Marsh Creek Park – Chester County Sinkhole in Pennsylvania
A massive sinkhole formed at Marsh Creek State Park wetlands in Chester County, Pennsylvania on August 11, 2020.
The hole has a width of 15 feet and a depth of 8 feet. According to state officials and Chester County commissioners, it was part of the release of drilling fluids into the wetlands last August 10.
It was also one of the sinkholes that the Chester County’s Board of Commissioners informed Pennsylvania Gov. Tom Wolf about. The holes were related to the Sunoco/Energy Transfer’s pipeline installation sites. Commissioners said sinkholes began forming in West Whiteland Township since the middle of June this year.
Department of Environment Protection Communications Officer Virginia Cain said work at the site was shut down until a restart report is approved by the department. The sinkhole was grouted temporarily with 26 cubic yards of grout. Cain said that a mitigation and remediation plan was expected to be submitted by Sunoco, indicating the removal of the grout to be replaced by native soil, as well as reseeding the area.
