The Water Resources of Earth
Over 70% of our Earth's surface is covered by water ( we should really call our planet "Ocean" instead of "Earth"). Although water is seemingly abundant, the real issue is the amount of fresh water available.
· 97.5% of all water on Earth is salt water, leaving only 2.5% as fresh water
· Nearly 70% of that fresh water is frozen in the icecaps of Antarctica and Greenland; most of the remainder is present as soil moisture, or lies in deep underground aquifers as groundwater not accessible to human use.
· < 1% of the world's fresh water (~0.007% of all water on earth) is accessible for direct human uses. This is the water found in lakes, rivers, reservoirs and those underground sources that are shallow enough to be tapped at an affordable cost. Only this amount is regularly renewed by rain and snowfall, and is therefore available on a sustainable basis.

Ingredients that water environments need to be

cultural eutrophication (The Tennessee

Natural Impacts
Cultural (Human) Impacts
We
want a balanced level of SAVs – submerged aquatic vegetation
POINT v. NONPOINT Issues
DO
and BOD link – Water needs oxygen
(Not water, organisms in water)
O2 gas dissolving into
water=Dissolved Oxygen
A Good Range – (Control) 8-14 or 7-11 milligrams of Dissolved Oxygen per Liter à à 11mg DO/L
HOW DOES RECOVERY OCCUR OF CULTURAL
DAMAGE OF WATER RESOURCES?
Aquifers and Water Quality
Non Pelagic but Neritic Water Resources – Marine (Saltwater),
Estuaries, Freshwater, Watersheds, Aquifers, Rivers, Lakes, Wetlands, Streams,
Oceans.
HOW CAN WATER BE IMPROVED?
· The CWA and NPDES
· Groundwater diversion and management
· Primary, Secondary and Tertiary(?) BMPs to control TMDL
· Leach Fields
· Wells!!
· Organic “Pottys”
