Mr. Mike Nixon Geosyntec <br /> 30 November 2009 consultants <br /> Page 3 <br /> Task 1 — Preliminary Activities <br /> Task 1 includes project management for the entire project, as well as all preliminary activities <br /> associated with securing project costs from subcontractors and updating the Site- Specific Health <br /> and Safety Plan to cover the additional assessment activities . Specific activities include : <br /> • Updating the existing OSHA-required, Site- Specific Health and Safety Plan; <br /> • scheduling a utility locate, acquiring field equipment (pumps, water quality meters, <br /> calibration solutions, sampling containers , etc . ), subcontracting; and <br /> • project planning and management responsibilities, invoice review, project coordination, <br /> and project administration. <br /> Task 2 — Monitoring Well Installation Activities <br /> Task 2 consists of mobilizing to the site, installing and sampling monitoring wells, and collecting <br /> a soil core for lithologic characterization. Geosyntec proposes to install six monitoring wells <br /> using direct push technology (DPT) drilling techniques at the locations presented on Figure 1 . <br /> The monitoring wells will be constructed of 1 - inch PVC and will be installed to a maximum <br /> depth of 15 feet below land surface (ft BLS) with 10-ft of 0. 010-inch slotted screen with a 20/30 <br /> pre-packed sand filter. The monitoring wells will be completed with a 24-inch by 24-inch <br /> concrete pad with an 8 -inch manhole . For the monitoring wells located in the wooded area, the <br /> wells will be completed with the 24-inch by 24-inch concrete pad with a 4-inch PVC casing that <br /> is approximately 3 - feet tall (instead of the 8 -inch manhole) . Once installed, the monitoring wells <br /> will be developed until visibly free of particulate matter. <br /> Following installation, the newly installed monitoring wells and existing site monitoring wells <br /> will be purged and sampled according to FDEP Standard Operating Procedures ( SOPS) . The <br /> collected samples and one quality assurance sample (duplicate) will laboratory analyzed for <br /> arsenic by EPA Method 6010 . In addition, water levels will be collected from the newly <br /> installed monitoring wells and the existing site monitoring wells to document the groundwater <br /> elevations and flow direction at the site . <br /> Surveying (location, top-of-casing and ground elevations) by a licensed professional land <br /> surveyor of the newly-installed monitoring wells and the current site monitoring wells will be <br /> also completed . <br /> XR09305/CCR09 ] 08 .
