Drinking water certifications
Our commitment to quality is reflected in our certification and audit record. UL is certified in 50 states and Puerto Rico, giving us the broadest set of certifications for drinking water analysis. We were also one of the first laboratories certified under the National Environmental Laboratory Accreditation Program (NELAP), a program that implements voluntary performance standards for the operation of environmental laboratories.
Each year our laboratory is audited by many organizations including the states in which we are certified, as well as the American National Standards Institute, U.S. Air Force, U.S. Army Center for Health Promotion and Preventative Medicine, and the United States Environmental Protection Agency.
