in the area on River Road in Gladwyne Wednesday. However, dissolved oxygen levels and pH were found to be normal, Lynda Rebarchak, in the Pennsylvania Department of Environmental Protection's Norristown office, wrote in an email.
"Montgomery County Hazmat and the local fire department reported that at most, a few gallons of diesel had entered the storm drain," wrote Rebarchak.
Because of the minor impact on the river and heavy rain overnight Tuesday, the DEP believes Wednesday's reported fish kill is unrelated, according to Rebarchak.
The DEP's investigation is continuing, she wrote.
