Environmental Laboratory Certification Program (ELCP)

The Environmental Laboratory Certification Program (ELCP) registers and approves all environmental laboratories (private, municipal, and industrial non-commercial) granting certification for testing of drinking water, wastewater, sewage, solid waste, soils, and other environmental samples for microbiologicals, inorganics, organics, and radiochemicals. The authority for this function is found in the Connecticut General Statues Sections 19a-29a and 25-40 and Public Health Code Regulations 19-4-1; 19a-36-a25 through A33; and 19a-36-A57 through A63. The ELCP office also enforces U.S. Environmental Protection Agency regulations involving environmental laboratory testing (the Safe Drinking Water Act, the Clean Water Act and the Resource Conservation and Recovery Act). The Environmental Laboratory Certification Program mission is to promote the benchmark by which accurate, precise, and legally defensible analytical data is reported by the environmental laboratory industry for use in compliance and in accordance with federal and state law.  This is accomplished by ensuring that environmental laboratories located in or doing business in CT meet all applicable EPA and CT standards.
