Consumer Confidence Reports

The Consumer Confidence Rule requires public water suppliers that serve the same people year round (community water systems) to provide consumer confidence reports (CCR) to their customers. These reports are also known as annual water quality reports or drinking water quality reports.

Water Quality Analysis

If you would like to have your private well or your water quality tested at an independent laboratory, several local laboratories are listed below. The MassDEP has a searchable database of laboratories that you can use to find a laboratory on your own. Please read the MassDEP's guidance document on things to consider when choosing a laboratory.


According to the Boston Globe, the town of Ayer, like many towns located near military bases, has discovered that town wells near Fort Devens tested positive for the toxic substances like PFAS, some significantly in excess of what public health officials consider safe. The EPA has never required public water departments to test for PFAS (Per- and polyfluoroalkyl substances), but the EPA is now developing guidelines on upper limits for PFAS and may require testing in the future.
