Landfill Gas Monitoring Program, Fourth Quarter 2021
D&B No. 5535
Dear Mr. Bunchuck:
On December 7, 2021 D&B Engineers and Architects(D&B) completed the Fourth Quarter 2021
landfill gas monitoring event for the Town of Southold Landfill located on Cox Lane, off Middle Road
(CR 48) in Cutchogue, New York. As part of this event, each of the existing fifteen (15) landfill gas
monitoring wells (GMW-1 through 15) were screened utilizing a GEM 5000 Plus Landfill Gas
Analyzer for the following parameters: temperature; oxygen; carbon monoxide; carbon dioxide;
hydrogen sulfide; and methane which is reported in lower explosive limit (LEL) percentage. Climatic
o
conditions at the Town of Southold Landfill on December 7, 2021 were approximately 43F, mostly
cloudy, with approximately 5-10 MPH wind.
Enclosed with this letter is Figure 1, which shows the approximate locations of each existing landfill
gas monitoring well. Also enclosed with this letter is Table 1, which lists all landfill gas monitoring
wells and their corresponding measurements as measured during the monitoring event. As indicated
in Table 1, methane, carbon monoxide, and hydrogen sulfide were 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 First Quarter
of 2022. If you have any questions, please contact me at (516) 364-9890, Ext.3058.
Very truly yours,
Keith Robins, P.G.
