This report is intended to determine the concentration of pesticides and metals in site soils, since these substances were widely used for weed and pest control in Long Island agricultural practice. The subject properly consists of a 46.16 acre parcel of fallow farm field and wooded land located in the Hamlet of Cutchogue, Town of Southold, County of Suffolk, New York. The subject property is located at the northwest corner of Griffing Street and School House Lane, I approximately 1,079 feet north of Main Road, Cutchogue. The parcel is more specifically identified as SCTM No. 1000-102-1-33.3. This document will be used to assist in evaluating the environmental and/or public health implications regarding the current concentrations of agricultural chemicals in on-site soils. � The sampling program was designed and completed by N&P. Laboratory analytical data was i prepared by Long Island Analytical Laboratories, Inc. The protocol used to direct this investigation was based upon the guidance offered by the Suffolk County Department of Health Services (SCDHS) in a report entitled Procedures for Municipalities to Evaluate the Need for ; Soil Sampling and Soil Management at Subdivisions or Other Construction Projects with � i Potentially Contaminated Soils._This SCDHS document is based on i_nitial guidance from the ' New York State Department of Health Bureau of To�c Substance Assessment. The following '' sections detail the subject property and surrounding area characteristics, sampling program, i protocol and quality assurance, lab analysis and results. A total of eighteen (18) soil samples were collected from nine (9) sampling locations situated � throughout the property. Specifically, soil samples were collected from depths of 0-3 and 3-6 inches at each of the nine (9) sampling locations. Due to the past use of a majority of the i property for agricultural purposes, the samples collected from five (5) locations were analyzed �� for the presence of pesticides and metals and the samples collected from the remaining four (4) I locations were analyzed for arsenic which is a common constituent associated with pesticides. Initially, only the samples from the 0-3 inch intervals were analyzed. If any detected compounds within each individual sample were found to exceed their respective regulatory guidance values ; only then was the associated 3-6 inch interval sample analyzed. Review of the analytical results revealed the presence of elevated levels of arsenic and mercury which exceeded there respective regulatory agency guidance values across the subject properly. As a result the 3-6 inch interval � samples were analyzed for the presence of arsenic and mercury only and the analytical results revealed elevated concentrations of both constituents. In order to identify the depth to which � arsenic and mercury were present, soil samples were collected from the three (3) of the previous sampling locations which exhibited the highest concentrations. The following sections of this report outline the sampling measures taken and provides a map illustrating the location of the ' samples collected. Appropriate recommendations are provided in Section 5.0. j I � - �he Heritaget3a-Cutchogue Pesticide Report 2.0 SAMPLING AND ANALYSIS PROGRAM(SAP) 2.1 SAMPLE COLLECTION A total of eighteen (18) soil samples were collected from nine (9) locations situated throughout � the subject property on October 24, 2007. The soil samples were collected froin depths of 0-3 and 3-6 inches below grade. Samples collected from five (5) of the locations were analyzed for the presence of pesticides and metals and the samples collected from the remaining four (4) locations were analyzed for arsenic which is a common constituent associated with pesticide use. The depths of the soil samples were selected to provide a profile of the soil located on the subject property. Initially, only the samples from the 0-3 inch intervals were analyzed. If any detected compounds within each individual sample were found to exceed their respective regulatoiy guidance values only then was the associated 3-6 inch interval sample tested. Results from both sample intervals revealed the presence of elevated concentrations of two (2) metals and as a result it was concluded that further sampling was necessary to identify the depth to which these i inorganic compounds were present at the subject property. Additional sampling was conducted at the three (3) previous sampling locations which exhibited the highest concentrations and � samples were collected at depths of 9-12 inches, 15-18 inches and 21-24 inches below ground surface on November 10, 2007. The sampling scheme employed was consistent with guidance j available from SCDHS as referenced herein. A stainless steel hand auger decontamivated between uses (see Section 4.0), was used t� extract � all of tU�e soil samples from the subject pr�perty. Figure 1 pr.ovides a map that identifies the j � various locations from which the soil�samples were collected. The topography of the subject property is relatively flat. 2.2 SAMPLING PROGRAM RATIONALE i ; Soil samples were collected in accordance with the recommendations of the SCDHS and N'YSDOH,noted as follows: ., � • samples were collected at depths of 0-3,3-6,9-12, 15-18 and 21-24 inches. � • samples were directed toward those areas likely to_have accumulated the highest contaminant ! levels. • samples were analyzed for the presence of pesticides and metals. I Laboratory analysis results are discussed in Section 3.0. Since the proposed properly will be � used for a residential subdivision, the concentration of pesticides and metals is an important � issue. Tn accardance with SCDHS and NYSDOH recommendations, the sampling and analysis program � was intended to detennine: � � if site activities had caused degradation of soil quality on site; � • if a soil management plan (SMP) is appropriate given the concentration of contaminants and the intended use of the site. The following section provides the laboratory analysis for the site samples, including test I methods and analytical results.

