Some Pennsylvania cows have had to be quarantined after coming into contact with toxic wastewater from a hydraulic fracturing operation. The incident is just the latest to raise concerns about the safety of hydraulic gas drilling in the state.
According to Reuters, the 28 cows, which were quarantined May 1, had access to a pool of toxic water for at least three days. The pool formed as a result of a leak in a wastewater holding pond on a farm in Tioga County. Eastern Resources Inc. was drilling for natural gas on the property.
