This section focuses on environmental conditions that may result in physical or chemical incompatibilities between wastes and reservoirs. Determining the potential for incompatibility is a part of the geochemical fate assessment that must be undertaken for any injection project because of possible... 

Each interaction involves numerous chemical processes. The dominance of a specific interaction depends on the type of waste, the characteristics of the brine and rock in the reservoir, and environmental conditions. Table 20.14 describes some of the more common processes that may result in incompatibility. 

The thermodynamic incompatibility of many of the solid phases present with each other as well as their local environment, results in formation of secondary minerals. Although the secondary materials may comprise only a small volume fraction of the waste, they (1) tend to increase in amount with time, as weathering processes proceed, (2) typically form at grain surfaces and are thus physically liable to react with percolating gas or liquids, and (3) may exhibit sites suitable for sorption or crystallo-chemical incorporation of trace elements (see Donahoe, 2004). Frequently observed secondary minerals include jarosite and ettringite the former is known to sorb ions such as Mn and As, whereas ettringite can form solid solutions, in which SO4 is replaced by Cr04 (Kumarathasan et al. 1990).

Safe storage practices should be applied to various types of wastes. Storage procedures are intended to prevent incompatible materials from coming into direct contact with each other and to isolate such materials from sources of ignition, such as smoking and open flames. The chemical and physical properties of the materials, the quantities of the materials, and the packaging systems employed will determine the extent of isolation or separation. However, it is always advisable to seek the recommendations of the supplier to obtain more in-depth information concerning incompatible materials with which the chemical should not be stored. 

When you are faced with the problem of coming up with a reasonable structure to match some spectroscopic or chemical data, it is possible to waste a lot of time writing answers that are incompatible with the molecular formula of the molecule. Determining the number of rings -I- tt bonds ahead of time (the degree of unsaturation) can make solving these problems go much more smoothly You automatically know whether or not you need to consider these structural elements as possible parts of an unknown molecule. 

Other useful safety-related information is normally provided as well, such as the flash-point (if applicable), fire extinguisher type (if applicable), first aid and medical advice, a color code to aid in avoiding incompatible storage, and standard identifiers, such as a CAS number which can aid in referring to a MSDS data base, and a UN number which is needed in disposing of the chemical as a hazardous waste.
