42、ty of water to be expected at that depth. (The Post, or Resident Engineers office, or local USGS office is a good source for this information.) This knowledge is necessary to estimate well drilling costs and to determine what type of treatment is required to make the water usable. Any such site-spec
43、ific conditions or criteria for individual projects should be included in this paragraph. The geologist must ensure that well design meets or exceeds Federal, state, and local installation requirements. Additional criteria may apply for wells at radioactive, mixed, biological, solid, or medical wast
44、e sites. Guidance on water well construction may be found in Environmental Protection Agency (EPA) Manual of Water Well Construction Practices (570/9-75/001).*The well shall be located as shown where directed, and be constructed in accordance with these specifications. Each well shall be installed to prevent aquifer contamination by the drilling operation and equipment, intra- and inter-aquifer contamination, and vertical seepage of surface water adjacent to the well into the subsurface, especially the well intake zone.1.3.1 Notifica
