PROFILE

Dr. Franklin Obiri-Nyarko is a Research Scientist in the Groundwater Division of the Council for Scientific and Industrial Research-Water Research Institute (CSIR-WRI). He holds a Bachelor’s degree in Agriculture (Soil Science) from the University of Ghana, a Master’s degree in Geosciences (Environmental Geology and Geohazards) from the University of Oslo, and a Ph.D. in Earth Science from the AGH University of Science and Technology.  Dr. Obiri-Nyarko has a wealth of experience in contaminant hydrogeology. He has published a number of scientific articles and also reviewed manuscripts for journals and international conferences, such as Water and Environment Journal; Separation Science and Technology; Chemosphere; Geology, Geophysics, and Environment; Environmental Engineering Science; Environmental Geochemistry and Health; and International Conference on Water Resource and Environment. He has participated in a number of international conferences, workshops, and seminars, and was a session co-chair for the first International Conference on In-Situ Remediation in London, UK (2014).  He is currently on the Editorial Board of Peertechz Journal of Environmental Science and Toxicology.

Research interest

Dr. Obiri-Nyarko’s research interests include: laboratory and field studies of the transport and fate of pollutants and natural attenuation processes; numerical modelling of groundwater flow, contaminant transport, and biogeochemical processes in aquifers; groundwater and waste water treatment using natural and synthetic adsorbents; and the design of stand-alone drinking water treatment technologies and engineered barriers for the remediation of soil and groundwater contaminated by landfill leachates, acid mine drainage, agricultural chemicals, and petroleum hydrocarbons.
