Our Certifications

Babcock Laboratories was one of the first laboratories in the State of California to receive certification by the California Department of Public Health (CDPH) for the analysis of drinking water for public health protection. Since that initial certification, our accreditation has never lapsed. Today, our certifications include not only the microbiology of drinking water and wastewater, but also the complete inorganic and organic analysis of drinking water, wastewater, groundwater, soils and hazardous materials. 

Babcock Labs is approved for the testing of drinking water, wastewater, groundwater, soils and hazardous waste in the following fields: Bacteriology, Inorganic Chemistry, Toxic Chemical Elements, Organic Chemistry, and Extraction Tests.
