Monongahela River - Report of sheen on river

MUB is aware that “a large sheen” of what appears to be diesel fuel has been reported on the Monongahela River. Our water quality monitoring system did not trigger an alert and we have verified that our intake has not been affected. Based on this information, we conclude that the oil sheen originated downstream of our intake. We understand that DEP is investigating. We will continue monitoring the situation and will notify the public if any changes occur that relate to MUB.
