PFAS
BCAT Update from June 22, 2022
Explanation of Quarterly Public Notice
The quarterly public notice is required to be sent to residents within 30 days of a PFAS violation. The notice states, that based on our first two months of PFAS sampling and monitoring, even if the third month results were zero (0), our quarterly average would not be within in compliance of the 20 parts per trillion (ppt) maximum contaminant level (MCL).
Based on this, when the average of month one + month two + zero is greater than the MCL of 20 ppt, we are already placed in violation by MassDEP by the end of month two. The public notice pamphlet is then generated and sent prior to the results of month three being completed since the notice has to be sent within 30 days of violation.
Please refer to the example tables below for reference.
Example One
| Month One | 35.4 ppt |
| Month Two | 36.7 ppt |
| Month Three | 0 ppt |
