Air sample data available online, DEP announces

PARKERSBURG – The West Virginia Department of Environmental Protection has posted online information about hundreds of air quality samples taken in the area surrounding the fire at the Intercontinental Export Import warehouse in Parkersburg.

The information, which will be continuously updated, is available online at:

More data is being added to this report and an updated version will be posted once additional results are entered.

Sampling conducted by the WVDEP’s Homeland Security and Emergency Response team using handheld air monitors includes data on methane, oxygen, hydrogen sulfide, carbon monoxide, chlorine, and ammonia. Data collected by the federal Environmental Protection Agency (EPA) is also included in the data posted online. Additional air quality monitoring by both the WVDEP and EPA is ongoing.

The WVDEP Division of Air Quality has also announced that its air monitoring station nearby in Vienna, which is a permanent air monitoring station, measured 14.5 micrograms per cubic meter of particulates 2.5 microns and smaller over a 24-hour period on Sunday, Oct. 22. This normally would indicate a “Moderate (12.1 to 35 micrograms per cubic meter) Air Quality Index.” However, winds varied significantly over the 24-hour sampling period such that the smoke’s impact on the reading cannot be quantified. That same air monitoring station measured 8.4 micrograms per cubic meter of particulates 2.5 microns and smaller on Thursday, Oct. 19 – two days before the fire.

Also posted online is air quality monitoring results from testing conducted by the Ohio Environmental Protection Agency. Those results are available at:

These lab results indicate that all values were below short-term screening levels. The pollutants that were detected were at levels comparable to or lower than what is typically seen in urban areas.
