H.O Nwankwoala is a lecturer in the Department of Geology, University of Port Harcourt, Nigeria. He obtained B.Sc in Geology from University of Port Harcourt and an M.Phil in Environmental Management (Environmental Geosciences option) from the Rivers State University of Science and Technology, Port Harcourt and Ph.D in Applied Hydrogeology from the University of Port Harcourt, Nigeria. He has carried out several research projects and consultancy work in the areas of Hydrogeology, and has been a Consultant Geoscientist to a number of Geoscientific/Environmental Companies/firms. He has also taken part in and coordinated a number of Environmental Impact Assessment (EIA) and groundwater potability studies. He has also served in many capacities in the academia within Nigeria and provided expertise internationally, working for United Nations Educational, Scientific and Cultural Organization (UNESCO) as Nigerian Lead Groundwater Expert in the Transboundary Water Assessment Programme (TWAP) for West and Central African countries. He is a prolific researcher and widely published in both local and international high impact factor indexed journals. He is an active member of many professional societies which include the International Association of Hydrogeologists (IAH), the Nigerian Mining and Geosciences Society (NMGS), the Nigerian Association of Petroleum Explorationists (NAPE), and the International Association of Hydrological Sciences (IAHS), amongst others.
Research Interest: His research interests are broad-based and have ranged widely over the hydrogeological spectrum, (including but not limited to environmental geochemistry, contaminant hydrogeology, biogeochemistry, geo-microbiology, environmental geo-techniques, Environmental Impact Assessment (EIA), waste management, water resources planning/management and sustainability, and environmental hydrogeology with special emphasis to hydro-geochemistry, groundwater/geochemical modelling and pollution studies, and medical geology.
