ADEQ has completed the Feasibility Study (FS) Report for the Klondyke Tailings Project Water Quality Assurance Revolving Fund (WQARF) site in Graham County, Arizona. The FS Report proposes a remedy that addresses contaminated soil at the site in a manner that achieves compliance with Arizona Revised Statute §49-152 and Arizona Administrative Code R18-7-2 and will achieve the remedial objectives for the use of the affected properties.
The Klondyke Tailings Project WQARF site is located within Graham County, two miles north of the town of Klondyke, in Section 6, Township 7 South, and Range 20 East. The site boundary is defined by the extent of soil contamination above the residential soil remediation level for lead of 400 milligrams per kilogram. The site boundary is irregular and includes property containing tailings piles and several surrounding properties.
Contaminants of concern at the site are antimony, arsenic, cadmium, copper, lead, manganese, mercury and zinc.
