Hydrogeologic and geochemical studies of selected natural radioisotopes and barium in groundwater in Illinois. Research report No. 180 (final)

; ; ;

Dissolved concentration of the natural radioisotopes /sup 222/Rn, /sup 226/Ra, /sup 228/Ra, /sup 230/Th, /sup 232/Th, /sup 234/U, and /sup 238/U and the element Ba (/sup 2 +/) were investigated in a study of high concentrations of /sup 226/Ra, /sup 228/Ra, and Ba (/sup 2 +/) in groundwater from the Cambrian and Ordovician bedrock of northern Illinois. The high radium and barium concentrations are present in the major aquifers - the sandstone bedrock. Therefore, remedial well construction measures will not lower the concentrations. The combined concentrations of /sup 226/Ra and /sup 228/Ra range from 2.3 to 50.2 pCi/L; the majority of analyses exceed the drinking water reulations of 50.0 pCi/L. The high Ba (/sup 2 +/) concentrations occur in groundwater that is depleted in dissolved SO/sub 4//sup 2 -/ by anaerobic microbial reactions. A map presents the distribution of Ba /sup 2 +/ in groundwater from the Cambrian and Ordovician bedrock in northeastern Illinois.
