/> In accordance with the Environmental Protection Agency's (EPA) Drinking Water Laboratory Certification Program, states assume primacy for enforcing the Safe Drinking Water Act (SDWA) and are responsible for certifying laboratories that conduct analyses against the requirements of this Act. Each state maintains a certification program that requires laboratories to successfully analyze designated testing samples, demonstrate approved methods, and pass periodic inspections.

UL is proud to be the first and only laboratory certified to provide water testing services in all 50 states and Puerto Rico, said Hank Lambert, general manager of UL Global Food and Water Businesses. The breadth of our state certifications speaks to the unmatched quality of our analytical services. We are now able to provide Public Water Systems (PWS) across the U.S. with what we feel is an unmatched experience in analytical expertise and customer service.

A recognized leader in SDWA compliance and emerging contaminant testing for more than two decades, UL has analyzed more than 2.5 million drinking water samples for thousands of public and private entities, including the U.S. EPA. In addition to being certified in all 50 states and Puerto Rico, the company is accredited by the American National Standards Institute (ANSI) to certify water products. UL is also an approved certifier of water products that meet the criteria of the EPA's WaterSenseSM program, which identifies and promotes the use of water-efficient products.
