Commercial Environmental Laboratory Mapping Application (CELMapp)

The CELMapp application can be used to search for all commercial environmental laboratories that are certified by the South Carolina Department of Health and Environmental Control's (DHEC) Office of Environmental Laboratory Certification. Listings found with CELMapp are general and do not specify parameters, methods, or analytes a certified laboratory may use. Analytes are the chemical substances in a sample to be analyzed.
