ACS Journals CAS About Us ... Press Room You Are Here: Home Careers What Chemists Do Careers in Chemistry Geochemists Use Chemical Information Found In Rocks A wealth of information is buried in the liquids, gases, and mineral deposits of rock. Geochemists must understand this information and use it to make decisions about a range of industrial and scientific research applications. Understanding the chemical composition of rocks tells oil companies where to drill for oil, enables scientists to put together broad-based theories about the way the earth is changing, helps environmental management companies decide how to dispose of toxic or hazardous substances, and steers mining companies toward using natural resources with a minimum environmental impact. Provide Help for The Environment Consider, for instance, the work of a scientist who specializes in aqueous geochemistry for the U.S. Geological Survey (USGS). Such a geochemist focuses on the chemistry part of geology problems—specifically, the interactions between water and rock that relate to mining activities. When minerals once buried in mountains are exposed to oxygen and water, they begin to break down more rapidly, making metals more readily available to become part of the water system in the environment. Mining activities exacerbate this process. They also often result in abandoned mine waste piles, which frequently contain sulfides—a key player in creating acid mine drainage. When rain falls or snow melts, acidic, metal-rich water drains off the waste piles. Since mines are in the mountains, their wastewater tends to drain into the headwaters of river systems. These contaminated streams can impact aquatic, animal, and human life because the water is frequently diverted for irrigation and well water in rural areas downstream. As a result, the effect of acid mine drainage on the environment has raised great concern.

52. GEOCHEMISTRY OF ARSENIC Finally, geochemical data (including the speciation data) and information from existing interpretive reports are used to construct preliminary hypotheses http://or.water.usgs.gov/pubs_dir/Html/WRIR98-4205/as_report6.html

Arsenic in Ground Water of the Willamette Basin, Oregon GEOCHEMISTRY OF ARSENIC Sources of Arsenic Review of Geochemical Processes Controlling Arsenic Mobility Two categories of processes largely control arsenic mobility in aquifers: (1) adsorption and desorption reactions and (2) solid-phase precipitation and dissolution reactions. Attachment of arsenic to an iron oxide surface is an example of an adsorption reaction. The reverse of this reaction, arsenic becoming detached from such a surface, is an example of desorption. Solid-phase precipitation is the formation of a solid phase from components present in aqueous solution. Precipitation of the mineral calcite, from calcium and carbonate present in ground water, is an example of solid-phase precipitation. Dissolution of volcanic glass within an aquifer is an example of solid-phase dissolution. Arsenic adsorption and desorption reactions are influenced by changes in pH, occurrence of redox (reduction/oxidation) reactions, presence of competing anions, and solid-phase structural changes at the atomic level. Solid-phase precipitation and dissolution reactions are controlled by solution chemistry, including pH, redox state, and chemical composition. Adsorption and Desorption Processes Arsenic is a redox-sensitive element. This means that arsenic may gain or lose electrons in redox reactions. As a result, arsenic may be present in a variety of redox states. Arsenate and arsenite are the two forms of arsenic commonly found in ground water (Masscheleyn and others, 1991). Arsenate generally predominates under oxidizing conditions. Arsenite predominates when conditions become sufficiently reducing. Under the pH conditions of most ground water, arsenate is present as the negatively charged oxyanions H2AsO4- or HAsO42-, whereas arsenite is present as the uncharged species H3AsO30 (Hem, 1985). The strength of adsorption and desorption reactions between these different arsenic species and solid-phase surfaces in aquifers varies, in part, because of these differences in charge. Differences in species charge affect the character of electrostatic interactions between species and surfaces.

OVERVIEW EXPLORATION GEOCHEMISTRY Petroleum exploration surface geochemical surveys can be used to map the light hydrocarbons expressed through microseeps from active petroleum and natural gas reservoirs at depth. The maps, developed from the survey, serve as a guide to identifying prospective areas in both frontier and mature basins. The light hydrocarbons, when surveyed, analyzed and mapped, using ETI's proven techniques and technology, produce a graphic, geochemical picture of the source rock below. This picture shows whether or not a given area contains petroleum source rocks; whether the area is more oil or gas prone; and finally, whether or not the gas is over cooked and non-productive, or the oil too heavy to produce by drilling alone. Such studies can greatly reduce the area to be searched; helping to focus more expensive exploration techniques, such as 3D geophysical surveys, on those portions of the basin most likely to contain petroleum accumulations and potential reservoirs.
