Gas Monitoring Well Program
H2M Project No. SOHT 07-01 TOWN OF SOUTHOLD
DEPT OF SOLID WASTE
Dear Mr.Bunchuck:
As detailed in'our letter proposal dated November 17, 2006, our office conducted a round of monitoring
for the gas monitoring well monitoring program for the Town of Southold Sanitary Landfill located on
Middle Road (CR 48) in Cutchogue,NY. The monitoring program was conducted on December 6, 2007
for the fifteen (15) gas monitoring wells at the southwest, south and southeast perimeter of the landfill.
Figure 1, previously prepared by Dvirka & Bartilucci, is provided which indicates the location of the gas
monitoring wells at the landfill. The field program included the measurement of oxygen and combustible
gases for each of the wells as required by New York State Department of Environmental Conservation.
H2M utilized a RAE Systems Q-RAE Multi-Gas monitor for oxygen and combustible gas (percent of
lower explosive limit [LEL]) from the sampling ports of the gas monitoring wells. The following table
summarizes the findings of the December 6,2007 gas monitoring well program:
Percent
Gas Probe LEL Percent Oxygen
GMW-1 0 19.8
GMW-2 0 20.0
GMW-3 0 20.2
GMW-4 0 19.8
GMW-5 0 19.6
GMW-6 100+ 4.2
GMW-7 0 17.8
GMW-8 0 16.9
GMW-9 0 19.8
GMW-10 0 11.4
GMW-11 100+ 5.4
GMW-12 0 18.2
GMW-13 1 15.5
GMW-14 1 18.9
GMW-15 0 20.0

The results indicate that there is currently a threat of combustible gas migrating beyond the boundary of
the landfill in the vicinity of GMW-6 and GMW-11 located in the southeast and east portions of the
landfill. The next quarterly round of monitoring is expected to be conducted during March of 2008.
If any questions arise concerning the gas monitoring well program, please contact the undersigned at
(631)756-8000 Ext. 1484.
Very truly yours,
HOLZMAC R,MCLENDON& MURRELL,P.C.
