Re: TOWN OF SOUTHOLD Landfill, Quarterly Sampling and Laboratory Analysis Program
H2M Project No. SOHT0801
MR. CAVA,
On behalf of the TOWN OF SOUTHOLD,HOLZMACHER, MCLENDON,AND MURRELL,P.C.
(H2M)completed a quarterly sampling and laboratory analysis program for the groundwater monitoring
wells located at the TOWN OF SOUTHOLD Landfill on MIDDLE RD, SOUTHOLD,NY. These well
locations are shown on the attached Monitoring Well Location Map. We provide herein the results of
our findings for the routine suite of parameters as identified in 6NYCRR Part 360.
Sampling Activities
The sampling program was conducted by H2M on 11/3/08 and 11/5/08. H2M's sampling protocol called
for monitoring/sampling six groundwater monitoring well clusters distributed around the perimeter of the
landfill; please refer to the enclosed well location map for the approximate location of these well
clusters. Each well cluster is comprised of two groundwater monitoring wells, one being screened in the
upper depth of the aquifer(i.e., I S, 3S, 4S, 5S, 6S, 8S)and one being screened in the lower depth of the
aquifer(i.e., 1 D, 3D, 4D, 5D, 6D, 8D). Each water sample from a well was taken by purging three static
well volumes with a submersible pump,then discharged ten feet from the well, and collected with a
disposable bailer. Cross contamination concerns were eliminated by using disposable bailers in
conjunction with cleaning the submersible pump with laboratory grade biodegradable detergent and
disposable nitrile gloves. The sampling program was conducted based on the specifications included in
the Southold Landfill Groundwater Quality Assurance/Quality Control Plan.
Analytical Results
Each sample was analyzed by H2M LABS, INC. for the routine suite of parameters as identified in
6NYCRR Part 360. Table 1, enclosed with this letter, summarizes the groundwater well construction
data and includes surface elevation, depth to water and depth to bottom of borehole, and groundwater
well installation dates. Table 1 also summarizes the field parameters collected during the sampling
program along with the laboratory analysis for leachate indicators,and inorganic parameters.
The laboratory test results were compared to the NEW YORK STATE DEPT OF ENVIRONMENTAL
CONSERVATION (NYSDEC) standards as identified in the Division of Water Technical and

dated June 1998. A CD-ROM containing, in PDF, the set of the H2M LABS, INC. data packages
entitled Sample Data Summary Package, Metals Data Package, and Wet Chemistry Data Package are
enclosed for your record.
Conclusions
A review of the lab test results, as compared to the NYSDEC standards, indicate that several
groundwater wells in-the sampling program have analytes in exceedence to said standards. Table 1
indicates these exceedances(see note 1)for leachate indicators including ammonia,chloride, and
inorganic parameters including iron, magnesium, manganese,and sodium.
