Erin Brockovich & Susquehanna Valley, Pa. chemical pollution

Though Erin Brockovich mentions, below, that "You won't be seeing this on network news," NBC did go to the trouble of reporting that smoke from a June 5  Hanover, Pa. chemical plant explosion and  5-alarm  fire  was:

"not toxic":

Runoff contaminated the Conewago Creek, killing an estimated 20,000 - 30,000 fish so far and causing the testing of residents' water wells along the creek as it flows miles to the endangered 

Susquehanna River: 

Downstream, Lancaster, York, Columbia, Red Lion, Baltimore, and other municipalities draw drinking water from the river. Wrightsville, Pa. hurried to collect and store some before the chemical contamination reached there:

The following is from Erin Brockovich's Facebook page:

These dangerous chemicals are on their way to the Chesapeake Bay... where are the safety measures to prevent this from happening again, and again, and again, and again, and again...

York and Adams county officials have said people in the following municipalities should not swim, boat or fish in the Conewago Creek in the following municipalities:

York County, Paradise Township, Dover Township, Washington Township, Warrington Township, Conewago Township, Newberry Township, East Manchester Township, York Haven, East Berlin, Adams County, Hamilton Township, Mt. Pleasant Township, New Oxford, Oxford Township, Reading Township

Chemicals from an Adams County fertilizer business that caught fire Monday had flowed into the creek and colored the water brown and purple. Waterways Conservation Officer Dan Nietupski said more than 20,000 fish have been killed, and the number could grow as the contamination moves downstream toward the Susquehanna River.
