The Department of Environmental Protection says area residents should not
fish or swim in the Sinnemhoning-Portage Creek in McKean and Cameron
Counties as biological assessments continue.

48 thousand galons of sodium hydroxide, or "lye" was poured into the creeks
when the Norfolk Southern Railroad train went off the tracks near Gardeau.

Children, and pets should be especially monitores, because concentrated
isolated pockets of the chemicals are still around.

Most of the stream ph levels are back to normal, but elevated bacteria
levels are possible because of the number of fish that were killed.
