Comprehensive information on the behavior of most inorganic chemicals in groundwater is limited. Agriculturally important compounds have been studied for many years; however, inorganic compounds such as metals have only recently begun to attract widespread interest as ground-water and soil contamination become a concern. This section illustrates some of the most important processes for several groups of inorganic contaminants and the impact of these processes on the concentration and mobility of contaminants.
Inorganic constituents in the subsurface environment can be classified into the following four categories: nutrients, acids and bases, halides, and metals. The origin and sources of these inorganics are discussed in Section 9.11.
