Laboratories Certified for Lead Analysis
in Drinking Water

Massachusetts Water Resources Authority


If you're interested in checking to see if lead is leaching from your household plumbing into your home's tap water, you should get your water tested. Below is a list of labs that are DEP Certified to test household tap water for lead. Visit the DEP web site for more information and a searchable database of labs.

How to Take a Tap Water Sample for Testing

MWRA recommends taking samples from the kitchen's cold water faucet.

The first sample should be taken in a manner similar to what is recommended by EPA regulation. This includes sampling the "first flush" of water that has been standing dormant (unused) for six or more hours, usually overnight. This first flush sample tests the worst-case scenario of the water and determines how much lead may be leaching from your household plumbing.

The second sample is more representative of your daily water use, and should be taken after running the faucet. MWRA recommends taking the second sample after running the faucet for two minutes or after normal water use in the morning.

If you have any questions, please call the MWRA Water Quality Hotline: (617) 242-5323, or contact your local water department.
