This inaugural, all-digital version of the Arizona Water Resources newsletter features groundwater, the “invisible” water as characterized by WRRC Director Sharon B. Megdal in her Fall 2016 Public Policy Review column. Various perspectives and components of the large topic of groundwater are represented in an effort bring attention to its significance locally, nationally, and globally. We are pleased to present the work of guest authors as well as our own Graduate Outreach Assistant. Readers are invited to contact the editor with comments on our content and new format.
Arsenic in Groundwater Poses Ongoing Challenge
Arsenic contamination of groundwater is a problem in many areas of the world, including Arizona. Exposure to arsenic in drinking water has been linked to negative health effects including cancer. Yet in many places, populations have little choice but to continue drinking arsenic contaminated water and in some places the problem is getting worse.
Whither Critical Area and Sub-AMA Groundwater Management in Arizona?
It is well-known that Arizona has made significant progress towards reducing groundwater overdraft where groundwater depletion has historically been most severe, the designated Active Management Areas.
According to National Groundwater Association’s Facts about Global Groundwater Usage (Oct. 2016), groundwater provides almost half of all drinking water worldwide and supports 38 percent of irrigated lands globally.
