GMW-11, located along the northern boundary of the landfill waste mass, also exhibited an LEL
detection for methane greater than 100%. GMW-11 has intermittently exhibited LEL detections for
methane during previous monitoring events, the last time at 29% in the first quarter of 2012. There
were lower LEL detections for methane at gas monitoring wells GMW-5 at 33% and GMW-13 at
13%, located along the eastern and southern boundaries of the landfill waste mass, respectively.
These wells have occasionally exhibited similar methane levels during previous monitoring events,
such as in 2008.
Although carbon monoxide was detected in seven gas monitoring wells during the previous Second
Quarter 2012 monitoring event, it was not detected during the current 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 Fourth Quarter of
20.12. If you have:_any questions,please contact me at(516) 364-9890, Ext. 3091.
Very truly yours,
