Septic Systems, especially those in the Critical Area, can be a significant source of nitrogen pollution when they are failing or are not maintained in good condition. Conventional septic systems deliver a large portion of the nitrogen into the groundwater and ultimately into our rivers. New nitrogen-reducing systems can dramatically reduce the amount of nitrogen pollution coming from a septic system. Grant money may be available from the Bay Restoration Fund to offset costs of replacing older septic systems with newer nitrogen reducing models.
