Abstract
The physicochemical analysis of groundwater quality in Owerri Municipal council, Imo state, Nigeria was carried out. Fifteen water samples were randomly selected from the five villages that make up Owerri municipal council were anlayzed for physicochemical parameters using standard methods. The results from the study area showed that the temperature ranged between 26.5-28.0oC; рH ranged between 4.80-5.32. Electrical conductivity ranged between 77-166 µЅ/cm. The total dissolved solids were between 35.4-168.4mg/l; total suspended solids ranged between 4-5mg/l and alkalinity ranged between 6-10mg/l. The chloride ranged between 18.7-37.2mg/l which depicts corrosive properties of the water. The total hardness ranged between 6.0-44.4mg/l indicating soft water. Calcium hardness ranged between 3.7-38.8mg/l and magnesium hardness ranged between 2.3-5.6mg/l. Phosphate ranged between 0.18-0.40mg/l; Nitrate 18.5-114.1mg/l and Sulphate ranged between 16.1-32.7mg/l. The metallic ions like iron, lead, copper, manganese and zinc are in traces of between (0.1432-0.2166), (<0.0001-0.0711), (0.3678-1.1006), (0.01018-0.1755), (0.5716-1.3179) respectively. There is no trace of arsenic concentration. The results of the analysis carried out were compared to the World Health Organization and was found unfit for human consumption. MATLAB and ANN models were introduced using the results to ascertain the behaviour of the pollutants.
This is to protect the groundwater agricultural activities which are aimed at reducing soil acidity are recommended. This will help in increasing the pH and in reducing the corrosive nature of the groundwater. It is essential to measure and monitor the levels of nitrate pollution due to environmental and other anthropogenic imparts on periodic basis.
