Cardno senior geologist presenting at annual mine drainage symposium

Geology and hydrogeology practice leader Ron Mullennex, CPG, CGWP, will present Comparative Performance of Different Alkaline Addition Rates in Kinetic Test Results at the West Virginia Mine Drainage Task Force Symposium in Morgantown, West Virginia, on Wednesday, March 30. Hydrogeologist Ankan Basu, CPG, co-authored the presentation.

Coal processing commonly results in concentration of pyritic sulfur into the reject fraction or refuse material from the operation. Ron will discuss the results of a kinetic testing program that examined how alkaline (limestone) addition at different rates may affect the initiation and degree of acid generation from relatively high-sulfur-content refuse material. A common regulatory requirement for disposal of such material requires an alkaline addition at a rate based on the stoichiometrically calculated acid-base balance, i.e. the quantities of chemical elements or compounds involved in the chemical reaction.

The West Virginia Mine Drainage Task Force was formed in 1978 to investigate acid mine drainage problems associated with surface mining in the state. The Task Force’s mission is to stay current on new developments in mine drainage research and treatment and control practices. The annual symposium is held for members to present this information to the industry, regulatory authorities, and academia.

Ron, also a Senior Principal, has more than 40 years of experience in resource and mining geology, hydrogeology, environmental issues, and engineering and geomorphic applications. He is certified or licensed as a geologist in seven states, including West Virginia, and is a member of the Visiting Committee of the Department of Geology and Geography at West Virginia University.
