhanced IA septic system designs have shown promise for removing much of the nitrogen before it enters surrounding groundwater, estuaries, and ponds.
- Replacement of traditional septic systems with one of two new IA septic systems designed to increase the removal nitrogen from wastewater.
This U.S. EPA study is in partnership with the Barnstable Clean Water Coalition, Massachusetts Alternative Septic System Test Center, U.S. Geological Survey, Town of Barnstable, and others. The study is part of a larger pilot project at U.S. EPA focused on evaluating promising interventions with a goal of reducing excess nitrogen in the Cape Cod region.
