What you need for Find a Certified Laboratory for Water Testing
For a list of laboratories offering drinking water analytical services for private well owners and residential customers, see MassDEP Certified Laboratories Offering Analytical Services for Private Well Owners and Residential Customers.
If you are concerned about the quality of your drinking water, you can contact a MassDEP-certified laboratory to have your water tested.
Please note that:
- Your public water supplier is legally responsible for providing you with safe drinking water and for notifying you if there is a problem with your water supply.
- If you have a private water supply (a private well), your local Board of Health has jurisdiction over it. This may include local by-laws or regulations for periodic water testing at the well owner's expense.
- MassDEP does not test water for individuals.
- MassDEP strongly encourages the use of certified laboratories for testing private drinking water.

How to Use the Certified Labs Database
See the screenshot provided below.
- If you know the name of the lab, select it from the first drop-down menu at "Certified Lab Name."

Note that there may not be a lab within convenient driving distance of your location. However, many labs offer a mail-in service.
- If you want to have your water tested for a specific contaminant, in the box next to "Analyte" scroll to the name of the contaminant. For example, many people want their water tested for lead. Find "LEAD" on the list of analytes and select it.

More info for Find a Certified Laboratory for Water Testing
Please note that although the database includes both commercial and municipal laboratories, municipal water- and wastewater-treatment plant laboratories generally do not accept samples for analysis from private consumers other than local residents. Such samples should be submitted for analysis to a MassDEP-certified commercial laboratory or a MassDEP-certified municipal environmental public health laboratory.
