Circle K Stores Inc. has been actively managing the fallout from an estimated 86,000 gallons of unleaded gasoline released from an underground storage tank (UST) system at its 1910 N State Route 89 location in Chino Valley, AZ. According to a town council press release, which occurred over 18 days in January 2024, it was attributed to the failure of a submersible turbine pump component.
In an ongoing effort to transparently manage the situation, Circle K has to date provided several updates on its remediation actions. These include performing weekly testing of drinking water wells in the vicinity and initiating soil remediation measures overseen by the Arizona Department of Environmental Quality (ADEQ). The latest press release from February 28, 2025, cited by the town of Chino Valley, underscores that "to date NO AQUIFER CONTAMINATION has been detected," assuring the local community that the nearest town well, located over a mile away from the site, is not at risk.
To monitor the state of the aquifer, four wells have been drilled in the immediate vicinity. Circle K has made it a point to communicate their efforts and findings in a series of press releases and briefings, including a presentation to the town council that detailed analysis, monitoring, testing, reporting, and mitigation strategies. One can view these comprehensive presentations and accompanying materials by accessing the links provided by the town's informational page.
With the response to the incident under scrutiny, Circle K has committed to continue to provide bi-monthly updates on the soil remediation progress. The ADEQ has been equally forthcoming, with their official Public Information Officer available for questions, and they have been maintaining a consistent cycle of review of Circle K's actions, most recently confirming again the absence of threats to drinking water sources in the area, according to their July 26, 2024, press release.
