ECBC completes monitoring at Umatilla chemical facility

The U.S. Army Edgewood Chemical Biological Center announced on Wednesday that it has safely sampled, monitored and analyzed the 58 hazardous waste units at the Umatilla Chemical Agent Disposal Facility.

Chemical Biological Applications and Risk Reduction worked at Umatilla until the contract was switched to Chemical Materials Activity. CBARR was able to continue working at the site because of an unique Cooperative Research and Development Agreement with the site contractor.

The process CBARR used included platforms able to assess the conditions inside the various structures. Mustard Igloos Temperature Conditioning Systems were used on igloos on the sites.

"MITECs are big heaters that are staged inside the igloo," Satchell Doyle, CBARR chemical engineer and Umatilla project manager, said. "They heat the inside of the structure to at least 80 degrees. Two [Real-time Analytical Platform] operators then use the [Depot Area Air Monitoring Systems] and [Miniature Continuous Air Monitors] to monitor the atmosphere to make sure it is not hazardous. After 12 hours at 80 degrees Fahrenheit, a sample is collected shipped back to ECBC at Aberdeen Proving Ground, Md., where CBARR conducts [General Population Limit] analysis."

CBARR took samples from numerous sites to test and survey the various igloos, six of which were contaminated with waste items that were eventually shipped to Port Arthur, Texas.

"If we were going to use these RTAPs anywhere else, what would I need?" Aaron Sredin, CBARR chemical engineering technician, said. "I pulled out every item that I deemed necessary for each of the six instruments that we were using inside three RTAPs onsite. I categorized everything from quantity to part number."
