Chemicals, mainly acids that are used for extraction of copper may seep into the soil nd reach the groundwater which leads to groundwater contamination. In this project the use of Time Domain Reflectometery (TDR) was assessed to analyze the impact of acids on subsurface soil at a copper mining facility. The basic method is the electrical conductivity of soil and its relation with the electrical potential along with dielectric constant. Since each material has its own specific dielectric constant, the presence of different chemicals in subsurface soil can be examined by the change in the electrical conductivity of soil. Aynak Copper mining facility in Afghanistan is considered as a case study for this research study. The parameters for experiment were as proposed in the guidelines of environmental assessment report for Aynak mine. This research project was able to attain successful results pertaining to the use of TDR as a sensor to examine the presence of sulfuric acid and copper sulfate in soil. To provide sustainable use of the sensor, different types of heat shrink tubes made of polyolefin and PVC were used to cover the TDR so that it is not affected by the impact of chemicals along with assurance that the results are not altered. For better economy of this system, the TDR sensor was made manually through copper wires covered with heat shrinking tubes. The system was able to analyze the presence of acid and show the location of leakage, and it acted as a layer over the ground which will provide more precision and accuracy. 2015-09-17 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1433862714 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1433862714 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
