GEOLOGY

Detailed explanation-1: -Once in the landfill, chemicals can leach into the ground water by means of precipitation and sur-face runoff. New landfills are required to have clay or synthetic liners and leachate (liquid from a landfill containing contaminants) collection sys-tems to protect ground water.

Detailed explanation-2: -Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land’s surface can move through the soil and end up in the groundwater.

Detailed explanation-3: -Once waste is deposited at the landfill, pollution can arise from the percolation of leachate to the porous ground surface. Contamination of groundwater by such leachate renders it and the associated aquifer unreliable for domestic water supply and other uses.

Detailed explanation-4: -Using the Precautionary Principle. Monitoring Quality of Groundwater through a telemetry system. Land Zoning or Marking. Via Statuary Regulations. Educating Others. 12-Mar-2021
