Alexander Farms
 SITE DESCRIPTION
In
April 1998, Ecology responded to complaints of yellow water coming from two
domestic wells in the vicinity of the Alexander Farms site. Ecology determined
that the soil and groundwater at the site was contaminated with Dinoseb, a
herbicide that was banned from use by the USEPA in 1986. Between 1998 and 2005,
approximately 15,000 tons of Dinoseb contaminated soil was excavated from the
site. The soil, which was acting as the source of groundwater contamination, was
hauled to a licensed disposal facility. Between 2005 and 2008, 14 groundwater
monitoring wells were sampled quarterly and analyzed until the groundwater in
all the wells remained below cleanup levels for Dinoseb for eight consecutive
quarters (2 years). As of January 2008, the groundwater from all 14 wells had
tested below cleanup levels for two years. Based upon review of the Cleanup
Action Reports and eleven years of data, Ecology has determined the site is no
longer a threat to human health and the environment.
