MANCHESTER, NH – The public beach at Crystal Lake was closed following routine water testing on July 17 indicating elevated levels of e.coli bacteria.
Retesting of the water was done on July 18 by the Manchester Department of Health. Results are expected July 19, and if the levels are within the safe range, the public beach will be reopened at that time.
In accordance with NH RSA 485-A, Class B waters, those acceptable for fishing, swimming and other recreational purposes are tested weekly, and shall not have greater than an average of 88 Escherichia coli (E-coli) per 100 milliliters of water.
When water sample results are greater than an average of 88 E-coli per 100 milliliters, the Manchester Health Department may close the area to swimming until the levels are acceptable.
