The current percent gas level in GMW-6 is 17.4%, which is higher than last quarter's 11.9% but below the 22.7% measured in the third quarter of 2012 prior to installation of the turbines. D&B will continue to monitor the LEL and percent gas levels for methane at GMW-6. Consistent with recent monitoring events, the remaining gas monitoring wells did not exhibit LEL detections for methane. With the exception of GMW-6, carbon monoxide and hydrogen sulfide were not detected in any of the gas monitoring wells, and oxygen levels were detected at and below typical atmospheric levels. Carbon monoxide was detected in GMW-6 at a trace concentration of 1 part per million(ppm). The next quarterly round of monitoring will be conducted during the third quarter of 2013.
