43. Acid Mine Drainage University of Waterloo research into groundwater geochemistry and remediation of acid mine wastes. http://www.science.uwaterloo.ca/research/ggr/MineWasteGeochemistry/AcidMineDrain

Remediation Department of Earth Sciences University of Waterloo Acid Mine Drainage Introduction The oxidation of sulfide minerals and consequent release of acid in tailings impoundments can last for decades to centuries. The interaction of the low-pH, metals and sulfate contaminated water with tailings and aquifer minerals initiates a sequence of pH-buffering reactions. This increase in pH is often accompanied by the precipitation of metal-bearing hydroxide and hydroxysulfate minerals that remove dissolved metals from the moving water. Research in our group has focused on the mechanisms and consequences of aqueous geochemical and mineralogical changes that occur within and below sulfide tailings impoundments. The research typically involves field and laboratory investigation, enhanced by groundwater flow, geochemical, transport and reactive transport modelling. The research has been collaborative with major companies in the Canadian mining industry, including Agnico Eagle, Falconbridge, INCO, Noranda and Placer Dome. Research assistance has also been provided from NSERC (Natural Sciences and Engineering Research Council of Canada)

Laboratory of Isotope Geochemistry Faculty, staff and students in the Laboratory of Isotope Geochemistry employ naturally occurring stable and radioactive isotopes as well as major element compositions to hydrological and geological questions. Study areas are generallylocal or in nearby hydrologic basins, and problems range from locations and extentof groundwater recharge to sources of chloride in brines. Students learn techniques of sampling and analysis of waters for tritium, radiocarbon and stable isotopes, andtheir interpretation. Recent studies have revealed sites of recharge in the Tucson Basin, and extent of migration of 1960's precipitation in local aquifers. Continuing studies detail the sources of chloride and sulfur in groundwater systems, the origin and evolution of chloride in sedimentary basins, and past solar activity inferred from high-precisionradiocarbon measurements in tree rings. Service analyses for internal and external users include radiocarbon dating, measurement of natural levels of tritium in water, stable isotope analyses of water,carbonates, brines, chloride minerals, sulfide and sulfate minerals.

60. GEOCHEMISTRY geochemistry. geochemistry is the application of chemical methodology andtheory to earth materials formed in the past or still forming today. http://www.science.uwaterloo.ca/earth/geoscience/chem.html

GEOCHEMISTRY Information on picture Geochemists help to solve earth science problems by using the physical and inorganic chemistry of major and trace elements in rocks and minerals and the organic geochemistry of hydrocarbon (coal, oil, gas) deposits. Geochemistry is the application of chemical methodology and theory to earth materials formed in the past or still forming today. There are two broad areas of interest. The first involves high temperature/high pressure geochemistry and is used in the study of the formation of minerals and rocks deep in the crust or in volcanoes. The second is low temperature geochemistry, and organic geochemistry. Here the geoscientist is interested in the behaviour of minerals or elements reacting under conditions near the surface of the earth. Most industrial and government geochemists are involved in the latter. Geochemical exploration methods allow prospecting for buried ore deposits by detecting trace amounts of metals and minerals in water, plant, soil, sediment and rock samples. By analysing quantities at the parts per million or even parts per billion level, geochemists can identify the "finger prints" of certain minerals and rocks carrying valuable metals. This can narrow the field area of detailed exploration and drilling. Glacial activity in Canada over the last two million years has "smudged the prints" making exploration more difficult and challenging to the exploration geochemist. Environmental geochemistry has become a vital skill for determining where man-made or natural distributions of elements can become a hazard in the environment. For example: the detection of mercury in lake or stream ecosystems and in assessing the dispersion of liquid radioactive wastes or toxic hydrocarbons (such as "coal tar") in groundwater. An important new area involves the study of chemical element distributions at the earth's surface, especially in water. This baseline information provides the foundation for environmental and health-related studies.
