Groundwater depletion is a serious threat to the environment the majority of our bodies and the earth is made up of water we may see the beautiful, flowing surface waters that make up the oceans, lakes and rivers, but this water is not always safe for consumption and is much more difficult to filter than groundwater. Groundwater can be polluted by landfills, septic tanks, leaky underground gas tanks, and from overuse of fertilizers and pesticides if groundwater becomes polluted, it will no longer be safe to drink.
