“…These data were of adequate sample density and analytical quality to characterize the geochemical landscape of the Animas River watershed. Geochemical data from small tributary streams from the USGS National Geochemical Data Base (Hoffman and Buttleman, 1994) were used to prepare regional geochemical maps of the Animas River watershed following the procedure outlined by Smith (1994). The details of the computational methods are in appendix I.…”

“…Geochemical map for copper (Cu) of the Animas River watershed. Data from the National Geochemical Data Base (Hoffman and Buttleman, 1994) was supplemented by samples from the major tributary streams during the 1995 sampling to evaluate the contributions of metals from the major tributary drainages in the Animas River watershed. Important tributary streams are labeled for reference; hydrology data are from USGS (1989); and the towns, railroads, and roads are from ESRI (1992).…”

“…National geochemical databases consisting of chemical composition of a grid of samples became available to the U.S. in 1994 (Hoffman et al, 1994) and in Chihuahua, Mexico, in 2001(SGM, 2001. Although these databases were originally intended for geochemical exploration purposes, they were later found to provide an inexpensive and accessible information source for conducting geochemical characterization (Borrego and Gutiérrez, 2000;Xuejing and Hangxin, 2001).…”

Geochemical processes contributing to the contamination of soil and surface waters in the Rio Conchos basin, Mexico

A geochemical characterization of the middle Rio Conchos basin is presented based on two contaminants, salts (Ca and Na) and toxic metalloids (As and Sb). Their content in surface water and sediment samples was determined, and their spatial distribution was mapped to show the relationship to each other, to the geology and hydrology, and to other potential factors affecting their distribution (i.e., prevailing winds). Correlation analyses between salts, toxic metalloids, and associated elements, and their spatial distribution aided in determining their sources, which included mines, rock outcrops, urban centers, irrigation waste water, and agricultural runoff. The salinity of the Rio Conchos reached a critical level after receiving waters of its contaminated tributary Rio Chuviscar and irrigation drain returns from the Irrigation District 005, but further downstream the water quality improved when it mixed with Ca-rich water, signifi cantly reducing its Na concentration. Based on its spatial distribution, the content of As in alluvial material was found to be associated with the presence of Ag-Pb mines and to a lesser degree to Oligocene ignimbrites. A correlation of As with Sb, Cu, and Bi suggests that natural sources are the dominant contribution of As within the area, although concentrations above permissible level for water were found in river water samples at a few places where sewage was also present, suggesting an additional (anthropogenic) important source of As. A characterization of natural sources affecting the chemistry of surface waters is a fi rst step toward understanding the natural processes taking place and for documenting natural background levels that are needed to predict the response of the environment to various human activities.

“…The NURE database was initiated by the U.S. Department of Energy in 1974 to obtain and compile geological and geochemical data for the evaluation of the extent and distribution of uranium resources in the conterminous United States (Hoffman, et al, 1994). Some years later, the concentration of Ͼ 59 different elements on stream sediments, soils, surface waters, and groundwaters was added to the database.…”

Maps showing anomalously high concentrations of 13 different elements in soils within the Mesa Quadrangle of southern Arizona were constructed using information contained in the National Uranium Resource Evaluation (NURE) database. Existing geochemical databases such as NURE provide an inexpensive and accessible resource that can be used to characterize an area geochemically. Anomalies in soils were determined after applying descriptive statistics, logarithmic transformations, elimination of outliers, and manipulation of below‐limit detection values. Among the elements with the most number of anomalies, Cu clustered in the southcentral part of the quadrangle where porphyry copper deposits are located, while As, Be, Co, Cr, Zn, Th, and U anomalies were located over exposed Precambrian and Tertiary igneous rocks. In general, anomalies could be related to the rocks cropping out, type of soils, and several mines present in the area.
