David Relos August 30, 2011 Page 4 of 6 overnight delivery) under chain -of- custody procedures. Analysis will also include the analysis of a water sample for QA/QC purposes (Volatile Organic Compound only). Wightman Petrie will plug the boreholes /wells with bentonite once soil and groundwater sampling activities have been completed. Reporting Upon receipt of the laboratory analyses, data will be reviewed and tabularized. Comparison of the data for each respective chemical constituent will be made to the Risk Integrated System of Closure (RISC) Default Closure Values for Residential and Industrial /Commercial Properties. Upon completion of the initial data review, a "Letter Report" will be prepared which presents the sample collection and analytical methodologies used during the field phase of the assessment. Copies of the sample location maps, tabulated data and comparison to RISC Default Closure Values will also be incorporated. Recommendations for any additional assessment activities will be made for review and comment. SCHEDULE Wightman Petrie proposes to commence site investigation activities within one (1) week of receipt of notification to proceed, depending on weather, utility clearance and Geoprobe availability. Once a specific date for the field component of the Phase II has been established, Wightman Petrie will notify the client. Upon mobilization, we anticipate completion of the Geoprobe sampling requiring one (1) day. Should less field time (i.e., 'h -day of Geoprob) be required; you will be billed accordingly. Laboratory analyses will be completed by Pace Analytical on standard one -week turnaround from receipt by the laboratory. Our initial discussion of results will occur within one (1) day of receipt of laboratory analytical results. Our written "Summary Letter Report" will be submitted within one (1) week of the initial conference. COST ESTIMATE An ESTIMATED COST for Phase II Environmental Assessment Services is presented as follows: Field Engineering Services /Project Management Limited Ground Penetrating Radar Survey Geoprobe Rental (assumes 1 -day @ $1,400 /day, including mobilization) Laboratory Analysis: 8 soil samples for % Moisture @ $10 /sample 8 soil samples for analysis of BTEX constituents @ $65 /sample 8 soil samples for analysis of TPH -ERO @ $60 /sample 8 soil samples for analysis of carcinogenic PAHs @ $90 /sample 5 groundwater samples for analysis of Volatile Organics @ $95 /sample 4 groundwater samples for analysis of carcinogenic PAHs @ $90 /sample Reporting ESTIMATED COST $900 $300 $1,500 $80 $520 $480 $720 $475 $360 $1,200 $6,535 Please note that this ESTIMATED COST should be considered a Project Maximum, which Wightman Petrie will not exceed without prior approval. However, should the scope of services require modification (i.e., additional borings) based upon field conditions and /or circumstances that would not have otherwise been anticipated, Wightman Petrie will notify the client of such "changed conditions" and resultant cost implications to the project.
