Jones Road Site Description
The Jones Road site is a groundwater plume contaminated with tetrachloroethylene (PCE) from the former Bell Dry Cleaners at 11600 Jones Road and other potential sources. PCE is a manufactured chemical that is widely used for dry cleaning of fabrics. The plume is documented to extend from the southern end of Echo Spring Lane to Tower Oaks Boulevard and from Timber Hollow to the eastern side of Jones Road.
Two hundred thirty one water wells have been sampled by the Texas Commission on Environmental Quality since February 2002. Not all of the sampled wells are used for drinking water. Approximately 150 wells are being sampled every three months by the commission in an effort to protect human health at the site.
The sampling area is larger than the known contamination plume, and includes wells with state-supplied filtration systems where confirmed contamination concentrations were above five parts per billion. A chart, illustrating parts per billion, in Adobe Acrobat portable document format, may be viewed or downloaded from this TCEQ web site.The five parts per billion is the maximum contaminant level of PCE allowed by the U.S. Environmental Protection Agency (EPA). Wells with PCE below the maximum contaminant level and wells located outside the area of confirmed contamination are included in the quarterly sampling to assist investigators as they watch for changes in the test readings.
The site has been proposed to the federal Superfund program National Priorities List. An EPA booklet provides guidelines to ensure household well water is safe. A reproduction of the booklet in Adobe Acrobat portable document format, may be viewed or downloaded from this TCEQ Web site.
