Well Installation Sample Clauses

Well Installation. .1 The xxxxx have been completed in accordance with all regulations of PEI Dept. of Fisheries, Aquaculture and Environment, Water Resources Division.

Well Installation. Four observation xxxxx at the Mobile test site were designed to provide two distinct environments for construction and development studies. Two of the xxxxx (Figure VI-2) were deep xxxxx and were installed to depths of 60 m, with fully- penetrating screens in the confined zone between 40 m and

Well Installation. The following pay items will be used to CONVERT a soil boring into a well. These pay item costs do NOT include the cost of drilling of the borehole which is covered under the Drilling and Boring pay items. All xxxxx will be authorized by the DEP and shall be constructed in accordance with the Petroleum Restoration Program procedure PCS-006, Design, Installation, and Placement of Monitoring Xxxxx and other applicable guidance. NOTE: Underground injection xxxxx, including air sparge xxxxx, are exempt from Water Management District permit fees pursuant to Chapter 373, F.S., and are permitted by the DEP technical approval order. Where such exemptions exist, permit fees are not required and will not be reimbursable under this contract. Unless otherwise specified, the following pay items INCLUDE:

Well Installation. Each test well was to be advanced into the top of the till so that the bottom of the well screen was located below the top of the till. The test xxxxx were installed by first driving a pilot rod into the sediment until that pilot rod reached refusal/till. The pilot rod was then withdrawn from the sediment and the test well was then driven down the pilot hole until refusal/till was reached. The depth at which the pilot rod encountered significant resistance was recorded and is depicted on the well construction logs provided in Appendix A as “2010 Resistance”. Approximately 5-feet of riser pipe was left exposed above water surface at the time of installation. The top of casing elevation and horizontal global positioning system (GPS) coordinates were collected at each well after installation. Each monitoring well was developed using a “surge and purge” method. The xxxxx were surged using a polyvinyl chloride (PVC) surge block and then purged using a submersible pump. Each well was surged and purged until the purge water ran relatively clear (low turbidity). Phase I to install one test well in SMAs 2 through 6 (Recovery Test Xxxxx (RTW) 1 through 5) was conducted on November 8 and 9, 2010. One additional test well was installed in SMAs 2 through 5 during Phase II well installation, which occurred during November 16, and 17, 2010.

Well Installation. Following the direct push and communication with the RWQCB, the next phase of site investigation would likely be installation of additional groundwater monitoring xxxxx. The existing monitoring xxxxx at the site are 30 or 32 feet deep and we assume that the new monitoring xxxxx would be constructed in a similar fashion. Assuming hollow-stem auger drilling techniques are appropriate for the site and that the completed groundwater monitoring xxxxx would be 2-inch diameter, Schedule 40 PVC xxxxx, with a well screen, the estimated driller’s cost to install one well is about $3,000. Including Geosyntec oversight and well development, the cost to install two groundwater monitoring xxxxx at the same time would likely range between $12,000 and $15,000. This estimate does not include or sampling the xxxxx. and It is likely that the RWQCB will require documenting the site investigation activities and on-going communication during the site investigation activities. Reports documenting the direct push and well installation could range between $5,000 and $10,000 each. Groundwater monitoring data from the new monitoring xxxxx will be included in routine groundwater monitoring reports and is not included in this scope. Communication with the RWQCB is hard to predict; up until now, there has been very little communication between the County, Geosyntec and the RWQCB. However, it is likely that meetings and phone conferences will be necessary to negotiate the scope of the site investigation and subsequent remedial alternative The communication costs may range between $4,000 and $8,000.
