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 waste 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 measured both the LEL and percent gas levels for methane at GMW-6
in the third and fourth quarters of 2012. Although the methane level in GMW-6 remains greater
than 100% of the LEL, the percent gas level decreased slightly following installation of the
turbines, from 22.7% in the third quarter to 20.3% in the, fourth quarter of 2012. D&B will
continue to monitor the LEL and percent gas levels for methane at GMW-6.
Gas monitoring well GMW-11, located along the northern boundary of the landfill waste mass,
has intermittently exhibited elevated LEL detections for methane during previous monitoring
events, including last quarter at greater than 100% of the LEL. However, the level was
non-detect for the current fourth quarter 2012 monitoring event. Additionally, methane was not
detected at gas monitoring wells GMW-5 and GMW-13, which exhibited LEL detections for
methane of 33% and 13%, respectively, during last quarter's monitoring event. Consistent with
recent monitoring events, the remaining gas monitoring wells did not exhibit LEL detections for
methane.
Although carbon monoxide was detected in seven gas monitoring wells during the second
quarter 2012 monitoring event, it was not detected last quarter or during the current fourth
quarter 2012 monitoring event. Consistent with previous results, hydrogen sulfide was not
detected in any of the gas monitoring wells and oxygen levels were detected below typical
atmospheric levels.
The next quarterly round of monitoring is expected to be conducted during the first quarter of
2013. If you have any questions,please contact me at (516) 364-9890, Ext. 3091.
Very yours truly,
