Will we fight over water in the future? Georgia-Florida-Alabama Water War…..20 years and counting.

Surface water The most usable form of water for humans on land. Most people depend on surface water to live and transport commerce, grow crops, fishing and hydroelectric power. River systems are a network of tributaries that come from a large river.

What is a Watershed? A watershed is the water that supports a given area. Any pollution that enters a watershed affects the entire area.

Groundwater Most fresh water exists as groundwater, beneath the layers of soil and rock The area underground that is saturated with water is the water table. The water that exists under the water table is call an aquifer. We use aquifers to create wells.

Water Use and Management

How much water do we use? Americans use an extreme amount of water. For recreational and residential purposes

Water Treatment Pathogens Removed from water Abiotic Hazards removed from water Bacteria Mercury Protozoa Arsenic Viruses lead Parasitic worms Humans in developed countries have ways to re-use water that is available. Water must be treated so that is potable (safe to drink).
