Maine Laboratory Accreditation

In Maine, laboratory accreditation is required by several regulatory programs including drinking water, waste water, and diesel residual organics/gasoline residual organics. Laboratories are accredited by the test (examples: Arsenic, Bacteria, Radon), so it is necessary to check with a laboratory to find out what they are accredited to test for. The tests which laboratories are able to do can change regularly. You may confirm what tests are done by a laboratory or ask any other questions regarding laboratory quality by contacting Laboratory Accreditation Officer Christine Blais:  Email or phone (207) 287-3220.
