HWAAP-A04
BABBITT CLOSED LANDFILL
SITE DESCRIPTION
HWAAP-A04 is a closed unlined landfill located southeast of the Former Babbitt Housing Area and approximately 1 mile east of the base of the Wassuk  Mountain Range. The landfill covers 65 to 75 acres. The landfill was in operation from 1940 to 1975 and received office and domestic waste. The landfill was operated by the modified trench method, in which operators used sand and gravel to cover the solid waste material. Refuse was routinely burned in the landfill trenches. A geophysical survey was completed in 1994 to define the landfill area. The surveys identified anomalies which define the areas of the landfill where there appears to be buried material in linear trenches, consistent with historical data of the site. Field investigation showed buried material to be dry waste and construction debris. Three wells were installed in 1996 to sample groundwater. The groundwater sampling program at this site has been under way for one year. Groundwater monitoring is no longer required because contamination was not found.
The site was closed by collecting the surface debris, placing it in an existing depression and covering it with one foot of clean soil. The monitoring wells installed in 1997 were abandoned according to State of Nevada regulations. The Army plans to relinquish their easement for the landfill with a quick claim deed to Mineral County with a restricted covenant running with the land that no residential buildings, nurseries, hospitals, or child-care facilities are built on the landfill site.
PROPOSED PLAN
A Closure Decision Document was approved by the NDEP in November 2001.
