TEST WELL DRILLING, CONSTRUCTION, SAMPLING The following tasks describe the Consultant’s efforts during the drilling, construction, testing and sampling of the test well. The goal of this task shall be to test the specified location for a production well that shall yield an acceptable and reliable quantity of groundwater with suitable water quality. Additionally, this task shall produce the necessary data that is required to design the production well. The data that shall be obtained during the construction of the test well is to include geophysical logs, formation samples, aquifer water quality, water level records, (static and pumping water levels), sanitary seal depth, intermediate seals(s) depth, well screen locations, and any other data or information deemed necessary by the Consultant. Task 1.0 – Develop Drilling Work Plan / Acquire Driller The Consultant shall develop a “Work Plan” and subcontract with an experienced and qualified well drilling contractor who will execute the “Work Plan” to drill, test and sample the test well. The “Work Plan” shall include Special Provisions and Technical Specifications. Special Provisions shall be developed to address site specific conditions such as: Construction water availability Site security Noise suppression Fluid/waste disposal Site restoration Other site-appropriate contractor requirements Technical specifications will be created and integrated with the City’s standard boilerplate construction bid documents.
