LUSTs – Arizona Proactively Minimizing the Threat to Environmental Health and Safety

March 20, 2017

According to the U.S. EPA, approximately 561,000 underground storage tanks (USTs) nationwide store petroleum or hazardous substances. The greatest potential threat from a leaking UST (LUST) is contamination of groundwater, the source of drinking water for nearly half of all Americans. EPA, states, and tribes work in partnership with industry to protect the environment and human health from potential releases.

Randy Bauer, a project director with SCS Engineers in Arizona stated, “We have seen a significant increase in the number of storage tank failures nationwide, primarily from single-walled fiberglass tanks installed in the 1990s.” He went on to say, “Some fuel additives, such as ethanol, are known to eventually dissolve the epoxy used in the fiberglass tanks, leading to cracks and failures.”

SCS currently has seven soil and groundwater remediation systems in operation in Arizona because the Arizona Department of Environmental Quality (ADEQ) has a proactive program. As the state’s environmental regulatory agency under the Environmental Quality Act of 1986, ADEQ is a separate, cabinet-level agency that directs all of Arizona’s environmental protection programs. Their mission is to protect and enhance public health and the environment in Arizona. The department does this by overseeing the state’s environmental laws and authorized federal programs to prevent pollution of the air, water, and land, and to ensure clean up of pollution, such as LUSTs when it occurs.
