DVIRKA AND BARTILUCCI CONSULTING ENGINEERS James Bunchuck Page Two Solid Waste Coordinator Town of Southold DSW March 15, 2013 In an attempt to mitigate the elevated methane levels detected in GMW-6, the Town installed wind-driven turbine exhaust fans on the three landfill gas vents located nearest to GMW-6 and within the landfill mass. 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. Although the methane level at GMW-6 remains greater than 100% of the LEL, the percent gas level has shown a decreasing trend.following installation of the turbines, from 22.7% and 20.3% in the third.and fourth quarters of 201.2, respectively; to 11.9% for the current first quarter 2013 monitoring event. D&B will continue to monitor the LEL and percent gas levels for methane at GMW-6. Consistent with the previous fourth quarter 2012 monitoring event, the remaining gas monitoring wells did not exhibit LEL detections for methane. In addition, 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 will,be conducted during the second quarter of 2013. If you have any questions, please contact me at(516) 364-9890, Ext. 3091.
