The turbines were installed in September 2012, following the third quarter 2012 landfill gas monitoring event. In order to determine the effectiveness of this remedial measure, D&B has been measuring both the LEL and percent gas levels for methane at GMW-6 since the third quarter of 2012. The current percent gas level in GMW-6 is 29.0%. Although the recent trend in the percent gas level has been generally decreasing, the current level of 29.0% is higher than the 13.0% measured last quarter and the 22.7% measured in the third quarter of 2012 prior to the 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. 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. The next quarterly round of monitoring is expected to be conducted during the Second Quarter of 2014. If you have any questions, please contact me at(516) 364-9890, Ext. 3091.
