  2. increase in the water table.

  3. decrease in the toxicity of groundwater.

  4. decrease in the salinity of groundwater.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ground water mining is the removal, or withdraw, of water from the natural source. Ground water is contained in specific rock units called aquifers.

Ground water mining in the coastal areas is very harmful because when the water is drawn sea water reverses its flow towards the water that is being used and causes an increase in salinity.
