Work will generally include but is not limited to: drilling two 6-inch drinking water wells up to 150 ft. deep; providing two 10-inch outer casings for grouting 30 ft. deep each well; performing flow and recovery testing; taking sieve samples for new well screens, purchasing and installing; performing NYS DOH certified lab testing of each well. Each bid must be accompanied by security in an amount not less than five percent (5%) of the amount of the bid. Bidders are responsible for the timely delivery of their bid proposal to the proper person and location. The Contractor must comply with relevant state and federal wage rates, provide proof of registration with the New York State Department of Labor, and ensure all site laborers, workers, and mechanics have completed the OSHA 10-hour construction safety and health course.

Work will generally include but is not limited to: o Drilling Two 6-inch Drinking Water Wells up to 150 ft. deep: o Provide two 10-inch outer casings for grouting 30 deep each well o Perform Flow and Recovery Testing o Take Sieve samples for new well screens, purchase and install o Perform NYS DOH certified lab testing of each well o Completion Date: July 31, 2026 Phase I: Drill 6" casing with a 10" outer casing, Develop, Pump Testing, NYSDOH Required Testing, Water Quality Testing for Two New Wells o Drill and grout in place 30 feet of 10-inch diameter (minimum) outer steel surface casing for each well. Locations will be determined by The Engineer. o Drill and install a 6-inch diameter steel cased well to a maximum depth of 150 feet bgs. Provide a per ft price should the well be shallower or deeper than 150 feet bgs. o The proposal must describe the proposed method of drilling and well construction. o Representative soil samples must be collected at a minimum of 5-foot intervals or more frequently as directed by the drilling inspector/project Engineer through the proposed screened interval. o Soil samples will be collected by the driller and analyzed for grain size distribution. o Install a well screen designed with screen opening(s) to match the glaciofluvial sandy gravel formation in each production well. The final screen zone (depth) will be determined by the screen vendor and engineer/geologist. The screen design will be approved by the project engineer before the screen is ordered. The target water production rate is 50+ gpm for each well. o Perform well development until turbidity isless than 1 NTU. The contractor bid should clearly state the number of assumed hours for well development. Assume 24 hours minimum per well and include an hourly rate for well development, this rate will be used if any additional development is needed. The Contractor shall state what method they will use to develop the Wells o Provide all labor, equipment, and materials to perform consecutive 24-hour constant rate pumping tests, one in each well, including recovery tests. Allow a minimum of 24 hours for full recovery of the aquifer between the first and second pumping tests. o Perform recovery tests for 12 hours after the 24-hour pumping test is completed in each production well, or until the water level in the pumping well recovers to within 90 percent of the initial static water level, whichever is less. o Furnish and install a temporary pump, piping, hoses, gauges, meters, electrical, still pipe, sample port, etc. to perform the 24-hour constant rate pumping tests and recovery tests in both production wells. Provide sufficient discharge hose/pipe to discharge water up to 200 feet away from the pumping well. The target constant pumping rate is 50 gpm. The pumping rate may be adjusted based on actual drawdown during the test. o Provide experienced personnel to operate and monitor all equipment during the pumping test. o The Contractor will be required to collect and have water samples analyzed by a NYS DOH approved Laboratory. To Include sampling and analysis for all inorganic chemical, organic chemical, and radiological parameters as well as microbiological contaminants as listed in 10 NYCRR Subpart 5-1 and to include, PFOA/PFOS, 1,4-Dioxane, DBCP and EDB. o Provide temporary fencing (e.g. construction fencing) to enclose the work zone prior to initiating drilling activities and maintain until equipment is demobilized. In addition to the above tasks, the cost to Purchase and install a Pitless Unit must be included in the bid as a separate line item. The Pitless Unit must meet NSF 61 NYS DOH requirements. This work would be performed under a separate mobilization at a later date after well permitting is completed. The Town will be responsible for retaining a separate contractor to perform the excavation for the pitless unit installation.
