The work consists 1) of semi-annual sampling and analysis of groundwater from 12 wells,
and 2) quarterly sampling and analysis of gas from 15 wells, around the landfill perimeter
(see Attachments B and C – last two pages of this document) and the preparation of reports
on the results of sampling for NYSDEC and the Town. The groundwater work will consist of
two rounds of analysis for 6 NYCRR Part 360 Baseline Parameters per year, with reports to

4 th quarters of each year).
Gas sampling will be conducted quarterly and will test for oxygen indicated in total % of

rates not exceeding 5 gallons per minute (gpm)
Utilizing calibrated water quality meters to document field parameters and the
stabilization of these parameters prior to sample collection
Documenting field sampling and field parameter stabilization with the use of the
attached well sampling form
Collection of filtered groundwater samples for metals analysis when necessary due
to sample turbidity
Collection of groundwater samples using dedicated hand bailers
Collection of required QA/QC samples including trip blanks and MS/MSDs
