Chronology of Actions:
Skip to most recent action
- February 2002-January 2003, based on results of water samples collected from 228 wells, the approximate boundaries of the plume were identified as from the southern end of Echo Spring Lane to Tower Oaks Boulevard, and from Timber Hollow to east of Jones Road.
- October 17, 2002, attendees at a public meeting at Moore Elementary School were told that the state had installed filtration systems on 21 wells where PCE was detected above the maximum contaminant level.
- October 21-28, 2002, the state was granted access to additional properties within the plume zone. Samples were collected at 150 locations as part of the quarterly monitoring. Collected water samples showed contamination above the maximum contaminant levels in two wells. Filtration systems were installed on those two additional wells.
- October 28, 2002-January 2003, TCEQ added green sand filters, or shocked the wells with chlorine at four locations with filtration systems where there were well discoloration or odor problems.
- January 24, 2003, the water well driller section of the Texas Department of Licensing and Regulation notified all licensed drillers in Harris, Waller, Grimes, Ft. Bend, Brazoria, Galveston, Montgomery, San jacinto, Chambers, and Liberty counties, of more stringent well construction specifications for drilled wells within the Jones Road groundwater plume area. The well driller alert area is different from the current well test area and is defined as extending from south of Woodedge Dr. to Jones Road West, and from Possum Hollow to east of Jones Road. Any new wells within the area must be drilled to the Evangeline aquifer with a 3-inch larger borehole than the outside diameter of the casing, and pressure cemented to a depth of 400 feet from the land surface.
- January 31, 2003, TCEQ established an Internet web site to make information more quickly available to residents within the impacted area, and included a link to a map of the area covering the PCE plume, and also included an access agreement, form that may be printed out, filled in, and submitted by residents within the zone who have not yet granted access for testing of their wells. The mail address for submitting access agreements is:
P.O. Box 13087 - MC-142
Austin, Texas 78711-3087
- February 2003, a hazard ranking system (HRS) score was calculated for the Jones Road ground water plume site.
- February 13, 2003, Weston Solutions, Inc. reported tests were completed on 149 wells where owners have filed access agreements. For well owners within the sampling zone, who have not yet signed an access agreement, an electronic version may be printed out, signed and mailed to the project contact. For well owners who want to have their water independently tested, a list of certified water testing labs is provided.
- February 17, 2003, TCEQ staff attended a Harris County-sponsored public meeting at Matske School, 13102 Jones Road. Approximately 100 citizens, along with representatives of the U.S. Environmental Protection Agency, and staff from the Harris County Pollution Control and the Harris County Health Department, were in attendance.
- March 31, 2003, based on results of water samples collected from 149 wells, the approximate boundaries of the plumewere changed to:
- the northern boundary: south of Woodedge Dr. along Echo Spring
- the southern boundary: Jones Road West (near the intersection with Jones Road)
- the western boundary: west of Timber Hollow Dr. along Timber Crest
- the eastern boundary: one-sixth of a mile east of Jones Road
No additional wells were found to need a filtration system; the number of filtration systems installed remains at 24.
Six wells did have detections of tetrachloroethene below the maximum contaminant level of 5 parts per billion. During the past year of sampling, those wells with detections below the maximum contaminant level have remained below the maximum contaminant level.
No contamination was found in the nine wells sampled west of the main sampling area on Bexhill Dr., Dakar Dr., and Dermott Dr.
- March 31, 2003, results of the February well sampling analysis were mailed to well owners.
- April 11, 2003, two additional wells sampled during the February 2003 sampling event were found to have detections of tetrachloroethene, but below the maximum contaminant level of 5 parts per billion.
- April 30, 2003, the Environmental Protection Agency published a legal notice in the Federal Register, proposing the Jones Road groundwater plume site to the National Priorities List. The text of the legal notice may be viewed or downloaded from this TCEQ Superfund web site. The steps in the Superfund process are explained in the attached drawing.
- May 19-23, 2003. Weston Solutions, Inc. reported tests were completed on 146 wells where owners have filed access agreements. For well owners within the sampling zone, who have not yet signed an access agreement, an electronic version may be printed out, signed and mailed to the project contact. For well owners who want to have their water independently tested, a list of certified water testing labs is provided.
- June 16, 2003, TCEQ and Harris County, along with the U.S. EPA, conducted a community meeting at Matzke School, 13102 Jones Road, Houston, beginning at 7 p.m. to provide an update on the site and to answer questions and address concerns.
- July 7, 2003, in response to requests from the community, the repository files were moved from the Collier Branch Library in Houston to the Northwest Harris County Library at 11355 Regency Green Drive.
- July 31, 2003, the results of the May 2003 sampling event did not show the need for any additional filtration systems at the current time. Based on results of the water samples collected from 146 wells, the appropriate boundaries of the plume were identified as:
- the northern boundary: Woodedge Drive
- the southern boundary: Neeshaw Drive
- the western boundary: Timber Hollow Drive
- the eastern boundary: one-sixth of a mile east of Jones Road
- August 4, 2003, TCEQ began quarterly sampling of 108 wells. Thirty-eight wells showed no contamination for four consecutive samplings, and were qualified to be dropped from further sampling at this time. The basis for dropping a well is that there is no detection of contaminants and that there is a clean well between it and the wells that show contamination within the groundwater plume boundary.
- August 25, 2003, field activities began for the first phase of the remedial investigation. Thirty-seven cone penetrometer (CPT) test borings and three monitor wells were installed during a two week period. Groundwater and soil samples were collected.

- September 23, 2003, results from the August 2003 sampling event showed one additional well with detection above the maximum contaminant level. This well was within the boundary of the plume and had not been sampled previously. The wells with prior detections below the maximum contaminant level have remained below the maximum contaminant level.
- September 29, 2003, a legal notice was published by EPA in the Federal Register (68 FedReg 55875-55882), finalizing the listing of the Jones Road Ground Water Plume site on the National Priorities List. The contents of the final rule may be viewed or downloaded from this TCEQ Superfund web site. EPA's response to public comments received on the proposal of the Jones Road Ground Water Plume to the National Priority List has been abstracted from a document containing responses to comments on five sites. The response to comments,in Adobe Acrobat portable document format, may be viewed or downloaded from this TCEQ Superfund web site.

- May 31, 2004, preliminary analytical data from the May quarterly monitoring event revealed that the concentrations of PCE were above the maximum concentration level of 5.0 parts per billion in two additional residential wells. One owner refused the installation of a filtration system. The other well was fitted with an activated carbon filtration system.
