Officials Say Detergent Spill in Allegheny 2nd in a Week

State environmental officials say the same kind of industrial detergent that spilled into the Monongahela River in Fayette County a few days ago has now gone into the Allegheny River from a Harmar treatment plant.

The spill of ethoxylated alcohol from the Allegheny Valley Joint Sewage Authority treatment plant in Harmar occurred Thursday, said plant manager Rich Chiavetta. The state Department of Environmental Protection says it was reported Friday. Mr. Chiavetta said about 10,000 gallons was released. The Pittsburgh Water and Sewer Authority said the drinking water supply was not affected.

On Wednesday, the same chemical leaked from a containment pit in Newell into the Monongahela River. A number of fish were killed due to the spill.

The chemical is found in some household detergents and can be harmful in concentrated form, but officials say it is toxic to aquatic organisms.