Selection of the analytical test methods for the soil samples was based on the NYSDOH and SCDHS recommended soil sampling parameters for agricultural soils on Long Island. Analysis of the soil samples consisted of pesticides and SCDHS metals for five (5) of the 0-3 inch samples and only arsenic for four (4) of the 0-3 inch samples. Review of the analytical results revealed that the 3-6 inch satnples from all of the locations required testing. Specifically, all of the 3-6 inch samples were analyzed for arsenic and in addition, three (3) of the 3-6 inch samples were analyzed for mercury as well. Review of the results continued to reveal elevated concenirations of inercury and arsenic. In order to identify the depth to which arsenic and mercury were present, soil samples were collected from the three (3) of the previous sampling locations which exhibited the highest concentrations. A sumivary of the parameters analyzed for each sample is provided in Table 1. � � � I 3.2 ANALYTICAL RESL]LTS ( Review of the analytical results for the 0-3 inch interval samples revealed that the five (5) � samples selected to be analyzed for pesticides all contained elevated levels of pesticide _ comp.ounds.

All of the � samples were found to contain elevated levels of several metals. Of these metals detected, only � arsenic was found to exceed its corresponding SCDHS guidance value of 4 mg/kg in all of the I samples analyzed. In addition, mercury was found to exceed its—carresponding NYSDEC TAGM 4046 recommended soil cleanup objective of 0.1 mg/kg in three (3) of the nine (9) samples analyzed but was detected below its corresponding USEPA SSL of 610 mg/kg. ! I With regard to the four(4) 0-3 inch samples analyzed only for arsenic, all were found to contain ; elevated levels which exceeded the SCDHS guidance value. � Based on the 0-3 inch sample results, the 3-6 interval sainples from each of the locations were analyzed as per the parameters summarized in Table 1. Review of the 3-6 inch interval sample results revealed that arsenic exceeded the SCDHS guidance value in all of the samples analyzed. � With regard to mercury, it was found to be detected above its NYSDEC TAGM 4046 ; recommended soil cleanup objective in three (3) of the 3-6 inch samples analyzed and was also found to be below its USEPA SSL in each of these samples as well. � I Page 4 of 11 � The Heritage @ Cutchogue Pesticide Report Table 1 ' � Individual Sample Param�ters � ��:� .�!. -� �,��� a���,c ���ara� ,� - 0-3 Pesticides&SCDH Metals 3-6 Arsenic ' 0-3 Pesticides & SCDH Metals 3-6 Arsenic&Mercury 9-12 Arsenic&Mercury 15-18 Arsenic&Mercury ! 21-24 Arsenic&Mercury 0-3 Ars�nic i 3-6 Arsenic ; 0-3 Arsenic � 3-6 Arsenic � 0-3 Pesticides& SCDH Metals 3-6 Arsenic&Mercury ' � 9-12 Arsenic&Mercury � 15-18 Arsenic&Mercury 21-24 Arsenic&Mercury ; 0-3 Pesticides& SCDH Metals � 3-6 Arsenic 0-3 Arsenic 3-6 Arsenic ' 0-3 Pesticides& SCDH Metals � � 3-6 Arsenic &Merc i 0-3 Arsenic I 3-6 Arsenic i 9-12 Arsenic&Mercury 15-].8 Arsenic&Mercury 21-24 Arsenic&Mercu � Based on the 3-6 inch sample results samples were collected from the 9-12, 15-18 and 21-24 ' inch intervals from the locations of PS-2, PS-5 and PS-9 to further evaluate the vertical extent of i arsenic and mercury contamination.

