Environmental
Indicator #6:
Water
Overpumping of groundwater is causing water tables to decline in key agricultural regions in Asia, North Africa, the Middle East, and the United States.  The quality of groundwater is also deteriorating as a result of runoff of fertilizers and pesticides, petro-chemicals that leak out of storage tanks, chlorinated solvents and heavy metals discarded by industries, and radioactive wastes from nuclear facilities.
