Groundwater Level Monitoring Network 2026 Bedrock Monitoring Well Installation Project

April 21, 2026

PROJECT OVERVIEW

The New Hampshire Geological Survey (NHGS), a unit within the New Hampshire Department of Environmental Services (NHDES), is seeking bids for the installation of eight (8) bedrock monitoring wells to be located throughout the State of New Hampshire. The newly installed wells will be incorporated into the New Hampshire Groundwater Level Monitoring Network, which monitors groundwater level variations as indicators of drought and water resource availability across the State.

Prospective bidders may provide bids on any subset of the eight bedrock well installation locations included in this Invitation to Bid document. Providing a bid on all bedrock well installation locations included in this invitation to bid is not required for bid consideration. However, provision of bids on a minimum of four of the eight (4 of 8) bedrock well installation locations is required for consideration.

The locations of the eight bedrock well installation locations are in the towns of: Bath, Concord, Errol, Exeter, Franklin, Lebanon, Lyndeborough, and Walpole, New Hampshire.

The bedrock wells are to be drilled using rotary drilling techniques to install the boreholes into bedrock. Permanent steel casing minimum 6-inches in diameter will be installed through the overburden above bedrock, as well as a minimum of 10 feet into competent (un-weathered) bedrock.

The permanent steel casing will be cement grouted into competent bedrock and left to cure overnight.

Final depth of the bedrock wells will be determined during drilling based on field observations of groundwater conditions but are anticipated to be approximately 500 feet total depth below ground surface. Once drilled, the bedrock portion of the wells will be left as open boreholes with no screen or internal casing installed. After completion of the drilling of the wells, the contractor will pump the wells by air-lift method to develop and determine the yield of the wells. The contractor will provide Royer-type locking caps to be installed at the top of the steel casing. Site preparation, best management practices for fluid and sediment runoff control measures, and site restoration will be performed by the contractor. No well pumps, water piping, or utility trenches will be required for the bedrock wells. The wells will be installed by a licensed New Hampshire water well contractor in good standing in

Groundwater Level Monitoring Network Contractor Initials ________ 2026 Bedrock Monitoring Well Installation Project Date ________ adherence to all applicable New Hampshire laws and rules. A water well contractor holding a technical drilling license is preferred but not required for consideration.

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 equipment 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, decided in consultation with the GEOLOGIST. Once competent bedrock is encountered, the contractor will then advance a pilot borehole measuring 8-inches or greater diameter a minimum of 10-feet into competent, un-weathered 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

Groundwater Level Monitoring Network Contractor Initials ________ 2026 Bedrock Monitoring Well Installation Project Date ________ 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, including: excavation of mud pits as needed to contain drilling fluid and cuttings; and dissipation and infiltration of drilling spoils. Any excavations dug for drilling fluid and cuttings 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.

9.3.1 Additional Environmental Protection Measures for Concord Drill Site The CONTRACTOR shall take additional environmental protection measures at the drilling site in Concord to prevent drilling fluid, drilling mud, or drilling cuttings from migrating into the area surrounding the drilling site. Additional environmental protection measures shall include the use of silt fencing around the drilling site and containerization and haulage of spoils if on-site containment of fluids and cuttings is not feasible.

9.4 Sampling Procedures, Preservation, and Labeling Requirements Drill cutting samples shall be collected at 20-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.

Groundwater Level Monitoring Network Contractor Initials ________ 2026 Bedrock Monitoring Well Installation Project Date ________

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

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.
