M. Hashim Pashtun to Present Research on Preventing Groundwater Contamination in Mining Operations

Libraries Graduate Research SeriesThe Libraries’ Graduate Research Series (GRS) continues on Wednesday, March 15, when Civil Engineering doctoral candidate in the Russ College of Engineering M. Hashim Pashtun shares his research on a Time Domain Reflectometery (TDR) sensor for the early detection of groundwater contamination in copper mining. The presentation will be at 3:30pm in the Friends of the Libraries Room (Alden Library 319).

Mining activities pose risks to the environment surrounding the facility and to the local groundwater. Pashtun’s research addresses the potential for groundwater contamination by developing a sensor that quickly identifies and locates chemical leaks in the soil. TDR cables were tested in the laboratory under a wide range of soil and geotechnical conditions, with the research showing that the durable and economically feasible TDR technology can detect copper sulfate in the soil even at concentrations lower than usually seen in commercial operations.

Early identification of chemical leaks has the potential to limit the risk of groundwater contamination and to prevent the high cost of pollution remediation for the operating facility.

The GRS serves as an opportunity for graduate students to share their research with the OHIO community and to bring to light the many resources and services at Ohio University that make such research possible. We invite you to join us for Pashtun’s presentation, which is open to the public. Light refreshments will be provided. Questions about the GRS and Pashtun’s presentation may be directed to Miriam Intrator or Barbara Fiocchi.