All samples were collected by or under the auspices of USEPA trained personnel having completed the course Sampling of Hazardous Materials, offered by the Office of Emergency and Remedial Response. Separate QA/QC measures were implemented for each of the instruments used in the Sampling ', and Analysis Program. Sampling instruments included a stai_nless steel hand auger and sample ! vessels. Prior to arrival on the subject property and between sample locations, the hand auger was decontaminated by washing with a detergent (alcono�liquinox) and potab�e water solution with distilled water rinse. All sample vessels were "level A" certified decontaininated containers. Samples were placed into vessels consistent with the analytical parameters. After acquisition, samples were preserved in the field. All containerized samples were refrigerated to 4° C during transport. A sample represents physical evidence, therefore, an essential part of liability reduction is the proper conirol of gathered evidence. To establish proper control, the following sample � identification and chain-of-custody procedures were followed. Sample Identification Sample identification was executed by use of a sample tag, logbook and manifest. Documentation provides the following:. 1. Project Code 2. Sample Laboratory Number � 3.

Laboratorv Custodv Procedures A designated sample custodian accepted custody of the shipped samples and verified that the information on the sample tags matched that on the Chain-of-G�istody records. Pertinent information as to shipment, pick-up, courier, etc, was entered in the "remarks" section. The custodian then entered the sample tag data into a bound logbook which was arranged by project code and station number. ' The laboratory custodian used the sample tag number or assigned an unique laboratory number to each sample tag and assured that all samples were transferred to the proper analyst or stored in the appropriate source area. I The custodian distributed samples to the appropriate analysts. Laboratory personnel were . j responsible for the care and custody of samples from the time they were received until the sample i was exhausted or returned to the custodian. ; All identifying data sheets and laboratory records were retained as part of the permanent site �' record. Samples received by the laboratory were retained until after analysis and quality i assur.ance checks were completed. - i � I ( I i ; ( ; I I � � , � � , I i � � Page 7 of 11 , I The Heritage @ Cutchogue ' Pesticide Report ' l I 5.0 SLTIVIMARY AND CONCLUSION This investigation was completed in order to determine if certain pesticide related compounds were present in the soils of the subject property. A sampling and analysis program (SAP) was designed to deteimine the concentrations of pesticides and metals in the soil in accorda_nce with guidance offered by SCDHS and NYSDOH. The SAP consisted of collection of discrete soil samples at depths of 0-3 and 3-6 inches on the property. Laboratory analysis of the soil samples was performed using analytical test methods consistent with expected parameters and SCDHS/NYSDOH guidance. The following presents an evaluation of the results of this investigation. 1. A total of eighteen (18) soil samples from nine (9) sampling locations were collected from low points and strategic locations throughout the properry. Specifically, samples were collected from 0-3 and 3-6 inch intervals at nine(9) individual sampling locations. Soil samples were analyzed for compounds related to former pesticide application due to the past and present use of the I property for agricultural purposes. I 2. Review of the analytical results for the 0-3 inch interval samples revealed that the five (5) samples selected to be analyzed for pesticides all contained elevated levels of pesticide compounds. However, none of the pesticide compounds detected were found to exceed there respective United States Environmental Protection Agency (LJSEPA) Soil Screening Levels (SSLs) or New York State Department of Environmental Protection (NYSDEC) Technical I Administrative Guidance Memorandum (TAGM) 4046 recommended soil cleanup objectives. In i � addition, each of these five(5) samples were also analyzed for the presence of inetals. All of the I samples were found to contain elevated levels of several metals. Of these metals detected, only � arsenic was found to exceed its corresponding SCDHS guidance value of 4 mg/kg in all of the samples analyzed. In addition,mercury was found to exceed its corresponding NYSDEC TAGM 4046 recommended soil cleanup objective of 0.1 mg/kg in three (3) of the nine (9) samples � analyzed but was detected below its corresponding USEPA SSL of 610 mg/kg. With regard to � the four(4) 0-3 inch samples analyzed only for arsenic, all were found to contain elevated levels which