Drinking Water Quality Testing

Testing, inspection and certification services for materials, products and innovative technologies that deliver drinking water from source to tap. 

Meeting the needs of the drinking water industry

Access to potable water is essential, and all water-contacting materials and products, from the water source to the tap, must undergo thorough evaluation to help prevent harmful chemicals, metals and microorganisms from contaminating the water we drink. UL Solutions offers a broad range of comprehensive services to test, inspect and certify the essential materials, products and technologies that deliver water.
