Site Remediation Continues

On-going activities:

  • Continued the application of water for dust control;
  • Continued the application of foam and BioSolve for Total Volatile Organic Compounds (TVOC), Particulate Matter (PM-10) [dust], and odor control;
  • Maintained erosion and sediment (E&S) controls (Installed waddles - wood chip and straw filled fabric tubes - around the Site perimeter to prevent silt and sediment from leaving the Site and covered all stockpiles);
  • Continued pumping from the decontamination pads, excavated areas, sumps and dewatering wells to the water treatment plant (WTP);
  • Continued operation of the WTP and discharge to the sewer;
