Determination of groundwater recharge rate using multiple tracers
Abstract
Ground water rate is a critical hydrological parameter for understanding groundwater contamination and for groundwater assessment and management. The objective of this study is to determine groundwater recharge rate and transport mechanisms in the unsaturated zone using long-term natural and applied tracers in a semiarid region, Saskatchewan, Canada. Tritium, applied Cl, natural NO3, and SO4 in soil profile were analyzed. From the peak locations of these tracers, ground water recharge rate was determined from the profile distribution of these tracers. Uncertainty associated with these recharge rate estimated was also analyzed.