exceeded the SCDHS guidance value. Based on the 0-3 inch sample results, all three (3) the 3-6 interval samples were analyzed for arsenic and three(3) of the samples were analyzed for � mercury. Review of the 3-6 inch interval sample results revealed that arsenic exceeded the ' SCDHS guidance value. With regard to mercury,it was also detected above its NYSDEC TAGM ' 4046 recommended soil cleanup objective in all three (3) of the 3-6 inch samples analyzed but was found to be below its USEPA SSL in each of these samples as well. � 3. Based on the 3-6 inch sample results samples were collected from the 9-12, 15-18 and 21-24 inch ' intervals from the locations of PS-2; PS-5 and PS-9 to further evaluate the vertical extent of � arsenic and mercury contamination. Review of the analytical results detected the presence of mercury in seven(7) of the nine(9) samples collected but none were found to exceed the USEPA I SSL or NYSDEC TAGM 4046 recommended soil cleanup objective for mercury. Arsenic was . detected in six (6) of the nine (9) samples collected and one (1) exceeded the SCDHS guidance � . j value. I i i i i , I i ' Page 8 of 11 ' The Heritage @ Cutchogue PeshcideReport- In sumtnary, representative soils on the subject property were sampled and analyzed for the ! presence of pesticides and metals. Based on the laboratory results, elevated concentrations of ', arsenic and mercury were identified. As a result, it is recommended that a soil management plan be prepared to mitigate potential exposure to arsenic and mercury. i i i � � � i I . i i i ( j � � i i � li I � i Date of Completion Gary Becker,P.E.

(i.e.,commercialrndustrial)exposure scenarios. Exhibit A-1 presents updated generic SSLs for the resideneia!-exposure scenario. The generic SSLs for three of#he pathways in this exhibit — � . inhalation of volatiles in outdoor air, inha(ation of fugitive dust,and migration to graund water— , were calc�lated using the same equations and de#'ault values for e�posure assumptions found in the ' 1995 SSG(and reproduced in Appendix B of this document). Howev�r,#hey incorporate updated '' � values for dispersion factors,for taxicity,and£or other chemical-specific parameters presanted in . Appendix C. The exhibifi also presents new SSLs for concurrent exposures via soil ingesYion ar�d dermal absorption that are based, in part, on a new quantitative approach for evaluating �ermal : absorption. SSLs for combined direct ingestion and dermal absorption exposures to contaminants , were calculated according to the method described in Sectian 3.2.I of this document. The generic residential SSLs in E�hibit A-1 supersede those published in the 1995 SSG. : Exhibits A-2 ar�d A-3 present commerciaUindustria(SSLs for the outdoor tvorlcer an� indoor I . �vorker receptors,respectivefy. These SSLs have been calculated using the equations anc[the default values for exposure assumptions and other input parameters presented in Section 4.2,3 of this � � guidance document. AII aeneric SSLs presented in this appendia, both residential and ' i commercial/industrial, are rounded to two significant figures,with the exception of values less than • 10 mg/lcg, which are raunded to one significant figure. _ .. ; � As noted above, #he values in this.Appendix are based on chemica!-speoific physica� and � . toxicological parameters presented in Ap�endix C. The values in Appendix C represent the most recent values availabie and are currene as �f the date of publication of this guidance. However, ! physical/chemicaI and toxicobgical data are subject to revision and should therefore be epnfrmed ( before referencing screening levels in the following tables. Tricltloroethy(ene,in particular, is based ��i on �a draft risk assessment, and because the document is still undergoing reviev��, the health � benchmark values shouId be cpnsidered provisional. � EPA does not present generic SSLs for the construction e�posure scenario because the i c�mplexity �and variability of exposure conditions for construction activities precludes the � . development of such values. For information on developing SSLs for e:cposures during construction ; activities; users shoutd refer to Chapter 5 or Appendix E af the guidance document. I� . The generic residential and non-residential SSLs are nat necessarily protective of all l:nown � human e�posure pathways or ecological threats. Before ap lyin SSLs it is theref�re necessa to � A g � ry , ' compare the conceptuaI site model (developed in Step l of the svil screening process) with th� � assumptions underlying the generic SSLs ta ensure that site conditions and exposure patttways are consistent with these assum,ptions (See Exhibit A-4.) If tliis comparison indicates that the site is • ' more complex than the generie SSL scenario, or that there are signiftcant exposure pathways