7/27/2023 - CT Water: A Precautionary Boil Advisory Has Been Lifted

Connecticut Water issued following update on Friday, July 28, 2:15pm.

The precautionary boil advisory previously issued for customers in Terryville, Thomaston, Southbury, Middlebury and Oxford has been lifted. You may resume normal use of your water for all purposes including drinking.

Additional water quality tests have confirmed that your water meets all state and federal drinking water quality standards and that bacteria is NOT present.

We apologize for the inconvenience of the precautionary boil advisory. Your health and safety is our first priority and we are committed to being transparent with you.

Sometimes, factors in the collection, transportation, and testing of water samples can cause false positive results. That’s why we conduct hundreds of tests each day throughout our water systems from source to tap.

Because testing anomalies can happen, state regulations do not require water systems to notify customers until a second bacteria test confirms that bacteria was present. For the safety of our customers and in an abundance of caution, we choose to notify you at the first test. If additional samples show it wasn’t present, we have caused you an inconvenience but we have prioritized your health by sharing information as soon as we have it.

In this case, samples confirmed that the initial bacteria result was an anomaly and that your water did, and continues to, meet all safe drinking water standards.

We thank you for your patience and for putting your trust in us.



Connecticut Water issued following statement on Thursday, July 27, 3:50pm.

We have issued a precautionary boil water advisory for customers in the Heritage Village Water System (Southbury, Oxford, and parts of Middlebury) due to a water quality test that indicated the presence of bacteria.

We encourage customers to boil their tap water as a precaution before using it for drinking, cooking, food preparation, reconstituting baby formula or using for any purpose where it will be consumed. Customers may also use bottled water for these purposes until the boil water advisory has been lifted.

The water can be used without boiling for bathing, cleaning, sanitation or other purposes where the water is not consumed.

The precautionary boil advisory will remain in effect until we collect water samples and test in a state-certified laboratory to confirm that the water is free from bacteria and can be used as normal.

We expect to receive these results within 48 hours. We will notify you as soon as we have results.

We apologize for the inconvenience and thank you for your patience as we work to ensure the quality of your water.
