Abstract
“A geochemical study of the residuum of Callaway County, Missouri was conducted in order to better understand the properties affecting adsorption behavior in the subsurface. The following parameters were determined: grain-size distribution, soil pH, clay mineral type and quantity, iron and manganese oxide content, total organic carbon (TOC), and cation exchange capacity (CEC).
Ordovician, Devonian, Mississippian, and Pennsylvanian age residuum, along with Pleistocene age alluvium, loess, and glacial till were collected from rock quarries within the county. All samples were wet-sieved and the soil pH determined for each total sample. Clay mineralogy was ascertained from the minus 6 micron fraction.
A wide range of clay minerals are present; kaolinite, illite, smectite, and illite-smectite mixed layer clays. Iron and manganese oxide contents ranged from 0.14 to 2.87% and 0.00 to 0.08%, respectively, while TOC values ranged from 0.03 to 3.00%. The resulting variations in these parameters is reflected in the wide variety of CEC values, which ranged from a low of 5.15 to a high of 88.80 milliequivalents/100 grams. Alluvium had the lowest CEC (average 14.6 meq/100 g), the residual soils and loess were intermediate (average 17.8 and 26.8 meq/100 g, respectively), and glacial till had the highest CEC values (average 58.2 meq/100 g)”--Abstract, pages ii-iii.
