*Physicochemical properties of underground water in Jalingo Metropolis during rainy season.*

All sites in the study area during the dry season were within the WHO permissible limit of 6.5–8.5 except sites SB1 (8.6) SD1 (8.8) SD2 (8.9) SD3 (8.9), MD, (8.6) KS1 (8.9) band KS2 (8.6) these high values show alkalinity and it could be due to high concentration of basic cations e.g. magnesium, calcium, potassium etc. in the sampled sites.

All sites in the rainy season were within the WHO permissible limit of 6.5–8.5.

### **3.3 Electrical conductivity**

Electrical conductivity is the ability of any medium, water in this case, to carry an electric current. The presence of dissolved solids such as calcium, chloride, and magnesium in water samples carries the electric current through water. Conductivity values obtained in this study showed that all the sample sites contained
