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 well pad.

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 well pad and the other would be in the path of wind traveling across the well pad (downwind).
