"Abandoned oil field equipment is a common problem in Texas, which is home to vast numbers of old wells that were never properly sealed. . . . In recent decades, regulators have worked to plug the old wells so they do not act as a conduit for liquid pollutants to enter groundwater. But some fear that the recent surge in oil drilling, brought about by the modern practice of hydraulic fracturing, will set off worrisome encounters with the old wells. “Not every unplugged well leads to pollution, but a high percentage of wells that are left unplugged do present pollution hazards,” said Scott Anderson, an oil and gas expert based in Austin with the Environmental Defense Fund."
