ABSTRACT
Groundwater control operations, whether using pumping or exclusion methods, have the potential for causing adverse impacts on the ground water environment. These impacts may, in some circumstances, extend for some considerable distance beyond the construction site itself. In many cases, this will not cause problems, but there are situations when the poten tial impacts may be significant enough to merit careful monitoring and, if necessary, mitigation. This chapter outlines some potential environmental impacts that can result from groundwater control, the conditions in which they may occur, and possible mitigation measures.
