Answer

Brief Explanations:

  • Option a: Pollutants from surface water can seep through permeable soil/rock layers down to aquifers, contaminating groundwater.
  • Option b: Some industrial operations may directly discharge waste into aquifers (e.g., via injection wells or improper dumping into open aquifer access points), causing pollution.
  • Option c: Garbage dumps can leach contaminants as rainwater filters through refuse, which then infiltrates the water table and pollutes groundwater. All three mechanisms are valid ways groundwater becomes polluted.

Answer:

d. All of the above
