- the Excessive pumping of groundwater from aquifers use results in subsidence, or sinking of the Earth’s surface. Groundwater can be effected by human activity when pollutants seep though porous material and contaminates the groundwater resources.

- Surface water in a watershed flows into small streams and small gullys which flow into larger bodies of water like rivers, lakes and oceans.

- human activity that contaminates the aquifers is usually put into two different types of pollution,point source and non-point source.
