Five parameters (Nitrate, Magnesium, Copper, Calcium and Iron) were used to test the quality of water
samples collected from twenty two commercial boreholes along the River Yedzeram which is the main river
that runs across the Mubi town, using the standard examination of water and waste water of the World
Health Organization to determine the water quality of the boreholes. The study revealed that only eight out
of the twenty two boreholes are of good quality, while the others are either of bad quality or not portable.
ArcGIS 9.3 was used to map, create database and analyze the laboratory results through the use of SQL
queries. It was recommended that the government should provide portable water, establish water quality
control board and make use of GIS techniques for creation of database and analysis of water quality for easy
monitoring and control.
