I OF SOU
OF SOLID
In accordance with our engineering services contract dated April 4, 2005, our- office completed a quarterly
sampling program and -laboratory analytical services for the groundwater monitoring well locations at the
Cutchogue Landfill located on Middle Road. We provide herein the results of our findings for the routine
parameters as identified in 6 NYCRR Part 360-2.11 (d) (6).
Sampling Activities
The sampling program was conducted by H2M on September 12, 2006. 112M's sampling protocols called
for locating -six (6) monitoring well clusters distributed around the perimeter of the landfill. See the
attached site plan for- the approximate location of the well clusters. Each well cluster is comprised of two
(2) monitoring wells, one being screened in the upper depth of the aquifer (ex: 1S, 3S, 4S, 5S, 6S & 8S)
and one being screened in .the lower depth of the aquifer (ex: 1D, 3D, 4D, 5D, 6D, & 8D). Each water
sample from a well was taken by purging three (3) static well volumes with a submersible pump,
discharged ten (10) feet from the well and collected with a disposable bailer. Cross contamination
concerns were eliminated by using these disposable bailers in conjunction with cleaning the submersible
f
pump with laboratory grade biodegradable detergent, (i.e..Alconox) and with 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 1-12M Labs, Inc. for the routine suite of parameters as required by NYSDEC
Part 360. Table 1 summarizes the groundwater well construction data to include surface elevation, top of
casing elevation, depth to water, depth to bottom of borehole and groundwater well installation date. All
groundwater wells are constructed with 2" diameter screens and risers and with a 6" diameter protective
casing. Table 2 summarizes the field parameters collected during the sampling program along with the
laboratory analysis for leachate indicators and inorganic parameters associated with the routine
requirements.

The laboratory test results were compared to the NYSDEC standards as identified in the Division of
Water Technical and Operational Guidance Series (TOGS) (1.1.1) — Ambient Water Quality Standards
and Guidance Values dated June 1998. A set of the H2M Labs, Inc. data packages are enclosed for your
records as follows:
• Sample Data Summary Package
• Metals Data Package
• Wet Chemistry Data Package
Conclusions
Basedon a review of the groundwater well laboratory data and a comparison to NYSDEC groundwater
standards indicate that several wells in the sampling program exceed the State groundwater standards.
Table 3 has been provided which summarizes the exceedances for leachate indicators to include phenols
and bromide and inorganic parameters to include iron, manganese and sodium.
A review of the laboratory data from the quarterly monitoring program since April 2005 shows continued
exceedances in various wells for phenols and sodium.
Upon review and approval of this draft report, our office will submit to NYSDEC the final report as
required by the Landfill Closure Plan. If any questions arise on the sampling program or laboratory
results please contact our office at 756-8000 (x1610).
Very truly yours,
