Availability Session
EPA will hold an Availability Session on August 9,
2012, from 5-8 p.m. with a presentation at 6:30 p.m.
The Availability Session will be held at the
Community Center, 101 Stagecoach Trail, Willow
Park, TX 76087.
Background information
The Circle Court Ground Water Plume Site is a
trichloroethene (TCE) ground water plume in the
Trinity aquifer, parts of which are within the City of
Willow Park and the City of Hudson Oaks, in Parker
County, Texas. The source of the TCE in ground
water has not been determined. The TCE
contamination is present south of Interstate 20 along a
one-half mile section of Russell Road. The highest
concentration exceeding the Safe Drinking Water Act
maximum contaminant level (MCL) is present at
Circle Drive and Russell Road. The plume boundary
in the attached site map is estimated by the detection
of TCE in water samples collected from private and
public water supply wells. The ground water samples
are from the shallow aquifer at an approximate depth
of 100 to 250 feet deep. A site investigation has not
been started to determine the complete nature and
extent of contamination in the Trinity aquifer.
The TCE contamination was first identified by the
Texas Commission on Environmental Quality
(TCEQ) during routine sampling of the City of
Willow Park public water supply system. The ground
water contamination was detected in a public water
supply well at the Willow Springs Oaks Pump Station
located at 117 Circle Court in Willow Park (see map).
July 2012
The water supply well was shut down and the City
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 of the
site area in 2009, and conducted a site inspection and
expanded site inspection in 2010 to characterize the
plume and identify possible sources of the TCE
contamination. Water samples collected and analyzed
from supply wells in March and June of 2010 resulted
in seven wells with documented levels of TCE.
Superfund National Priorities List
The Circle Court Site was proposed to the National
Priorities List (NPL) of Superfund Sites in March
2012. EPA accepted comments on the proposed
listing until May 2012. A decision on a final listing of
the Site to the NPL is under review. The identification
of a Site for the NPL is intended to guide EPA in
determining which sites warrant further investigation,
and identify what remedial actions may be
appropriate. The State of Texas referred the site to the
EPA for NPL listing and potential remedial activities.
Since the source of TCE has not yet been identified
and controlled, the plume may continue to
contaminate surrounding water supply wells. Other
Federal and State cleanup programs were evaluated
but are not viable at this time.
Current status
The EPA has begun development of plans for the site
investigation as well as the collection of additional
information to evaluate potential source areas.
The TCEQ has installed and maintains a granular
activated carbon filter for a private well which
exceeds the drinking water limit for TCE.
