The study involved the environmental impacts of human activities on the geo-environment within Warri-Effurun, which is a sedimentary terrain, underlain by the Sombreiro Warri Deltaic plain. Surface and ground water samples were collected (including rain water samples) at the studied area, and were analyzed to determine the physico-chemical and bacteriological characteristics with a view to ascertaining the level of contamination and suitability for human consumption. The result of the surface and ground water showed that there are increased values (relative to control) in the area, but more pronounced in highly populated environment and relatively high in the industrial area, and also evident as compared with the established regulatory criteria (WHO and FMEnv). The coliform count for the bacteriological analysis indicates strongly that some of the boreholes, wells and river samples were contaminated by faecal bacterial from human and possibly animals. Therefore, it is obvious that anthropogenic activities and population distribution are the influencing factors of the hydrogeochemistry which rendered some of the water samples unfit for consumption unless otherwise treated.
