PUBLIC HEALTH ASSESSMENT

ODESSA SUPER SITE
(a/k/a SPRAGUE ROAD GROUND WATER PLUME)
ECTOR, ECTOR COUNTY, TEXAS

CONCLUSIONS

  1. The Sprague Road Groundwater Plume site currently poses a public health hazard because elevated levels of chromium have been detected in groundwater and some individuals continue to use the water for drinking and other potable purposes. In the absence of remediation, the groundwater plume potentially could spread to other private domestic wells, putting additional people at risk.
  2. Contaminated surface soil at Leigh Metal Plating presents a potential public health hazard since access to the site is not entirely restricted.
  3. The five foot deep pit at National Chromium Corporation presents a physical hazard to children who may trespass on the site.

PUBLIC HEALTH ACTION PLAN

Actions Planned

  1. TDH will evaluate any new groundwater data as it becomes available.

Actions Recommended

  1. People who have well water with chromium above the maximum contaminant level of 0.1 mg/L should switch to an alternate water source for drinking and cooking.
  2. Further restrict access to contaminated areas at Leigh Metal Plating.
  3. Restrict access to the National Chromium Corporation site to prevent possible injury from the site's physical hazards.
