6. Subsidence
Answer Sinking of the earth's surface
,7. Active management area (AMA)
Answer Areas that were relying too heavily on groundwater and are now subject to heavy restrictions on
groundwater use
8. Assured Water Supply certificate
Answer Assures that developments within an AMA will have enough water for at least the next 100 years
9. Adequate Water Supply certificate
Answer Assures that developments outside of an AMA will have enough water for at least the next 100 years
10. Irrigation grandfathered right
Answer Granted to lands that were irrigated with groundwater between 1975 and 1980; can't be sold separately
from the land to which it's attached
11. Type 1 right
Answer Granted to lands that used to be irrigated (as farmland, for example) but have since been converted to another
use (e.g., building a subdivision)
12. Type 2 right
Answer Granted to lands that have never been irrigated; may not be used for irrigation
13. Irrigation non-expansion areas (INAs)
,Answer Areas where groundwater depletion is not as extreme as in AMAs, but is severe enough to require
regulation
14. Central Arizona Project (CAP)
Answer A 336-mile canal with tunnels, pipelines, pumping plants, and aque- ducts that brings 1.5 million acre-feet of
Colorado River water annually to central and southern Arizona
15. Central Groundwater Replenishment District (CAGRD)
Answer Arizona's groundwater replen- ishment authority; monitors the system to demonstrate an assured water supply in
accordance with the assured water supply rules
16. Grandfathered rights
Answer Rights to use wells that are derived from previous water usage; there are three kinds of these for well usage in
Arizona
17. Transfer of well rights
Answer Most of these rights are transferred when the attached land is sold; the Arizona Department of Water Resources
(ADWR) must be notified when this happens
18. Effluent
Answer Reclaimed from treated wastewater, this is one of the four kinds of water supply available in Arizona.
, 19. Colorado River water
Answer This water is so important that it's federally regulated. Arizona gets to use 2.8 million acre-feet of it per year.
Around 40% of the state's water comes from there to.
20. Other surface water
Answer This water comes from lakes, streams, and other rivers. It's the state's major renewable water source.
