This research presents a review on water resources in Delta state,south­ern part of Nigeria,with emphasis on hydrogeochemical and microbial assessment.It evaluates factors responsible for water contamination,and their resulting health challenges within the study area.To achieve the ob­jective of this study,related articles were downloaded from Google,pub­lished article on influence of hydrogeochemical and microbial activities on water resources.These articles were thoroughly studied.Findings from this study,suggested that groundwater was more studied than surface wa­ter.We also observed that groundwater within the riverine communities is much more prone to pollution when compared to groundwater in an up­land area.Results from various authors suggested that,larger percentage of groundwater showed presence of coliform.Further findings suggested that geochemical processes such as rock water interaction,seawater in­trusion and precipitation influences groundwater quality within the study area especially within Sombreiro-Warri Deltaic Plain Deposit. 展开更多
