Pella Corporation has agreed to conduct an investigation and clean-up of hazardous waste releases from its facility in Pella as the result of a settlement filed Monday by the Environmental Protection Agency. Pella Corporation Spokeswoman Kathy Krafka-Harkema says the agreement to the investigation and clean-up stems from the spill of approximately two gallons of wood stain in 2001.

In 2006, the EPA identified a total of 30 different potential sources of soil and groundwater contamination during an assessment of the Pella, Iowa facility. The contaminants to be addressed by Pella are primarily solvents and petroleum products related to wood treatment activities at the facility, including the solvent pentachlorophenol which has been detected in groundwater above federal drinking water levels.

Pella Corporation has committed under EPA oversight to investigate its hazardous releases, conduct a study to identify cleanup strategies, and then implement the cleanup selected by EPA at its own expense.
