June 15, 2020The largest extent of dewatering flows on the Delta Conveyance program construction sites would probably be from the vertical tunnel shaft locations, which would extend less than 200 feet below the ground surface. During design, soil investigations would be conducted that would include observations of groundwater levels and odors from the borings. If odors, especially due to high sulfide constituents, are present during soil investigations, the on-site dewatering treatment process would include methods to minimize noxious odors on adjacent properties.
