MANCHESTER, NH – The Manchester Health Department announced Tuesday that the public beach at Crystal Lake has been closed to swimming due to elevated levels of
E. coli bacteria. This is the second time this season that the lake has been closed for E. coli.
The elevated bacteria levels were identified in a routine water sample taken on August 1, 2016 of the right lake. Water samples taken at other locations on Crystal Lake did not find elevated levels of E. coli bacteria.
Results at Crystal Lake: E. Coli per 100 ml: 1414 Lake Right
E. Coli per 100 ml: 32 Lake Left
Elevated levels of E. coli were also detected at the Merrimack River/Fisher Cat CSO.
In accordance with NH RSA 485-A, Class B waters, those acceptable for fishing, swimming and other recreational purposes, shall not have greater than an average of 88 Escherichia coli (E-coli) per 100 milliliters of water.
The Health Department will be re-sampling the area on August 2, 2016. Once E. coli levels are found to be acceptable, the public beach will be reopened for swimming.
Elevated levels of E. coli were also detected at the Merrimack River/Fisher Cat CSO.
