Ground Characterization of Abandoned Open Pits Liable to Illegal Industrial Waste Dumping: A Case Study of Thailand’s Chachoengsao Province
Abstract:
This research has investigated the geotechnical properties of abandoned open pits in Thailand’s eastern province of Chachoengsao that could become targets for illegal industrial waste dumping. Out of a total of 11 districts, this research focuses on two districts, i.e. Plaengyao and Panom Sarakarm, due to the proximity to industrial estates and abundance of open pits. The findings reveal a very low permeability rate of Plaengyao’s surface soil, indicating that no open pits should be used as dumping sites as contaminants are captured by and deposited in the surface soil. Clay liner and surface drainage are needed to be considered for Landfills in Plaengyao district. In contrast, the surface soil of Panom Sarakarm district is of high permeability and thereby renders the utilization of open pits environmentally harmful since the dissolved contaminants can leach through the ground and pollute groundwater.
