If field conditions indicate the need to offset any BEDROCK WELL INSTALLATION Page 15 of 21 New Hampshire Geological Survey Groundwater Level Monitoring Network Contractor Initials ________ 2024 Bedrock Monitoring Well Installation Project Date ________ from the planned location, the new conditions shall be approved by the GEOLOGIST before work is started at the offset location. 6. ABANDONED BORINGS Borings shall not be abandoned before reaching the final depth ordered by the DEPARTMENT except on the approval of the GEOLOGIST. No payment will be made for borings abandoned by reasons of error, accident, or negligence on the part of the CONTRACTOR. Borings abandoned prior to reaching required depth, caused by an obstruction or other reasonable cause beyond the control of the CONTRACTOR such that a boring cannot be completed, shall be replaced by a supplementary boring sited adjacent to the original and driven to the required depth. Penetration of the supplemental boring to the completed depth of the original boring may be made by any specified means selected by the CONTRACTOR and approved by the GEOLOGIST. Samples shall be taken in the supplementary boring from the elevation at which the original boring was abandoned in a manner specified for the original boring. No payment will be made for any work on an abandoned boring. 7. SEALING BORINGS The CONTRACTOR shall be responsible for the sealing of all completed borings, as per the acceptable methods specified in the New Hampshire Water Well Board Code of Administrative Rules, Chapter 600, Part We-604, Section We-604.05. The CONTRACTOR shall be responsible for addressing any and all issues concerning compliance with these stipulated rules. 8. DEVELOPING BEDROCK WELL Once installed, the well will be pumped by air lift method to develop the well and remove fine sediments from the well. A minimum of three volumes of well water should be evacuated until the purged water is free of sediment. The total volume pumped for each well shall be at the discretion of the GEOLOGIST. 9. WELL DRILLING 9.1 Preferred Methods The CONTRACTOR shall prepare the drill site for access by the drilling rig and support vehicles using appropriate excavation equipment, as required. CONTRACTOR will mobilize to the site to commence BEDROCK WELL INSTALLATION. Drilling will begin by drilling a borehole through the overburden present above the bedrock using appropriate drilling methods. Once competent bedrock is encountered, the contractor will then advance a pilot borehole measuring 8-inches Page 16 of 21 New Hampshire Geological Survey Groundwater Level Monitoring Network Contractor Initials ________ 2024 Bedrock Monitoring Well Installation Project Date ________ or greater diameter a minimum of 10-feet into competent bedrock. Steel casing will be installed into the pilot borehole, cement grouted into place by tremie or force grouting methods, then left overnight to cure. The CONTRACTOR will then commence advancing the borehole into bedrock using air rotary methods to the final depth of the well, determined by the GEOLOGIST based on conditions encountered, but anticipated to be no more than 500 feet below ground surface. 9.2 Equipment Requirement The CONTRACTOR shall provide excavation machinery, drill rigs, drill bits, drill steel, and all other required equipment in quantities and sizes sufficient for work to be expedited. 9.3 Environmental Protection Measures The CONTRACTOR shall prevent the drilling fluid and/or drilling mud from migrating into waterways in the area surrounding the drilling site using established industry Best Management Practices. Any excavations dug for drilling fluid management shall be back filled, and sediment and erosion control measures shall be removed at the conclusion of drilling activities. The ground surface at the drilling site shall be leveled at the conclusion of drilling activities. No petroleum-based or Teflon-based lubricants will be allowed. Environmentally friendly EPA approved lubricants may be allowed at the discretion of the GEOLOGIST. 9.4 Sampling Procedures, Preservation, and Labeling Requirements Drill cutting samples shall be collected at 10-foot intervals while drilling through both overburden and bedrock, although sampling may occur at a greater or lesser frequency if dictated by stratigraphic or lithologic changes or as specified by the GEOLOGIST. Upon reaching a stratigraphic or lithologic change depth, drilling shall be stopped if determined by the GEOLOGIST to be necessary. Disturbed materials shall be removed from the hole by air lift for a period of time, and a clean sample of the bedrock cuttings shall be collected upon drilling recommencement. Upon removal from the borehole, a portion of the recovered sample shall be placed into a container provided by the DEPARTMENT. Each sample shall be labeled and cataloged by the GEOLOGIST. 10. LOGS, AND DATA AND SAMPLE DELIVERY 10.1 Boring Logs During the progress of each data collection operation, the DEPARTMENT will provide a GEOLOGIST to keep a log of all data collection and drilling operations. 10.2 Data and Sample delivery Page 17 of 21 New Hampshire Geological Survey Groundwater Level Monitoring Network Contractor Initials ________ 2024 Bedrock Monitoring Well Installation Project Date ________ All data from samples collected as described in Section 9.4, in addition to any soil or rock cutting samples shall collected and transported by the DEPARTMENT. 11. CLEAN UP, SITE RESTORATION The CONTRACTOR shall clean up and leave all work sites in a neat and workmanlike manner, to the satisfaction of the GEOLOGIST. The CONTRACTOR shall exercise every caution in not damaging property, and shall repair any damage that may occur. Any property damage resulting from the CONTRACTOR’s work shall be immediately reported to the GEOLOGIST. On completion of work at a specific location, the CONTRACTOR shall remove all equipment, materials, spoil, brush, and distribute or bury all drill cuttings. All boreholes shall be sealed prior to worksite departure, as specified in Section 7. No holes, depressions, cracks or protrusions resulting from the work and which is unsightly or could present a public hazard shall remain. The CONTRACTOR will restore any pre-existing drainage control features that were modified to allow access for the drilling rig and support vehicles. The CONTRACTOR may be recalled to any site, during the one-year period following completion of the work, to repair surface settlement or cracks that develop in the work area. The CONTRACTOR shall not be compensated additionally for return site visits for clean-up, filling of holes, or other site restoration.
