Groundwater is everywhere under the ground. rain comes and the water go under the ground because there is small space in the ground and the water can go in.
We need keep water clean to make water more clear to use.People can get ground water with the pomp and the pomp make water go up and people use that water.
We used water every day and we have to save ground water.
I learned that we use ground water a lot of time also when there is no ground water we can't use many ting.
