Town of Southold DSW
December 19, 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. The current percent gas level in GMW-6 is 13.0%,
which is lower than last quarter's 13.9% and significantly lower than 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 First Quarter of
2014. If you have any questions,please contact me at(516) 364-9890, Ext. 3091.
Very yours truly,
