The combined effect of NPS pollutants such as phosphorus, sediment, and bacteria is degraded water quality and loss of recreational use and wildlife habitat. This accelerated degradation as a result of human activity in the watershed is called “cultural eutrophication”.  

S Excessive nutrients such as phosphorus stimulate algal and plant growth, limiting the recreational use of Rock & Pentucket Ponds (fishing, swimming, and boating) and degrading wildlife habitat.
S Sediment can cause serious damage to the ponds by causing turbidity and filling-in sensitive habitat that is needed for aquatic life. It also transports phosphorus.

S Bacteria from failing or substandard septic systems, pet waste, and waterfowl can cause swimming beach closures, such as at our Pentucket Pond Town Beach at American Legion Park.
