CPANA Releases Air Monitoring Data

CPANA continues its year-long study of air quality in a Lewisville neighborhood prior to the entrance of natural gas drilling.

Although CPANA has not released any narrative yet for months 4 - 6, it is releasing the data now in the interest of maintaining openness, and will follow up with some explanation at a later time. Benzene, toluene, and xylene have all been found in quantities well below long-term effects screening levels. Samples are taken using passive diffusion tubes which soak up a sample of air over the course of a month, and when analyzed give a rough average of contamination levels. CPANA looks for benzene levels and the top nine other VOCs found in the sample tube.

Month 4: 9/19/2010 - 10/18/2010 
Month 5: 10/18/2010 - 11/16/2010
Month 6: 11/16/2010 - 12/18/2010

CPANA Board members will meet tonight to discuss possible expansion of its monitoring program to include additional locations and analytes.
