Norfolk Southern is making progress on the next phase of its mandated cleanup of East Palestine鈥檚 creeks, according to Ohio environmental officials, following the company鈥檚 train derailment nearly a year ago.
Weeks after the derailment, the U.S. Environmental Protection Agency required Norfolk Southern to from both land and water, including Sulphur Run and Leslie Run. In October, the EPA ordered additional creek investigation and cleanup in the village鈥檚 waterways.
鈥淲hat we're experiencing now is the contamination that is trapped under a rock. It's in the in the sediment, under the water,鈥� Ohio EPA Director Anne Vogel said. 鈥淪o, we continue to test the water quality itself, we look for contamination in sediment, and we count the fish and the bugs to see how aquatic life is doing.鈥�
The cleanup is entering the last phase called site characterization, Vogel said, meant to ensure contaminated sediment in the waterways doesn鈥檛 get missed.
鈥淲e go back over everything we've dug and take additional samples to make sure that there's no contamination found,鈥� she said. 鈥淭hat work will take into the spring, but again, that's just going back and making sure we got it all.鈥�
Contaminated soil was removed in October, and creek cleanup efforts will continue through the spring, Vogel said, but the amount of contamination in the water poses no danger to residents.
鈥淲e are talking about very, minor amounts of contamination remaining, and so it's not that it would be a danger to the public,鈥� she said. 鈥淚f there were significant levels of contamination that we were still finding downriver, we would obviously make sure that people were not exposed to that in town.鈥�
Cleanup crews are using a process called aeration to stir up contaminated sediment in the creek, exposing it to oxygen and allowing the contamination to dissipate in the air. For culverts where the streams run under buildings in East Palestine, technology like a robotic 鈥渄og鈥� called Muck are use to take samples and remove contamination.
Testing of groundwater in East Palestine will be ongoing for several years, to ensure contamination from the creeks doesn鈥檛 pose risk to the village鈥檚 drinking water.
Ohio EPA will also continue tracking aquatic life in the creeks, that Vogel said is being restored as contamination is removed from the water.
鈥淲e will be out again next summer in the field season to count the fish and the bugs. It's a great thing that we get to do at the Ohio EPA,鈥� she said. 鈥淲e have data from before the derailment, so we will have data from after the derailment, and we will be able to know exactly if aquatic life was affected.鈥�
