Certified Laboratories

The Kentucky Laboratory Certification Program is administered by the Kentucky Energy and Environment Cabinet. Laboratories must be certified prior to analyzing public drinking water samples.

The Division of Water (DOW) certifies laboratories (located both in-state and out-of-state) annually for chemistry, microbiology, radionuclides and Cryptosporidium analyses. DOW performs on-site audits at least once every three years for in-state certified laboratories.  Out-of-state laboratory certification is available through reciprocity with certification by an equivalent certifying authority. DOW's certification program regulatory authority is based on 401 KAR 8:040, which incorporates U. S. Environmental Protection Agency (EPA) requirements for laboratories performing  drinking water analyses.

A complete list of EPA-approved test methods can be found in 40 CFR 141 (National Primary Drinking Water Regulations). Complete method text can be found in either 40 CFR 141, Standard Methods (editions 18, 19 and 20), other consensus programs and/or the EPA web site. For Kentucky public drinking water analyses, all test methods must be approved by EPA and DOW.

DOW administers the laboratory certification program for laboratories performing drinking water analyses. The DOW Laboratory Certification Officer is Patrick Garrity, who may be contacted at 502-564-3410 or by e-mail at The cabinet contracts a microbiology third-party auditor who works under the direction of the Laboratory Certification Program Manager.  Final microbiology certification decisions are made by the DOW Laboratory Certification Officer.

EPA's Laboratory Certification web site provides information about the Drinking Water Laboratory Certification program. The EPA Labcert Bulletin is also available here.
