Description:  Underwriters Laboratories Inc. (UL) is a 100+ year-old not-for-profit organization dedicated to public safety.  The UL Drinking Water Laboratory, founded in 1986 as Environmental Health Laboratories, fulfills the mission of “Working for Safe and Healthy Water” by providing high quality testing services on drinking and other clean water samples for public water utilities, environmental and engineering consultants, industrial, residential, and governmental clients.  In the first twenty years the laboratory has been serving our customers, the staff in South Bend analyzed approximately one and a half million samples for thousands of public water supplies of all sizes throughout the United States.   The laboratory holds drinking water accreditations from the EPA, forty-eight States, and Puerto Rico. 


Division:    Environmental Sciences



Testing Services:  The UL Drinking Water Laboratory specializes in trace level analysis of drinking water and other clean water samples for SDWA compliance as well as pilot plant studies and source water protection.  We offer a broad range of services including microbiological, inorganic contaminants (IOCs: general chemistry and heavy metals), (SOCs: volatile and semi-volatile contaminants), dioxins, radionuclides, disinfection byproducts (DBPs), and special analytical services such as PPCPs and Taste and Odor.  In addition to established methods, the UL Drinking Water Laboratory research and development team can provide custom analytical services utilizing the latest technologies such as LC/MS/MS and GC/MS/MS.
