||Basement groundwaters in the south and southwest have low conductivity (average 375 uS/cm) and an average pH of 7.2 (although this can vary between 5.6 and 8.8). Chloride and sulphate concentrations are less than 20 mg/l. In the Kayes and Adrar des Iforas regions, groundwaters are more mineralised, with conductivities around 1000 S/cm and 300-8000 S/cm, respectively.
