Abstract:

Urban groundwater control requires high levels of skill and experience but allows for only a small margin of error. Determining the best method for controlling groundwater requires knowing the characteristics of the site. In urban areas, underground structures, pipes, subways and sewer lines can all interfere with groundwater control. Contamination can also make controlling groundwater difficult. Of the four basic methods of groundwater control�open pumping, predrainage, cutoff and exclusion�the best solution may be a combination of two.
