ABSTRACT
The contamination of groundwater resources has generated an industry with hydrogeologists, engineers, and environmental scientists involved in research and studies from environmental assessments through to design and installation of remediation schemes. Geochemistry and isotopes play an important role at all stages. Geochemistry and isotopes are used to trace both the origin and transformation of contaminants in groundwater, as well as predicting their fate and impacts on surface waters and water supplies. In this chapter, the major areas of application are examined, using the background on geochemistry and isotopes developed in the earlier chapters.
