Activist groups once again are calling for more information about natural gas wells plugged and abandoned near Pavillion, WY, where drinking water previously was alleged to have been contaminated by drilling. Wyoming officials concluded in late 2016 that gas drilling activity did not contaminate any water wells. In a letter sent to the Bureau of Land Management (BLM), the Pavillion Area Concerned Citizens and Powder River Basin Resource Center requested information about the issue. BLM “has received the letter...and will respond appropriately in the near future," said a spokesperson. "To date, the BLM has fulfilled its inspection and enforcement requirements” while working with field owner Encana Corp. “to plug wells in the Pavillion oil and gas field. This is a responsibility the BLM takes seriously and will continue to coordinate with the proper agencies and tribes to address concerns in the Pavillion area."
