PHOENIX (AP) - Groundwater might not be able to support long-term growth in one of Arizona's major metropolitan areas.
State water regulators confirm their data shows that dozens of new subdivisions in Pinal County might not have enough water to sustain them for 100 years.
State law requires developers to prove they have at least a century's worth of water before building homes in what are known as active management areas.
The Arizona Republic had reviewed the data and said the water deficit could exceed 700 billion gallons. It also says Pinal County's potential water shortage could affect three times as many developments than the Arizona Department of Water Resources previously had disclosed.
