Edgartown wastewater authorities believe a plan to sewer hundreds of homes in the watershed of the Edgartown Great Pond can achieve the 30 per cent reduction in nitrogen pollution required to restore it to health.
A draft report of the Massachusetts Estuaries Project, obtained and published by the Gazette last week, finds the Great Pond’s water quality is significantly affected by heavy nitrogen loading. The biggest single contributor to the problem is household septic systems, the report found.
