Quiz which condition could lead to drawdown below the level of existing wells?
irinina [24]

<u>Answer:</u>

  • During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.
  • But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.
  • To prevent this, the groundwater should be recharged and over drawing should be avoided.
