Remedies for soil and groundwater pollution: An overview
Most urban cities are experiencing population growth and increased industrial activities. This has brought most urban soil and groundwater environments under stress. There are reports of soil and groundwater pollution through landfills, gas and oil pipelines, industrial spills and leakages from underground storage tanks (USTs). Pollutants range from heavy metals to volatile organic compounds (VOCs), light non-aqueous phase liquids (LNAPL) (floaters) and dense non-aqueous phase liquids (DNAPL) (sinkers).
