The state Department of Environmental Protection says 100 gallons of concentrated herbicide that spilled from a truck has killed fish in a six-mile stretch of a central Pennsylvania stream.
DEP spokesman Dan Spadoni says a 200-gallon container of herbicide fell of the truck Monday on U.S. Route 322 in Potters Mills, Centre County and about half of it washed down a storm sewer into nearby Potter Run.
The Centre Daily Times reports the agency had confirmed by Tuesday that fish were killed as far away as Sinking Creek, about 5.8 miles away.
Spadoni says the herbicide remained toxic until it was sufficiently diluted. Because the creek is flowing higher than usual from recent heavy rains, the poison is likely diluted by now.
“However, our field staff on site have not completed their assessment to confirm this,” said Spadoni.
