PELLA, Iowa (AP) — A federally mandated study has concluded that Pella Corp. inadvertently released two dangerous chemicals into the ground at its plant in Pella.
The Des Moines Register reports (http://dmreg.co/2eYAuaR) that the study says pentachlorophenol and dioxin have reached the groundwater. Only those two chemicals were found at higher than acceptable levels.
Pella officials say the contaminants do not threaten the city’s drinking water, which comes from the Des Moines River and the Jordan aquifer.
The study was a result of a 2010 settlement with the Environmental Protection Agency, which required the company to test for 30 different possible sources of contamination. A Pella manager, Jim Nieboer, says Pella will wait for guidance from the EPA on whether Pella must remove the chemicals from the ground.
