Groundwater Pollution

Water covers 71% of the Earth’s surface 97.4% is salt water located in the oceans 2.6% is fresh water found in ice caps, groundwater, and surface water Only .014% is easily available for our use from lakes/streams/usable groundwater

Groundwater: Water that has entered the ground through the process of infiltration. The amount of groundwater depends on the material at or under the Earth’s surface and the amount of precipitation

Uses of Groundwater: Irrigation for crops *Largest Use Water for Livestock Industries Public Service Mining Homes and Public Buildings *Smallest Use

What is an Aquifer? An aquifer is an underground storage of water. Sits above the bedrock (which cannot be infiltrated). Aquifers can be depleted with overuse.

Groundwater Pollution 25% of our drinking water comes from a groundwater source= WELLS Pollution Sources: 1. Sewage 2. Industrial Waste 3. Landfills 4. Agricultural Chemicals
