• Isotopic techniques can identify the source of contamination and yield information on process such as redox or chemical evolution, mixing and migration. • The chemical composition of relevant end members (groundwaters, produced waters, and fracturing fluids) are needed to make best diagnostic use of isotope or other geochemical techniques. 3

Emission fluorescence graphs for five groundwater tracing dyes in the activated carbon sampler eluent used by the Ozark Underground Laboratory. The dyes are pyranine (Py), fluorescein (Fl), eosine (Eos), rhodamine WT (RWT), and sulforhodamine B (SRB). All analysis was done using a synchronous scan protocol with a bandwidth separation of 17 nano- meters (nm), an excitation …

Groundwater tracing with artificial tracers involves adding a label to the groundwater that can be identified if that same water is sampled at a different location. Tracing involves making almost no assumptions about an aquifer's hydraulic properties; the principal assumption made is that the tracer can be identified when it is recovered.

Qualitative dye tracing with fluorescein dye and passive dye detectors, consisting of activated coconut charcoal identified point to point connection between representative sinkholes, sinking streams, and karst windows and the city springs and wells. Qualitative tracing confirmed the presence of infiltrated surface water from a perennial stream, Valley Creek, in water from city …

Groundwater dye tracing is a powerful hy-drogeologic tool for resolving these ambiguities when used in well-planned experiments. Like any powerful tool, it also has its pitfalls, however, and when misapplied can cause considerable problems. These protocols standardize the methods used by the Kentucky Geological Survey for groundwater

able techniques to determine interactions between ground-water and surface water is broad. Depending on the study purpose, methods have to be chosen which are appropriate for the respective spatial and temporal scale. If processes or flow paths are the study focus, other methods are needed than for the quantification of regional groundwater ...
