Whirlpool to use chemical oxidation to remove TCE

City Wire (AR)
July 2, 2013

A document received by the Arkansas Department of Environmental  
Quality from consultants on behalf of Whirlpool details the company's  
plan to deploy chemicals to treat the trichloroethylene (TCE) on the  
company's former manufacturing site and in a neighborhood north of  
the site that sits on a toxic plume.

The letter, from ENVIRON Corp., said that "pilot studies" shows that  
chemical oxidation reduced the concentrations of TCE in groundwater.  
The plan, previously reported by The City Wire [1], is not new,  
though it is explained in more detail in a letter dated June 14.  
Though previously mentioned in a May 21 revised risk management plan,  
ENVIRON had not fully-detailed how the plan would work.

"The science is sound and the approach is a proven remedy," the  
letter reads. "There are many sites in the U.S. and Canada that use  
focused / targeted chemical oxidation to enhance the overall  
performance of natural attenuation by reducing significant mass in  
target areas. We are confident this approach is the best solution  
given the existing understanding of the site and current land uses."
