An independent certification organization now has earned some recognition of its own.

Underwriters Laboratories, Northbrook, Ill., has become one of the first organizations approved by the U.S. Environmental Protection Agency to test for 28 contaminants in the EPA's third Unregulated Contaminant Monitoring Rule (UCMR 3). Contaminants can come from many sources, one of which is industrial waste.

Every five years, in accordance with the Safe Drinking Water Act, the EPA identifies a new list of contaminants that are suspected to occur in public water systems and may warrant regulation. The Unregulated Contaminant Monitoring program determines whether new regulations are needed to protect public health.

"The regulatory expertise and streamlined services we provide our customers build on the analyses we have done on more than 2.5 million water samples for thousands of bottlers, public water systems, engineering firms and state and federal agencies, such as the EPA," says Hank Lambert, general manager of UL Global Food and Water Businesses.

UL can test for more than 900 known contaminants.
