The Massachusetts Department of Public Health sent the following email to the city  regarding the most recent testing results at Crystal Lake.

A water sample was collected at Crystal Lake on Monday August 6th. Laboratory analysis showed cyanobacteria levels of 83,000 cells/ml, exceeding the MDPH guideline level of 70,000 cells/ml. Microcystin toxin level was <1 ppb.

We recommend that the current advisory remain in place and will sample again next week. Thank you.
