CIRCLE COURT GROUND WATER Willow Park, Texas

PLUME Parker County

(?) Site Location:

The Circle Court Ground Water site is a trichloroethene (TCE) ground water plume in the Trinity Aquifer, parts of
which are located within the city of Willow Park and the city of Hudson Oaks in Parker County, Texas. The source of
the plume has not been determined. The site plume currently extends approximately one-half mile along Russell Road.

xl Site History:

The site was identified by the Texas Commission on Environmental Quality (TCEQ) in 2006 during routine sampling
of a Public Water System (PWS) well that is owned and operated by the city of Willow Park PWS. Concentrations of
ground water samples collected from the well found TCE to be above the Safe Drinking Water Act maximum
contaminant level (MCL). The well was temporarily shut down. The city of Willow Park PWS installed a granular
activated carbon filter to remove TCE from the water pumped from the well. The well was then put back into service.
The TCEQ conducted a Preliminary Assessment (PA) in 2009 and a Site Inspection (SI) and Expanded Site Inspection
(ESI) in 2010 to characterize the plume and to identify possible sources of the TCE contamination.

1 Site Contamination/Contaminants:	

When the ESI was conducted in June 2010, no sources of contamination were identified. However, high
concentrations of TCE were found in the wells.
