The state Department of Environmental Protection has cited the Westmoreland Sanitary Landfill for leachate that leaked from the Rostraver facility on Wednesday and made its way into Speers Run.
The DEP is investigating. It was unable to estimate the volume of contaminated liquid that escaped, resulting in discoloration of the local stream.
DEP inspectors went to the landfill on Thursday after receiving a complaint late that morning about the leachate — liquid that picks up contamination when it comes into contact with waste material.
Leachate must continually be removed from the landfill. It normally is stored in tanks before being trucked to treatment plants, the DEP said.
