Oilfield Contamination of Water

Missoulian: Feds: EPA fails to protect water from oilfield contamination

EPA Needs to Collect Information and Consistently Conduct Activities to Protect Underground Sources of Drinking Water

”Since the early 2000s, increased oil and gas production has resulted in an increase in wastewater that must be managed properly. The majority of wastewater from oil and gas production is injected into underground wells known as class II wells. These wells are regulated to protect drinking water sources under EPA's UIC class II well program and approved state class II programs. EPA oversees state programs, and EPA regions manage programs in states without approval.”
