Determining Timescales for Groundwater Flow and Solute Transport,sidence times in association with groundwater contamination studies can enable historic release rates of contaminants and contaminant transport rates to be determined. Where input rates are known, measurements of groundwater contaminant concentrations, together with groundwater dating, can sometimes

Noble Gas Radioisotopes: 37Ar, 85Kr, 39Ar, 81Kr,are rather complicated. Nevertheless, very valuable results have been achieved in a number of groundwater studies. Since the number of dating tools is quite limited in hydrogeology, any additional information is welcome even if the analytical effort is considerably higher than for some other tracers
