PCA - Intersection of SR 60 and 43`d Avenue - 3 - Ardaman Proposal No. 12-3836 after additional data is gathered relative to groundwater levels and subsurface stratigraphy. The proposed shallow wells will be constructed of 2-inch diameter, 0 . 01 -inch slotted schedule . 40 PVC pipe . A summary of the proposed number and approximate location of the wells is provided in the following table . site Address (PrdArnky toAn ' Mterseddon) - ProAI posed Number and Location of WellsAn In Ann Mark's Mobil 4310 20"' Street (Northwest Comer) Two along 43rd Avenue and two along 20` ' Street Former Texaco / Lenny's Lounge 4315 20"' Street (Southwest Comer) Two along 43rd Avenue and one along 20'" Street Former FINA #6644/Mobil 4395 20'" Street (200 Feet West) Two along 20"' Street Former Union 76 4233 20"' Street (Southeast Comer) Two along 43rd Avenue and one along 20"' Street Cumberland Farms 1925 43rdAvenue (500 Feet South) Two along 43rdAvenue Indian River Farms WCD 4400 20'hStreet (Northwest Comer) One along 43rdAvenue and two along 20'" Street Quick Snack and Coin Laundry 4236 20'" Street (Northeast Comer) Two along 43rd Avenue and one along 20'hStreet Mermaid Car Wash 1935 43rdAvenue (450 Feet South) One along 43rd Avenue Strip Shopping Center 4201 - 4211 20"' Street (200 Feet East) One along 20"' Street (Vero Beach Dry Cleaners We note that permanent groundwater monitoring wells are not being proposed at this time since the locations will likely be disrupted during construction activities. Additional permanent groundwater monitoring wells may be proposed to monitor groundwater contamination levels and migration during construction if deemed appropriate based on the results of the PCA. C . Groundwater Sample Collection and Analysis Groundwater samples obtained from the wells will be collected for laboratory analysis in accordance with FDEP sampling requirements . Groundwater samples collected from the wells will be submitted to a State certified laboratory for analysis by EPA Methods 8021 and 8270, and the FL- PRO method . 11. Preliminary Contamination Assessment Report (PCAR) A report summarizing the above preliminary site assessment activities will be submitted upon completion of the above-described scope of work. Details , descriptions and rationales for the various site assessment activities will be presented , along with all data developed during the assessment activities . The report will include the results of our findings relative to any identified soil and/or groundwater contamination within the study area that may present limitations or require special monitoring of contaminated media during construction of the proposed intersection widening project. COST ESTIMATE This proposal contains general methodology and procedures for conducting a limited PCAR for the subject site . The quantity of items contained in this plan may vary depending on the findings during performance of the assessment (e .g . ; number of samples and wells, depths of monitoring wells , etc. ) . Consulting fees will be charged on a time and materials basis using the unit prices listed in this proposal . We have prepared the attached cost estimate for completing the scope of work as outlined above . The cost for these services will not exceed $60,748 . 50 without prior approval from the client.
