KINGMAN, Ariz. – The U.S. Army Corps of Engineers Los Angeles District is preparing for work at the Formerly Used Defense Site just outside of Kingman, Ariz.
The District has approved the Time Critical Removal Action for the former Skeet Range, which is referred to as Munitions Response Site 03 of the former Kingman Ground-to-Ground Gunnery Range. The site covers approximately 75 acres.
“Analysis of soil samples at this site found concentrations of polynuclear aromatic hydrocarbons (PAH) over 1,000 times higher than that allowable under 2007 Arizona residential risk-based screening levels,” wrote Fran Firouzi, the District’s project manager. “The surface soils of approximately 60 residential lots have been impacted by skeet fragments and PAHs.”
The District has already completed the site inspection. During the inspection, the District found the PAH levels in the area to be significantly higher than acceptable. Many of the lots have not been landscaped or modified, and they still show evidence of the clay pigeon shards used at the skeet range.
The contaminants are likely from fragments of clay pigeon debris leftover from the area being used as a skeet-shooting range during World War II. Firouzi and her team are in the process of completing letters to send to residents outlining the requests to enter the property for further testing and soil removal.
Work on the property involves sampling the soil on the properties identified by the study to see how much impact the PAHs have had. If the inspection warrants, the District could remove up to one foot of soil from properties and replace it with clean soil. The District will replace any surface grading, landscape or xeriscaping it removes during the course of the cleanup to try and match pre-work status.
