The earthquakes that have shaken Dallas and Irving, Texas the last several months have people looking into whether oil and gas activity in the area plays a role. Some of those people work at the Environmental Protection Agency. But EPA researchers say they’re not getting the data they’ve requested from Texas state oil and gas regulators to investigate the link.
Philip Dellinger is head of the EPA’s Underground Injection Control Section in Dallas. At a conference of the Groundwater Protection Council on Tuesday, he showed early results from a study his team conducted on earthquakes around Irving.
The group looked at the use of waste water disposal wells closest to Irving earthquakes. Dellinger does not necessarily believe the recent quakes are related to disposal wells, where waste water from oil and gas drilling is pumped underground. But these types of wells have caused other earthquakes, so his team wanted to see what wells were close to the Irving events.
