Helen M. K. Essandoh is a senior lecturer in the Environmental Quality Engineering section of the Department of Civil Engineering, Kwame Nkrumah University of Science and Technology. She holds a BSc degree in Civil Engineering an MSc in Water Supply and Environmental Sanitation and a PhD in the area of wastewater treatment. Her PhD research was on the removal of conventional wastewater contaminants and endocrine disruptors by soil aquifer treatment. Her main areas of teaching at the undergraduate level are environmental quality engineering and engineering ethics. She also teaches post graduate courses in wastewater management and environmental impact assessment. 

The focus of her research is wastewater treatment although she also undertakes research in water quality and solid waste management. Areas of research in wastewater treatment include the treatment of domestic and industrial wastewater by soil aquifer treatment, constructed wetlands, vermitechnology and anaerobic digestion. Groundwater quality especially in areas with high density of onsite sanitation facilities is also of interest.

Besides being the safeguards officer for TRECK, Helen functions as an industry liaison officer and coordinates postgraduate internships for students pursuing programmes in water and environmental sanitation within the Department of Civil Engineering, as well as coordinates post graduate programmes within the KNUST Engineering Education Project (KEEP) of the College of Engineering.