not � accounted for by the SSL scenario, then generie SSLs aione are not suff cient#o evaIuate the site, { ; and additional, more detailed site-specific investigation is necessary. • A-t I . ; I � ' In each exhibit, the first column presents SSLs based on the combined soii ingestion and � � dermal absorption exposure pathway. When data oi� dermaI absorption from soil are unavailable, these SSLs are based on ingestion exposures only. SSLs far this pathway may be updated in the : future as derma[absorption data become avaiEable fQr other contaminants. � The second column in Exhibits A-t and A-2 presents SSLs for tiie outdoor inl�afation of � volati[es pathway. AlthouDh residential receptors and indoor workers are potentially exposed to _ volatiles in indoor air as well, EPA has not calculated generic SSLs far migration af volatiles into indoar air because it is vez��difficult to identify suitable standardized defauit vaiues for input�such � as dimensions of commerciai buildings and the distance between contamination and a buiiding's . foundation. EPA provides spreadsheet models tha#can be used to ca[cuiate SSLs for this pathway using the simple site-specific or detailed site-specific approaches.� The third coIutnn in Exhibit A-i � and A-Z(ists SSLs for the inhalation of fugitive dusts pathway. Beeause inhalation of fugitive dust . is typicaliy not a,concem for organic compounds, SSLs for this pathwaY ara presented anly for inorganic compounds, which�are.listed at the end ofeach exhibit. Converse(y, with the exception of inercury,no SSLs for the inhaIation ofvolatiles pathway ara provided for inorganic compounds � � becavse fihese chemicals exhibit extremeiy lo4v volatility. - The user shou(d note that several of the generic SSLs for the inhalation of voiatites patl7way , are dekermined by the chemica!-specific sail saturatipn limit(C�J which is used to screen for the presence of non-aqueous phase liquids(NAPLs). As indicated in Section 4.2.3, in sitttations where � � the residu::! c�oncentration af a compound that is a iiquid at ambient soil temperature exceeds Cs,r the compound may exist as free-phase liquid (see Exhibit C-3 in Appendix C �fcr a list of those � corr�pounds present in liquid phase at typical ambient soil temperaiures). In t�iese cases, further : investigatian will be rec�uired. The finai two columns in Exhibits A-1 tltrougE�A-3 present generic SSLs for the migratian � to ground water pafhway. The;eneric commercia!/industrial SSLs for this pathway are the same as th�se for residentia! use and are unchanged from ti�e 1996�SSG. As discussed in Section 4.2.3, this approach protects �otential potable ground water resources that may be present beneatll sitzs with commercial/industrial uses and protects of£site residents who may ingest ground water contaminated by the site. The mib ation eo ground water SSLs are back-calculated fi•om a�i acceptable target soi) leachate concentration using a difution-attenuation factor(DAF). The first of the two coluinns of SSLs for this pathway presents levels calculated using a DAF o#'20 to account I . for reduc[ions in cor�taminant concentration due to natural processes occurring in the subsurface. The secand column presents SSL values for the migration to ground water pathway ca}c��lated assuming a DAF of one {i.e.,no dilution or atienuation between the source and the rec�ptor well). , These [eveis should be used at sites where little or no dilution or attenuation af soil ]eachate concentrations is expected; this will be the case at sites with characieristics svch as shallow water � � tab[es,fractured media, i�arst toPo�raphy, or source size greater than 30 acres. + � � The vapor intrusion spreadsi3eets can be found on EPA's web site at http://www.epa.gov/superfund/ programs/risk/airmodel/jahnson_ettinger.htni, � i l A-?

However, if commercial/industrial SSLs are used in soil screening evaluations, . _ elimination of an area from further consideration is contingent on an analysis of institutional cantrol options. Users should consult Section 4_3.2 of the guidartce document for more information. . The fina!exhibit in this appendix(Exhibit A-4)presents the default values for physical site clzaracteristics that are used in calculating SSLs(both residential and eotnmereial/indusirial)for the � inhatation and migration #o ground water pathways. These values describe the nature of the . . contaminant sflurce area,the charaeteristics of site soit,meteorologic conclitions, and hydrogeoiogic characteristics, and serve either as direct input parameters for SSL equations or as assumpti�ns-for ( ; develaping input parameters for the equations. � This appendix does not include SSLs for lead, dioxin, or PCBs, because EPA has issued � � separate documents that specify risk-based concentrations for these cantaminants in�soil.
