Air Quality Monitoring

Upwind and downwind air quality monitoring equipment measuring PM2.5 (particulate matter) and VOCs known as BTEX was installed within 500’ of the station.

The prevailing wind direction for this region is from the southwest. CNX positioned the PM2.5 monitors such that one would be subject to winds from upwind of the station and the others would be in the path of wind traveling across the station (downwind).

Due to the lack of a West Virginia Department of Environmental Protection (DEP) ambient air monitoring station within close proximity to the Shirley Station site, no regional background data are available for direct comparison to the site-specific results. This limitation may affect the ability to contextualize site-specific measurements against regional baseline conditions. Users are encouraged to consider this when reviewing the monitoring data presented.
