Ione Airport Kwik Stop Groundwater Monitoring

The Ione Airport Kwik Stop site is located on the northwest corner of the intersection of State Route 31 and Greenhouse and Dewitt Roads, south of Ione, Washington. The results of the previous site characterization, remedial investigation and groundwater monitoring efforts indicate a plume of petroleum-contaminated groundwater (gasoline) is present in the shallow, unconfined aquifer beneath the site, extending from the Airport Kwik Stop property, downgradient to undeveloped property located in the vicinity of the former Cabin Grill Restaurant property.

A soil vapor extraction system was installed at the Airport Kwik Stop in November 2012 as an interim action to address petroleum contamination in the soil. The system was also intended to reduce potential threats to downgradient domestic wells and the Pend Oreille River. The Environmental Assessment Program is conducting quarterly groundwater monitoring from 19 monitoring wells and seven domestic wells. All field and laboratory analytical data will be used to evaluate groundwater conditions and support decisions about the need for future remedial action under the Model Toxics Control Act.
