In late September 2006, the U.S. Environmental Protection Agency (EPA) began the removal clean up at the Helena Chemical Company facility (site) in Mission, Texas. The removal action involves digging up the contaminated soil within the on-site facility property underneath a deteriorating asphalt cap.
As of April 30, 2007 EPA has excavated and stockpiled approximately 13,300 cubic yards of soil for further analysis and waste characterization. To date, EPA has removed approximately 13,300 cubic yards of contaminated soil and 39,254 gallons of storm water for off site transportation and disposal.
All heavy equipment used for the removal activities has been decontaminated for mobilization from the site.
As of April 30, 2007 a total of 845 particulate and gaseous phase air samples, 182 confirmation of cleanup soil samples, 6 backfill source soil samples, 4 sludge/sediment samples, and 2 water samples have been collected and submitted to a fixed laboratory for analysis. All pesticide particulate and vapors levels on-site and in the surrounding community have been below the site-specific action levels.
An EPA community office trailer is available on Site. A map which will have updated daily information on particulate air monitoring data is being posted next to the entrance of the office trailer for the public to stop by and view. This information will also be available in hard copy and electronic format. The office is open to allow community members an opportunity to speak with an EPA representative in person about any questions or concerns they may have about ongoing Site activities. This office has up to date and current information available in both English and Spanish.
