The Comprehensive Watershed Management Plan (CWMP) for the Town of Truro focuses primarily on nitrogen load reduction in its three coastal watersheds: Wellfleet Harbor, East Harbor (Provincetown Harbor), and Pamet River. The documents outline the need for nitrogen management due to existing Total Maximum Daily Loads and impaired water quality, detailing an Alternatives Screening Analysis of various management strategies, including conventional and innovative/alternative (I/A) nitrogen-reducing septic systems, permeable reactive barriers, and cluster wastewater treatment systems.
