Chapter 10 covers groundwater chemistry. It begins with a review of water’s molecular properties and aqueous chemistry units. The natural chemistry of various groundwaters is discussed and compared to other natural waters. Isotopes of hydrogen and oxygen are discussed along with their ratios in different natural waters. Radioisotopes and water age dating techniques based on them are discussed. Three case studies illustrating the natural chemical evolution of groundwater are presented: the regional scale in the Floridan aquifer, the local scale in the Floridan aquifer, and the Milk River aquifer.

None of the three elements is particularly abundant in the earth’s crust although several minerals contain them as major constituents. Antimony has two stable isotopes. Arsenic, antimony, and bismuth each exist in several allotropic forms.

There are three crystalline forms of arsenic, of which the ordinary, gray, metallic, rhombohedral α-form is the stablest at room temperature. Antimony exists in five forms in addition to the ordinary α-form. The chapter describes the physical properties of the α-rhombohedral form of arsenic, antimony, and bismuth. It also discusses the chemical reactivity and group trends of arsenic, antimony, and bismuth.
