Applicability of Stable Isotope Fractionation Analysis for ...

In recent years the analysis of stable isotope fractionation has increasingly been used for characterizing and quantifying biodegradation of contaminants in aquifers. The correlation of carbon and hydrogen isotope signatures of benzene in a BTEXcontaminated aquifer located in the area of a former hydrogenation plant gave indications that ...

Radiocarbon dating groundwater AMS lab Beta Analytic

Radiocarbon dating of groundwater can give indications as to when the water was taken out of contact with the atmosphere, when it went underground. Radiocarbon dating of groundwater is used in combination with the primary measurements of classical hydrological and chemical analyses.

Groundwater recharge/discharge in semiarid regions ...

However, evaporative fractionation in the flow path's final reach in the southeast reenriches the isotopic composition and suggests evaporative loss of groundwater as the plausible discharge mechanism. Chloride concentration increases down the gradient from the recharge area and reaches its peak in the discharge zones indicating: lack of recharge from direct infiltration down the gradient ...

Isotopic fractionation by diffusion in groundwater ...

Analyses in transport regimes characterized by thin aquifers, thick aquitards and fast flow parallel to the bedding plane, wherein the effects of diffusion have been well established and occur prominently, delimit the possible extent of isotopic fractionation by diffusion in groundwater.
