ALVARADO -- Does fracking cause cracking?
That's the claim in a lawsuit filed on behalf of two Johnson County families who say their homes were damaged by a series of earthquakes last summer. At least nine quakes rattled the county.
"It felt like a semi hit the side of our house," said plaintiff Jan Finn about one of the quakes.
She said it was so powerful that her husband jumped out of bed and ran outside, expecting to find a vehicle had hit their brick home.
She said within days, many cracks appeared, inside and out. She claims one was more than a half-inch wide, and the side of the house dropped.
The Finns paid $6,500 to prop up their home.
Further down Luisa Lane in Alvarado, much larger cracks pierced Ed Specht's brick home. So wide, in fact, he's stuffing them with insulation. But now a wall is bowing out, and he fears it could give way.
Specht said he can't afford to fix it, but gas drillers should.
State maps show more than a dozen wells beneath the neighborhood. Specht said he's lived in his home more than 20 years and kept the foundation watered. He said the only thing new is the wave of earthquakes.
Some experts believe waste water injection wells, not fracking, are linked to quakes in North Texas.
An attorney representing the Finns and Spechts said the waste wells are part of the fracking process. He hopes the case becomes a class action suit. The suit names four energy companies.
Sunoco and Enterprise Crude Oil tell News 8 they do not drill wells, but provide pipelines, transportation, or other services. Shell said it's studying the suit. EOG Resources is also named in the suit.
