The study aims at systematic literature review on sources of water pollution, causes of water pollution, categories of water pollution and its mitigating control measures. Twenty eight (28) related articles were employed for the study. The scholar's contributions were viewed under water pollution contextual definitions, sources of water pollution consider, classification and categories of water pollution were assessed, causes of water pollution scholarly contributions were evaluated and mitigating control measures as stated by scholars were also highlighted in this studies. Additionally, twenty eight (28) journals employed for the studies uncover the statistical distributions as; control of water pollution is more popular among the scholars who constitute 36%, categories of water pollution with 25%, causes of water pollution as contributed by scholars 21%, sources of water pollution are least popular among the scholars with 18%. This shows water pollution experts globally are more concerned with its control measures rather than sources, causes and categories of water pollution. Furthermore, the articles employed for the study uncover that, articles that dwells on global perspective are more than those whose work are solely on Asian countries, Europe/US as well as African continents. This depicts that water pollution experts are distributed across the globe. The study recommends human behavior approach and techniques in controlling water pollution especially in developing world should be implemented. Solid waste from households, industries and agricultural products should be properly controlled through proper campaign with the aid of public lecture, billboards to convey messages, visual broadcasting and audio broadcasting and with the aid and support of pamphlets. Sewage from both households & industries should be properly monitored by government by enacting policies for the industrialists to treat effluents before discharging in to water bodies. This could be achieved through organizing environmentally friendly conference, workshops, seminars and it should be organize periodically so as to create avenue for sharing new ideas and methodologies interchanged by the experts
