ERH Update – October 29, 2018:

ERH treatment system operating measures as of October 22, 2018:

  • Average subsurface temperature was 99.6º C with a peak of 115.0º C.
  • The ERH system has applied 100% of the estimated 8,255,000 kWh of energy needed for treatment.  Additional operation will be required to reach ERH system goals.
  • The estimated TCE removal to-date is 5,329 pounds.
  • The perimeter air monitoring system has shown no TCE emissions at the perimeter of the site. The air monitoring results will be available on EPA’s website at

Please note that you may see occasional steam from the thermal treatment unit during system operation.  This is normal water condensation caused by weather conditions, and not a release of TCE vapor.
