GEOLOCATION AND STUDY OF HOUSEHOLD WELL WATER IN RELATION TO CONTAMINANTS AS HEALTH MAPPING TOOL IN KUMBA, SOUTH WEST REGION, CAMEROON

Abstract

The poor level of public water supply gives the water Wells an important place in the life of the population of Kumba. Unfortunately, its quality is a major challenge. With the present population growth rate estimated at about 4% annually, more inhabitants turn to these sources of water. The objective of this study is to geolocate the water wells and their contaminants sources at Anglican Quarter, Kumba I Subdivision, and also to realize the chemical analyses of the water collected. By so doing, helping the sanitation authorities to realize the health map of Anglican and to show the importance of GIS in health. The coordinates of the wells and the contaminants sources were taken with a GPS receiver and their depths, through a plumb bulb and a tape. The chemical analyses of the sample water collected were done in a laboratory. The tape was used to obtain the proximity of wells and the contaminants falling between 0 to 15m and above. The result shows that 3.3% of wells have good pH according to WHO, 16,7% in nitrate, and concerning electrical conductivity, no well met the WHO norms when 3,3% in chloride. This result can directly help the health authorities to identify the types of water diseases located in the quarters studied
