Penneco has proposed converting Sedat 4A from a conventional gas well into an “injection well,” which would enable the company to pump millions of gallons of produced water at high pressure down the well’s existing metal tubes that are encased in layers of cement and bore thousands of feet deep into the ground. Produced water is highly toxic and can contain benzene, arsenic and radium 226 and 228, both radioactive isotopes, as well as other toxic chemicals from its time underground.
