GEOSYNTEC CONSULTANTS <br /> Janet B . Dunlap , P . E . <br /> 18 March 2005 <br /> Page 2 <br /> We have developed a task-based approach to group field activities and accomplish <br /> this work in an organized and cost- effective manner. The remainder of this letter <br /> provides a description of the proposed scope of work and a budget estimate to <br /> accomplish the work described herein (Attachment A) . <br /> PROPOSED SCOPE OF WORK <br /> Task 1 . Field Work Preparation <br /> Prior to initiating field activities, GeoSyntec will prepare a Site- Specific Health & <br /> Safety Plan (SSH& SP) , in accordance with the requirements of 29 CFR Part 1910 . <br /> Additionally, GeoSyntec will procure the drilling subcontractor, collect and organize <br /> the field sampling equipment, and coordinate the field work with IRCFM personnel . <br /> Task 2 . Field Activities <br /> Based on GeoSyntec ' s understanding of the work, we propose to complete the <br /> following tasks : <br /> • Using direct push technology (DPT) drilling equipment, GeoSyntec proposes to <br /> install two , 1 -inch diameter monitoring wells to an anticipated total depth of <br /> approximately 15 ft below land surface (BLS) , with 10 ft of 0 . 010 - inch slotted <br /> screen with a 20/40 pre-packed sand filter pack (groundwater noted in CAR at <br /> approximately 6 '/z ft BLS) . One monitoring well will be installed in the vicinity <br /> of the former fuel pumps and one monitoring well will be installed in the center <br /> of the former UST area. The monitoring wells will be completed with 24-inch <br /> by 24-inch concrete pads and 8 -inch diameter steel manholes . Following <br /> installation, each well will be developed until visibly free of particulates . <br /> Approximately 24 hours following monitoring well installation, the monitoring <br /> wells will be purged and sampled in accordance with Florida Department of <br /> Environmental Protection Standard Operating Procedures . Collected <br /> groundwater samples will be laboratory analyzed for volatiles by EPA Method <br /> 8021 (BTEX/MTBE) , polynuclear aromatic hydrocarbons (PAHs) by EPA <br /> Method 8310 , and total recoverable petroleum hydrocarbons (TRPH) by FL- <br /> PRO . <br /> • Soil hand auger returns will be collected from the ground surface to the water <br /> table (monitoring well locations and up to 10 additional soil boring locations) . <br /> Soil samples collected will be screened using an organic vapor analyzer (flame <br /> XR050023/XR05XXXX/IRC —Limited Petroleum Site Assessment <br />
