KINGMAN, Ariz. -- The U.S. Army Corps of Engineers Los Angeles District hosted an open house Aug. 20 to discuss an upcoming remedial investigation and feasibility study of a former ground-to-ground gunnery range.
The Corps is the lead federal agency on the study.
During the meeting, the agency’s representatives updated the public on the process, which requires access to properties and parcels within the area of the study.
The Corps must obtain a signed right-of-entry document from property owners to take soil samples to test for debris and contamination – possible remnants from the breakdown of clay pigeons used at the World War II gunnery range. At that time, the clay pigeons were constructed with coal tar pitch, which contains chemicals known as Polycyclic Aromatic Hydrocarbons, or PAHs, now a known carcinogen.
"We've sent 158 (right-of-entry) letters this phase," said Steve Winkleblech, District realty specialist. "To date, 63 (right of entries) have been signed, and we've had no response from 60 property owners."
The site includes about 284 residential properties and parcels, located on Tommie Drive, East Packard, Lass, East Snavely, East Thompson, East Lum, East Ryan, East Hearne, East Devlin, East Shaeffer, East John L and Northfield avenues.
In all, 55 properties and parcels were cleaned between April 2013 and July 2014.
The remedial investigation and feasibility study will determine if additional clearance activities are necessary.
"If remedial action is required, a second (right of entry) must be signed by the property owner to allow the Corps or its contractors access for cleanup," Winkleblech added.
