सारांश	Soil remediation encompasses a suite of technologies and strategies to treat contaminated soil at sites with elevated levels of organic compounds, heavy metals, radionuclides, or other hazardous substances. Systematized by the US EPA in the 1980s following industrial accidents and legacy contamination discoveries, soil remediation methods range from in situ (biological, chemical, thermal) to ex situ (excavation, treatment, off-site disposal) approaches. The selection process integrates site characterization, contaminant bioavailability, regulatory risk thresholds, and cost-benefit analysis.	Groundwater contamination modeling is a quantitative approach to predict the migration of dissolved and suspended contaminants (chemical spills, landfill leachate, petroleum, radionuclides) through subsurface aquifers and toward receptors (drinking water wells, surface water bodies, ecosystems). Developed systematically in the 1980s–1990s by the USGS and hydrogeologists, these models couple flow equations (Darcy's law) with advection-dispersion transport and geochemical reactions to forecast contaminant arrival times and plume extent.
