Task 2 — Off--Site Access and Right of Way (ROVA Notification Packages The two monitoring wells proposed to be installed under Task 3 (below) are located off property (to the west of the site). One of the monitoring wells is located in a Florida Department of Transportation (FDOT) ROW, on the south side of State Road 510, and the other monitoring well is located on the adjacent private property to the west. Obtaining access to install the monitoring well along the roadway will require preparing and submitting a ROW Notification ! package, which includes a request for a general use permit, to the FDOT (Treasure Coast Operations). Obtaining access to install the monitoring well located on the adjacent private property will require IRC to submit an offsite access agreement with the owners of the property and have it approved prior to installation and sampling activities. Task 3 — Monitorine Well Installation Task 3 consists of a single mobilization to the site to install monitoring wells. Geosyntec proposes to install two monitoring wells using direct push technology (DPT) drilling techniques at the locations presented in Figure 1 . The monitoring wells will be constructed of 14nch PVC and will be installed to a maximum depth of 15 feet below land surface (ft BLS) with 10-ft of 0.006-inch slotted screens with a 30/65 pre-packed sand filter. The monitoring wells will be completed with the 24-inch by 24-inch concrete pad with a 44nch PVC casing that will be approximately Meet above land surface. Once installed, the monitoring wells will be developed until visibly free of particulate matter. Geosyntec assumes one day of oversight for the monitoring well installation and development. Surveying (location, top-of-casing and ground elevations) of the newly-installed monitoring wells will be also completed. Task 4 — Monitoring Well Sampllne Following installation, the .newly installed monitoring wells will be purged and sampled in general accordance with FDEP Standard Operating Procedures (SOPs). The collected groundwater samples will be laboratory analyzed for arsenic by EPA Method 6010. In addition, water levels will be collected from the newly installed monitoring wells and the existing site monitoring wells to document the groundwater elevations and flow direction at the site. The current cost breakdown of the monitoring well installation assumes only two monitoring wells will be required to document delineation of the arsenic groundwater impacts. An additional 100% contingency has been added to Task 3 and Task 4 to cover any additional XR13013=R13W2.D0C F 11 engineers I scientists I innovators
