Abstract

Occurrence of uranium isotopes in groundwater provides a tracer technology for quality, sources, and recharge conditions. Groundwater samples collected from different aquifer types (sand dune, Quaternary clastics, ophiolite, carbonates and sabkha) in the UAE were analyzed for ²³⁸U and ²³⁵U. In addition to uranium isotopes, monitoring indicators also cover groundwater pH, temperature and TDS. The concentration of uranium isotopes (²³⁸U + ²³⁵U) range from 4 to 69,745 ng/L. The distribution of the isotopes in the groundwater of the UAE can be linked to aquifer lithological variability, distance from recharge front and seawater intrusion. In general, about 3% of the groundwater analyzed have uranium concentration above the WHO permissible limit for drinking water.
