Cyanobacteria levels at Willis Lake found below guidelines
Results of cyanobacteria testing taken July 27th, 2015 at Willis Lake showed levels below the Massachusetts Department of Public Health guidelines. In addition, the MA Dept. of Environmental Protection conducted their own sampling at Willis Pond this week, also on Monday. They shared their results with us, and also found cyanobacteria levels below the guideline.
According to MDPH guidelines, samples collected a week apart with levels below the guidelines are required before the advisory should be lifted. The result above will be considered the first low sample, and MDPH will sample at the water body again next week. We recommend that the current advisory remain in place for now
