Groundwater Quality Mapping In Ikot Abasi Using Geographic Information System (GIS) (Published)
In this work, the GIS Software Quantum 1.7.0 was used to analyse and create groundwater contoured maps for Ikot Abasi. Five groundwater samples were collected and analysed for some physical parameters (pH, temperature, turbidity, conductivity, total dissolved solids) and trace metals (aluminum, zinc, manganese, chlorine, copper). The physical properties were measured directly using HQ40D multi-parameter, while the trace metals were determined using atomic emission spectroscopy. The water parameters of concern were aluminum and manganese because they had marked departure from the WHO standard. The aluminum values in the area ranged from 0.2 mg/l to 0.4 mg/l, with an average value of 0.34 mg/l which is above the WHO limit of 0.2 mg/l. The manganese values in the area ranged from 2.13 mg/l to 2.18 mg/l, with an average value of 2.16 mg/l which is above the WHO limit of 0.1 mg/l. Treatment measures should be considered to reduce the concentration of these metals.
