Abstract: In many parts of the world, including United States of America, health problems and diseases have often been caused by discharging untreated or inadequately treated wastewater into the environment. This study employed GIS (Geographic Information System) techniques at the data collection, analysis and presentation stages to investigate the health impacts of domestic wastewater disposal in the study area. The research discovered that about eighty six percent (86%) of the sampled households have negative health impacts on land surfaces, waterbodies and human beings in the study area. There are significant average negative impacts of domestic wastewater disposal on all the eight Areas and two regions of the study area. The authors recommend; formal and informal education, new and efficient Government Agency, new legislation, and a GIS inventory database for domestic wastewater disposal for the study area.
