| Long description: |
The Cuise Sands Aquifer, located in a small agricultural catchment where agricultural practices are well documented, over a 5 year period showed significant disparities for major element concentrations, Sr concentrations, isotopic composition and pH values, depending on the groundwater sampling location. The use of strontium isotopes in combinaton with Mg/Sr and Ca/Sr ratios of groundwater was used to trace fertilizer contributions, which significantly modify the natural Sr isotopic signature of groundwater. The geochemical signature of groundwater also revealed the partial isolation of groundwater bodies in the catchment. Thus, the Sr isotopes coupled with Mg/Sr and Ca/Sr ratios have been applied with success to trace water pathways and recharge and assess the functionality of the system.
