Oxidation–reduction sequences in ground water flow systems
Abstract
Hydrogeologists and ground water geochemists have observed a decline in the measured (platinum electrode) potential, E H, of ground water as it migrates from upland recharge areas to lowland discharge areas under confined conditions. Such variations in E H and variations in concentrations of elements with variable oxidation states (e.g., oxygen, nitrogen, iron, manganese, sulfur, and carbon) can be accounted for by a sequence of oxidation–reduction reactions occurring in the flow systems, the sequence being based on thermodynamic principles as outlined by Stumm and the microbial catalysis of such reactions. This sequence of reactions results in the identification of three redox zones in ground water flow systems: (1) oxygen–nitrate, (2) iron–manganese, and (3) sulfide. The mobility and concentration of most transition metal and nonmetal ions vary according to zone—a matter of considerable significance in exploration geochemistry and in ground water pollution studies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
