The plant discharges into the coastal waters of Martha's Vineyard, part of the Atlantic Ocean basin. The receiving environment includes nearshore marine habitats that support shellfish beds, finfish, and migratory bird populations. As a coastal discharge, nutrient and pathogen control from secondary treatment is critical to protect water quality for recreation and ecosystem health.
