Dear Mr. Bunchuck:
On May 13, 2022,D&B Engineers and Architects(D&B) completed the SecondQuarter 2022landfill
gas monitoring event for the Town of Southold Landfill located onCox Lane, offMiddle Road (CR
48) in Cutchogue, New York. As part of this event, each of theexisting fifteen (15) landfill gas
monitoring wells (GMW-1 through 15) were screened utilizing a GEM 5000 Plus Landfill Gas
Analyzerfor the following parameters: temperature; oxygen; carbon monoxide; carbon dioxide;
hydrogen sulfide; andmethanewhich isreported in lower explosive limit (LEL) percentage. Climatic
o
conditionsat the Town of Southold Landfillon May 13, 2022were approximately 55F, overcast and
foggy, with approximately 5-10 MPH wind.
Enclosed with this letter is Figure 1, which shows theapproximate locations of each existing landfill
gas monitoring well. Also enclosed with this letter is Table 1, which lists all landfillgas monitoring
wells and their corresponding measurements as measuredduring the monitoring event. As indicated
in Table 1,methane, carbon monoxide,and hydrogen sulfidewere not detected within any of the
landfill gas monitoring wells.
The next quarterly round of landfill gas monitoring is expected to be conducted during the Third
Quarter of 2022. If you have any questions, please contact me at (516) 364-9890, Ext.3058.
