Kum & Go workers in Centerville discovered Wednesday morning that gasoline had leaked from one of their tanks in the last couple of days, according to Iowa DNR.
Although local officials have not detected any free product or vapor in city sewer systems, residents near the station should call 911 if they smell gasoline in their basements.
Gasoline was delivered to the Kum & Go at 830 N. 18th St. Monday night. An estimated 3,000 gallons of gasoline have leaked from the tank.
An environmental contractor is on site to check sewers for vapors and free products. They will likely dig a recovery trench or sump pit to recover the gasoline.
The leak was reported to the DNR early Wednesday afternoon. The DNR will continue to monitor the situation.
