The County agreed to pay penalties of $4,600 for failing to maintain release detection records on three tanks between March and December 2007. The EPA also found that the county never performed automatic leak detection tests on two of the underground tanks between 2004 and 2007. Additionally, the EPA charged that county didn’t perform required line tightness testing on two of the underground storage tanks for 7 months in 2006 and 2007.

As part of its settlement with the EPA, Frederick County also agreed to install a $22,500 leak monitoring system on its above-ground tanks. According to the EPA, Frederick County will install the automatic tank monitoring system on one 12,000-gallon tank and 2 6,000-gallon tanks. The monitoring system will tie into a dedicated computer with software designed to track any fuel releases. Reliable monitoring of tanks, whether above ground or underground, leads to quicker and more efficient responses in the event of an accidental leak.

According to the EPA, the county “neither admitted nor denied liability for the alleged violations, but certified its compliance with applicable UST regulations. The settlement reflects the county’s cooperation with EPA’s investigation, and good faith compliance efforts.”

“With millions of gallons of gasoline, oil, and other petroleum products stored in USTs throughout the U.S., leaking tanks are a major source of soil and groundwater contamination,” the EPA said in a statement about the settlement.

“EPA and state UST regulations are designed to reduce the risk of underground leaks and to promptly detect and properly address leaks which do occur, thus minimizing environmental harm and avoiding the costs of major cleanups,” the agency said.

At first the Trauds assumed the water’s bad odor and taste came from being unused, so they gave it the benefit of the doubt and waited a couple of weeks. To their surprise, the problem only grew worse.

The only apparent solution was to have the water tested by a lab, which cost the Trauds a few hundred dollars. When the results were in, the lab contacted David Traud and advised him not to use the water because it contained gasoline components. David called Holli, who was staying with family in North Carolina with their newborn son, and told her to remain where she was.

In the following weeks, the Trauds’ neighbors, David and Irene Mullins, also noticed a problem with the water from their well. Tests from Virginia’s Department of Environmental Quality confirmed that both wells were “severely impacted” by fuel that had been leaking from an underground storage tank at the old gas station. Worse, the leak had been detected more than 10 years ago.

DEQ geologist Todd Pitsenberger told News & Arts that his agency tested the land around the buried tanks back in 1998 and concluded that “the release was relatively minor.” The DEQ took no action because there were no springs or wells in the immediate vicinity.

So when the Trauds built their home in 2007, the county health department issued permits for the construction of wells, unaware that the land was contaminated.

The UST leak, which county officials presumed to be small and relatively harmless, damaged the surrounding environment so severely that the Trauds and their neighbors still can’t drink their tap water. The DEQ installed filtration systems that make the water suitable for washing, but it is still not potable. The agency plans to install new wells this summer.

Cleanup of the site is expected to cost approximately $81,000, a small cost compared to the time, money, and aggravation the Trauds and their neighbors have endured, not to mention the health risks that exposure to fuel-contaminated water can cause.

Geologist Pitsenberger told the News & Arts that underground storage tanks are a big problem in this country. “They started putting tanks in the ground back in the ‘40s and ‘50s, and nobody really thought ‘These things are going to leak.’” In the 80s, however, the Environmental Protection Agency realized that the tanks did leak and that hundreds of thousands of them lay buried in the soil throughout the country, compromising both the health of the environment and the humans who consumed the contaminated water.
