Maine Laboratory Certification

In Maine, laboratory certification is required by several regulatory programs including drinking water, waste water and diesel residual organics/gasoline residual organics. Laboratories are certified by test (examples: Arsenic, Bacteria, Radon), so it is necessary to check with a laboratory to find out exactly what they are certified 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 calling (207) 287-1929 or by emailing the certification officer at

The Maine Laboratory Certification Program has reduced lab certification fees. The current laboratory certification rules, adopted in April 2010, included a significant fee structure change. With the rule in effect for two years, it has become clear that fees are greater than necessary to support the current laboratory certification program. An interim change in the fee structure has been adopted prior to the formal rule making process which is currently scheduled for the fall of 2012. The fee structure change has been incorporated into these lab certifications applications: Application (doc file), Application (pdf file)
