Perchlorate in groundwater can be from synthetic or natmal sources. the latter of which include both historical application of impotted nitrate fertilizers fi·om the Atacama Desert of Chile and atmospheric perchlorate. The objective of this study was to evaluate the use of isotopic data to distinguish somces of perchlorate in groundwater in a specific region of the Rialto-Colton and Chino. CA groundwater subbasins. Perchlorate extrac ted from wells in tlus region was analyzed for chlorine and oxygen stable isotope ratios and radioactive chlorine-36 isotopic abundance. along w ith other geochenucal. isotopic. and hydrogeologic data. The stable isotope and chlOI~ne-36 data provided relatively unambiguous discrinunation of synthetic and Atacama perchlorate sources in most wells having relatively high concentt·ations. providing regional perspective on anthl'Opogenic perchlorate contamination in the Rialto-Colton and Cluno subbasins. Where indigenous natmal perchlorate was indicated as a substantial component. total perchlorate concentt·ations were low and concentrations of anthropogenic components were near backgrotmd levels.

“…In areas with significant rainfall it is readily leached out of surface strata into ground and surface waters (Urbansky and Brown, 2003). In arid regions it accumulates at the surface and considerable concentrations have been detected (Rao et al, 2007;Jackson et al, 2010). If other areas are equally prolific sources of ClO 4 À , but lack the concentrating mechanism, this would imply widespread, multimedia dispersal of ClO 4 À across the environment.…”

Perchlorate (ClO4−) has been detected on Mars, but its production and distribution are unclear. Mechanisms requiring atmospheric chlorine are insufficient for measured concentrations. We conducted studies under Mars conditions using halite (NaCl) alone, soil simulants consisting of silica (SiO2), Fe2O3, Al2O3, and TiO2. After 170 h irradiation, samples analyzed by ion chromatography (IC) showed ClO4− and ClO3− present in all samples. When SiO2 was added, yield increased from 2 to 42 nmol and 0.4 to 2.6 nmol, respectively. We attribute this to SiO2 and metal oxides acting as photocatalysts, generating O2− radicals from O2 which react with chloride. Results show ClO4− and ClO3− can be produced photochemically on Cl minerals without atmospheric chlorine or aqueous conditions, and explain high concentration of ClO4− and ClO4−/Cl− ratios detected by Phoenix. They provide evidence that its distribution on Mars is dictated by distribution of chlorine and provide insight into the oxidizing nature of the soil and its potential effects on organics.
