This week’s big pulse of water into the long-parched Colorado River Delta will be one of the most studied water releases ever.
Rosemont Copper has met extensive government requirements to improve its mine proposal, and so it is time to accept that the mine will be built. We respect the laws, though flawed, that permit mining in a national forest in a region with limited water.
Here’s why water must be Arizona’s top public-policy debate:
All residents in Pima County are created equal and assume they are equally entitled to their water. This assumption could be jeopardized if Rosemont Mine opponents convince the Tucson City Council to oppose Community Water Company of Green Valley’s pipeline connection.
The Tanque Verde Wash, unlike most of its Tucson counterparts, still blooms with yellowing cottonwood and willow trees during autumn’s current peak.
Despite years of growing concern about drought, some good water news has emerged: The Tucson area has balanced its water pumping with recharge more than a decade ahead of schedule.
Davidson Canyon and Cienega Creek — linchpin issues for many who oppose the Rosemont Mine — aren’t in as big a danger from mine impacts as many people think, the U.S. Forest Service says.
When deciding if a development should be blocked, Arizona water regulators lack the power to consider whether groundwater pumping for the project could lower the neighboring San Pedro River.
A pipeline to allow owners of the Rosemont mine to recharge Central Arizona Project water to compensate for its groundwater pumping will start its first leg of construction next month, a private water company building the line said Tuesday.
Two bills that would help Arizona’s mining industry — and in one case numerous other industries — with environmental matters are moving through the Legislature.
