| EAST 67th STREET GROUND WATER PLUME | Odessa, Texas | |
| Ector, County |
Site Location:
The East 67th Street Groundwater Plume site consists of a contaminated
ground water plume originating from an unidentified source(s). The
ground water plume is situated in Ector County, adjacent to and
northwest of the city limits of Odessa, Texas, and the extent of the
plume has not yet been fully identified. The plume is centered in a
rural residential area, with some light industry, along East 67th Street
and Stevenson Street.
Site History:
The site was identified by the Texas Commission on Environmental Quality
(TCEQ) during routine monitoring of public water supplies. Contaminants
were first detected above background concentrations at one of the four
public supply wells at the DeVilla Mobile Home Park located on VFW Lane.
Further testing showed that 31 private drinking water wells within one
mile also contain contamination above background concentrations. Eight
of those have contaminant concentrations above Safe Drinking Water
Maximum Contaminant Levels (MCLs) or health based benchmarks.
Site Contamination/Contaminants:
The ground water plume contains tetrachloroethene (PCE), trichloroethene
(TCE) and cis 1,2-dichloroethene (cis-1,2-DCE). The site is being
evaluated as a ground water plume of PCE and TCE with no identified
source. Eight residential wells with concentrations of PCE above the MCL
have been identified. TCEQ is currently sampling these wells on a
quarterly basis. Sampling by EPA and TCEQ has not yet defined the outer
boundary of the plume. However, based on existing sample results, the
plume is at least 0.5 mile by 0.5 mile in size.
Potential Impacts on Surrounding Community/Environment:
There is no other potable water supply for the residents. The potable
water is in a relatively shallow aquifer (less than 70 -100 feet deep).
Response Activities (to date):
TCEQ installed granulated activated charcoal water filtration systems on
eight private wells. Currently TCEQ is providing operation and
maintenance on the filtration systems.
[The description of the site (release) is based on information available at the time the site was evaluated with the HRS. The description may change as additional information is gathered on the sources and extent of contamination. See 56 FR 5600, February 11, 1991, or subsequent FR notices.]
