Water Quality Reports

Keeping you informed

Aquarion keeps you informed about the results of the extensive, exacting monitoring on your water supply through the publication of annual water quality reports. These publicly accessible reports document how our water continues to meet or exceed the stringent quality standards set by both federal and state public health agencies. They also contain a wealth of other information, including facts about where your water comes from and how we monitor quality across our system through thousands of tests performed on samples each year.
