* For reference, a “part per trillion” or “ppt” is a microscopic measurement for substances in the water and is equivalent to a single drop of water in the combined water volume of 20 Olympic-sized swimming pools.

** Quarterly averages are calculated by adding the three-monthly sample results from within the quarter and dividing by three. If multiple samples are collected in the same month, then the samples shall be averaged to establish a single contaminant concentration for that month. Beginning April 2021, if the quarterly average exceeds 20 ppt of PFAS6, the MCL established by the MassDEP has been violated.
