FORT SMITH, Arkansas — Chemical injections this year at the former Whirpool Corp. facility in western Arkansas decreased groundwater contamination levels, the company said its latest quarterly report.
Whirlpool's former plant in Fort Smith used trichloroethylene, known as TCE, as a degreasing solvent from the late 1960s through the early 1980s. The chemical is now known to be linked to increased cancer risk.
The Arkansas Department of Environmental Quality approved a cleanup plan for Whirlpool in December to address the chemical in groundwater and soil, the Times Record (http://bit.ly/1uWH0mi ) reported.
The company treated contaminated groundwater with a chemical oxidant in March. A second round of chemical injections occurred in late May.
Following those chemical injections, groundwater samples from more than 50 monitoring points show TCE concentrations decreased between 20 percent and 80 percent in four specific areas, according to the company's report released this week.
The quarterly reports are required under the cleanup plan for Whirlpool's property, which has been contaminated since at least 1989 when TCE was discovered at the site. The company sent its latest report both to the state and city of Fort Smith.
