East Palestine Surface Water Results

Surface Water Sampling and Associated Information

This surface water sampling data is generated from daily surface water monitoring from 20 sampling locations. This water sampling begins at the derailment site in East Palestine and include streams flowing to the Ohio River. This data is analyzed at a certified laboratory, testing for what’s known as volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and glycols. To ensure accuracy, the data undergoes Quality Assurance and Quality Control measures. The process is detailed; therefore, results may not be available for 4 to 6 days after the samples were collected.

We have launched this new interactive map to show you sampling results at each location.

Background samples are collected upstream to show that the detected chemicals are from the incident and not from an unrelated source upstream.

Some of the samples for 2/16 and background samples from 2/19 show elevated readings, likely a result of cross contamination either in the field or lab.

Despite declining levels of contaminants in surface water samples, prolonged exposure with the water or any human consumption of untreated surface water is strongly discouraged.
