‘Fracking’ wastewater floods Ohio

A semi from Pennsylvania unloads wastewater at the Devco No. 1 injection well near Cambridge, Ohio.

CAMBRIDGE — “The long line of tanker trucks waiting to unload at the Devco No. 1 injection well shows that business is good at the underground-disposal site.

When energy companies need to get rid of the millions of barrels of brine — the salty, chemical-laced wastewater that comes out of shale-gas wells — they bring most of it to places like this.

At the Devco well, the brine is injected 8,900 feet below ground, where it is expected to stay forever.

The process has been used for decades in Ohio to dispose of wastewater from fractured and traditional gas and oil wells.

These days, more than half of the brine coming to Ohio injection wells is from the shale-gas fields in Pennsylvania, where drilling has been under way for several years. The disposal industry is expected to grow as Ohio’s shale is exploited.”
