Profile

Dr. Michael Kumi is a Senior Research Scientist in the Environmental Chemistry and Sanitation Engineering Division of the Council for Scientific and Industrial Research-Water Research Institute (CSIR-WRI). He earned his Bachelor’s degree in Biological Sciences with a major in Chemistry from the University of Cape Coast in 2001, followed by a Master’s degree in Ecotechnology from Mid Sweden University Östersund, Sweden, in 2007. He obtained his PhD in Chemistry from the University of Johannesburg, South Africa. Dr. Kumi possesses extensive experience in water quality monitoring and assessment, specializing in contamination and remediation, risk assessment, and water quality modeling. His research focuses on heavy metal assessment, nutrient analysis, modeling, climate change impacts on water quality, and phytoremediation.

Dr. Kumi has contributed significantly to academia, teaching at the master's level and supervising numerous students at both bachelor's and master's levels in two Ghanaian universities. He has also served as a reviewer for various international journals such as Water Science and Technology, Environmental Monitoring and Assessment, and Applied Water Science. Additionally, he has coordinated consultancy services for governmental and non-governmental agencies, companies, communities, and private individuals, particularly in water quality assessment, phytoremediation, and ensuring water quality for aquaculture farming in Northern Ghana. In addition to his research and teaching responsibilities, he supervises technical staff.

With over 16 peer-reviewed articles published in international journals including Water and Environment, Water Resource and Protection, and Earth and Climate Change, Dr. Kumi's contributions to the field are widely recognized.

Research Interests:

• Water technology development
• Use of bone char and biochar for water treatment
• Geochemical contaminations and deterioration of groundwater quality
• Pollution and ecological studies of Ramsar sites
• Emerging contaminants in water: Sources, fate, and occurrence
• Hydrological response to climate change
• Water quality monitoring and modeling
• Optimization of water quality monitoring networks
• Ecohydrology

Current Research:

Dr. Kumi's current research focuses on water technology development, particularly the utilization of bone char and biochar for water treatment. His research encompasses physio-chemical assessments of water quality for aquaculture, wastewater, and drinking water, with a specific emphasis on trace metals and ecotechnology. Through the use of multi-tracers, computational chemistry techniques, and isotopic tracer technology, he aims to characterize sources of surface and groundwater contamination, addressing the long-term deterioration of water quality. His research methodology combines desktop studies, laboratory experiments, and fieldwork to prevent environmental water deterioration and its subsequent effects on human health, crucial for effective water resource management in the 21st century.

Ongoing research projects include:

1. Treatment of contaminated groundwater using integrated bone char and biochar.
2. Pollution and ecological studies of two Ramsar sites: Sakumo I and Sakumo II in Ghana.
3. Monthly effluents quality monitoring of a pharmaceutical facility in Accra.
4. Robot-aided chemical synthesis.
