Re: Town of Southold Landfill
Gas Monitoring Well Monitoring Program, Q1 and Q2 of 2009
1-12M Project No. SOHT0901
Dear Mr. Bunchuck:
As detailed in our letter proposal dated November 17, 2006, our office conducted landfill gas
monitoring for the existing fifteen gas monitoring wells (i.e., located in the southwest, south,
and southeast perimeter of the landfill) at the Town of Southold Landfill located on Middle
Road (CR 48) in Cutchogue, New York. Said monitoring program was conducted on March
26, 2009, and on June 5, 2009, and said wells were monitored on both days with a RAE
Systems VRAE 7800 Gas Surveyor. Weather conditions on March 26, 2009, were observed to
be sunny and approximately 45 deg. F. and partly cloudy, and weather conditions on June 5,
2009, were observed to be about 56 deg. F. with light rain.
Enclosed with this letter are Figure 1 and Table 1. Figure 1 shows the approximate locations
of these gas monitoring wells, and Table 1 lists these gas monitoring wells and their
corresponding levels of carbon monoxide, oxygen and lower explosive limit (LEL) for
methane as measured on March 26, 2009 and on June 5, 2009.
If any questions should arise, please contact the undersigned at (631) 756-8000.
Very truly yours,
HOLZMACHER, McLENDON & MURRELL, P.C.
