In the United States, there are over 500,000 active underground storage tanks (USTs) that store petroleum or hazardous substances, and about 62,000 leaking UST sites that need cleaning up today. The greatest potential threat from a leaking UST is the contamination for ground water, which serves as the source of drinking water for nearly half the population in the United States. Given the proximity of these leaking USTs to water supplies, it is important for small drinking water systems to understand where the leaking UST sites are to protect the water supply and to understand the water demands in proximity to the leaking underground storage tanks. This is especially needed where ground water wells are located on the property for the tank facilities. EPA developed the first national database and application (UST Finder ) on underground storage tanks, a user-friendly tool that provides the needed geospatial data for these tank facilities and source water protection areas.

There are 242 small communities in remote and rugged locations not connected to Puerto Rico Aqueduct and Sewer Authority (PRASA) for their drinking water. This research seeks to develop, install, evaluate, and monitor affordable and sustainable treatment technologies to support non-PRASA systems achieving regulatory compliance. Over the past 14 years, substantial improvements have been made and EPA’s most recent upgrades from May 2021 are showcased in this presentation. Presented by Daniel Williams and Page Jordan, EPA's Office of Research and Development About the Presenters: Daniel Williams is a Physical Scientist with EPA’s Office of Research and Development, Center for Environmental Solutions and Emergency Response. He has a B.S. in environmental science from University of Cincinnati in Ohio. Since joining EPA in 2001, his research has focused on the development of pilot design, fabrication and installation. Daniel has been awarded a patent for his Portable Evaluation Pilot Skid (PEPS). Page Jordan is a Physical Scientist with EPA’s Office of Research and Development, Center for Environmental Solutions and Emergency Response. She received her B.S. and M.S. in environmental science from Miami University in Ohio. Her research focuses on chemical and microbial contamination in drinking and storm waters. Who Should Attend?
