TOPEKA, Kan. (AP) — The state’s environmental regulatory agency is seeking public comment on a $2.3 million plan to clean up an industrial site in Topeka that is contaminated with chemicals dumped decades ago.

Investigators say the site was polluted by Reid Chemical Co., which dumped volatile organic compound that polluted the land and groundwater from the 1940s to 1960s. The cleanup is the responsibility of the site’s current user, Contech Engineering Solutions and AK Steel Corp., formerly known as Armco.

The Topeka Capital-Journal reports (http://bit.ly/1b4Of2F ) 1,529 tons of soil were removed from the site in 2008. The state’s plan calls for maintaining a three-year-old network of vapor extraction devices that draw out residual chemicals through more than 30 wells. The plan also includes injecting carbon substrate through wells to accelerate degradation of pollutants.
