Linked to this page are individual regulatory Lead and Copper Rule results going back to 1992, when lead levels had already dropped by about 50%.
The results are presented with addresses eliminated to protect the individuals' privacy. Each volunteer who participated in the sampling program received his or her own individual results.
These individual results provide a snapshot of what is happening in a specific house when the water has sat stagnant. Because the sampling protocol is designed to evaluate the effectiveness of corrosion control, the results do not provide real information about the water a typical customer would typically drink.
We sample only the homes most likely to have any lead, and then sample that stagnant water most likely to have leached any lead. Most consumers do not actually consume that stagnant water.
To remove stagnant water from your home's system, and to reduce the potential of lead leaching into your tap water, run the faucet for about one minute, until the water turns noticably colder. Visit our What You Need to Know about Lead in Drinking Water page for more information.
If you have questions or would like more information about lead in drinking water, please call our Water Quality Hotline: 617-242-5323, or email Joshua Das, Project Manager, Public Health: email@example.com
