G. Padmanabhan, NDSU professor of civil engineering, has written “Chemical Characteristics and Acid Drainage Assessment of Mine Tailings from Akara Gold Mine in Thailand,” which will appear in the Environmental Earth Sciences journal.

Acid mine drainage is an environmental concern in the mining industry. Padmanabhan's article addresses the geochemical characterization and the assessment of acid formation potential of the mine tailings generated by Akara Gold Mine, the biggest gold mine in Thailand. This research project is part of a comprehensive study to improve and better manage pollution from mining in Thailand.

Padmanabhan previously has written another article on waste rocks. He worked with Chulalak Changul, Chakkaphan Suthirat and Chantra Tongcumpou to compile the information for both articles.

Padmanabhan also has been invited to teach a course in the environmental and hazardous waste management program at Chulalongkorn University's National Center of Excellence for Environmental and Hazardous Waste Management in Bangkok, Thailand. This is the third time he has taught the course.
