Water Sampling Data

Sampling Locations

EPA collected surface water samples for analysis of including volatile organic compounds (VOCs), butyl acrylate and ethylene glycol monobutyl ether. EPA continues to support water sampling efforts collected by  Ohio EPA ,  ORSANCO , and Norfolk Southern.

U.S. EPA surface water sample locations were selected based on site observations and how water flows and from the site to nearby creeks. Samples were collected in Sulfur Run, Leslie Run, and other waterways downstream to the Ohio River.

Note: The U.S. Environmental Protection Agency is releasing preliminary water, air, and soil sampling results from East Palestine as they become available. Preliminary data should be considered raw, unprocessed information. EPA will post final data as soon as the quality has been assessed and documented.

Map filters will update lab results viewed in the list. Filters do not alter which sample locations appear in the map.
