Town of Southold DSW
August 27,2013
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 13.9%,which is lower than last quarter's 17.4% as well as 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 will be conducted during the Fourth Quarter of 2013. If you have
any questions,please contact me at(516)364-9890,Ext. 3091.
Very truly yours,
