Wichita — Cindy Hoedel and Scott Yeargain, who live in or near the Kansas Flint Hills, began looking into oil and gas operations near their homes as early as 2016.

The two, separately, worried about earthquakes and water quality issues that new wastewater injection wells would create.

Hoedel documented a few dozen instances where injection well permit applications didn’t follow Kansas Corporation Commission guidelines. That led to a KCC report identifying more than 1,000 similar cases.
