Soil and Groundwater Contamination and Remediation Technology in Europe | SpringerLinkContaminant transport in subsurface water is the major pathway for contamination spread from contaminated sites to groundwater supplies, to remediate a contaminated site. The aim of this paper was to set up the groundwater contaminant transport model for the Wang-Tien landfill site, in southwestern Taiwan, which exhibits high contamination of soil and groundwater and therefore represents a potential threat for the adjacent Hsu-Hsian Creek. Groundwater Modeling System software, which is the most sophisticated groundwater modeling tool available today, was used to numerically model groundwater flow and contaminant transport. The simulation produced a plume of contaminated groundwater that extends 80 m in length and 20 m in depth northeastward from the landfill site. Although the results show that the concentrations of ammonium nitrogen and chlorides in most parts are low, they are 3. Generally, landfills will cause lots environmental pollution, such as smells in the air, landfill gas combustion, and wastewater leakage. Among all these, wastewater leakage affects the surrounding environment the most, especially the groundwater quality because wastewater leakage consists of high concentrations of organic compounds, heavy metal ions and toxic hazards.
We ahd discovered in some parts of the site that contaminated the ammonium nitrogen and chlorides were over the Taiwan EPA standard. Porter, G. Oostrom, B.
