≫ Groundwater Pollution
Generally, groundwater is good for drinking. Groundwater that is polluted is less visible and difficult to clean up than lakes and rivers. Most often groundwater pollution results from the disposal of wastes improperly including household and industrial chemicals, wastewater from mines, leaking underground oil storage, oil field brine pits, garbage landfills, and sewage systems.
Prevention of groundwater pollution can be done by:

  • storing rainwater
  • watertight materials
  • collecting leachate with drains
