National Groundwater Awareness Week starts today. Or tomorrow, depending which page on the National Ground Water Association web site you want read.
But regardless, NGWA points out that 90% of all fresh water in the world is groundwater. About 12 million households rely on wells for their water, as do many communities for all or part of their water.
NGWA has compiled a list of resource links for each state, including Arizona.
The Association of American State Geologists (of which AZGS is a member, is co-sponsoring the Week).
