"D&L Energy Inc. is best known for its brine-injection well in the city that is suspected of triggering 11 Mahoning Valley earthquakes this year. But a Vindicator investigation conducted prior to the well shutdown Friday and Saturday’s magnitude-4.0 earthquake revealed the company has a history of at least 120 violations at 32 injection and extraction wells in Ohio and Pennsylvania during the past decade."

"Environmental regulators have levied violations against D&L for administrative flaws such as a failure to display a permit but also for environmental mistakes such as water and soil contamination and pollution.

Injection wells, a byproduct of fracking, have been linked to small earthquakes and often are targeted for other environmental concerns."
