Lead Test Results

If you are a private well owner and not served by Connecticut Water, we have the found the website of the Eastern Highlands Health District to be a good source of information. The State of Connecticut Department of Public Health also has a web page for private well owners.


Lead in Drinking Water

The importance of what our water professionals do every day is more evident these days with the recent media coverage of the water quality crisis in Flint, Michigan. We know customers may have questions and we want to assure you that we take a number of steps in our water treatment and testing so you can have confidence in your water quality. Our Lead in Drinking Water Factsheet provides answers to commonly asked questions about Lead in Drinking Water

You should know lead is rarely found in surface water (lakes,streams) and groundwater (aquifers, wells). Connecticut Water conducts extensive water quality testing at our sources and within our distribution system and no lead has been detected. The primary way lead can enter drinking water is when it comes in contact with lead service lines or household plumbing(pipes, faucets) made from lead.

A critical step in reducing the risk of lead leaching from customers’ service line or internal plumbing is to adjust the pH in the water system. We have a comprehensive corrosion control program that provides treatment based on the source water quality. Further, we fully comply with the EPA requirements regarding sampling for lead in drinking water and have provided documentation to the Connecticut Department of Public Health to demonstrate our results.
