Box 962 Cutchogue, New York 11935-0962 RECEIVED JUN 2 8 2006 Re: Cutchogue Landfill Groundwater Well Mouitoring Program Sampling and Lab Analysis Program SOHT 06-01 Southol~ Town Clerk Dear Mr. Bunchuck: 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 baseline parameters as identified in 6 NYCRR Part 360-2.11 (d) (6). Sampling Activities The sampling program was conducted by H2M on March 16, 2006. H2M'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: IS, 3S, 4S, 5S, 6S & 8S) and one being screened in the lower depth of the aquifer (ex: ID, 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 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 H2M Labs, lnc. for the baseline suite of parameters as required by NYSDEC Part 360. Table I 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, inorganic parameters and organic parameters associated with the baseline requirements.

SURVEYORS . 1l2MGROUP James Bunchuck June 26, 2006 Page 2 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 . Volatiles Data Package . Metals Data Package . Wet Chemistry Data Package An independent validation of the baseline laboratory data was performed by Ms. Judy Harry of Data Validation Services of North Creek, New York. The validation certification from Ms. Harry will be included as part of the final report submitted to NYSDEC. Conclusions Based on 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 ammonia, phenols, and bromide; inorganic parameters to include magnesium, manganese, sodium, and thallium; organic parameters to include 1,2-dichloropropane. A review of the laboratory data from the quarterly monitoring program since April 2005 does not yield any trend in the analysis. A review of the laboratory data for the trend analysis will be included in the next quarterly round of sampling. Upon your 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 (xI6l0).
