MIDDLETOWN TOWNSHIP, Pa. (CBS) — A week after Sunoco agreed to address concerns that its pipeline construction was tainting well water in one Chester County community, two new problems have cropped up — this time, in part of Media, Delaware County.

A video posted to Facebook shows water overflowing a containment pit.

Its plastic barrier and hay bales, are no match for the deluge along Martins Lane and Glen Riddle Road in Middletown Township.

A spokesman for Sunoco’s Mariner East 2 pipeline calls it a “considerable amount of groundwater” pouring from the drill pad.

He notes no reports of problems with public or private water sources.

It’s the same spot that saw what the company calls “an inadvertent return of drilling mud” — a mixture of water and bentonite clay used to lubricate the underground horizontal boring equipment.

About 1,500 gallons spilled into Chester Creek. Crews worked to pump out that mud.

The state Department of Environmental Protection says there’s no health risk, no reported fish kills from the non-toxic mixture, and no expected long-term impact to the creek.
