ESTIMATING CHLORIDE CONCENTRATION IN SURFACE WATER AND GROUNDWATER DUE TO DEICING SALT APPLICATION

摘要: The thesis presents a simple tool that quantifies the increase in chloride concentration for water catchment area, based on steady-state balance. Roads are source of pollution and groundwater surrounds highway. Metals, hydrocarbon, sodium some examples. An accident where hazardous material is discharged could also lead to severe pollution. ion deicing salt good tracer. If calcium increases vicinity highway one might expect other road related pollutants present. Data processed presented as maps with GIS. At regional level increased concentrations were calculated. Variability between areas was verified by national lake monitoring programme. A distributed dynamic method used evaluate temporal spatial variation an aquifer. approach integrated spreading from infiltration unsaturated zone soil, which turn ground waterflow. simulation run 40-year period showed potential describe specific system.
