Industrial discharges, urban activities, agriculture, groundwater pumpage, and disposal of waste all can affect groundwater quality. of contaminated ground water is usually expensive, and sometimes a contaminated water supply must be abandoned and a new supply located. Preventing contamination before it occurs is the best solution. Because ground water contamination can have such serious consequences, many citizens, as well as local, state, and federal agencies, are taking. Contaminants present in these surface waters can contribute contamination to the ground water system.
