• Arsenic in Arizona Ground Water -- Source and Transport Characteristics

      Following on the U.S. Environmental Protection Agency's "Arsenic Rule" decision to require public water systems to lower the allowable arsenic content in drinking water from 50 parts per billion (ppb) to 10 ppb by January 23, 2006, private well owners across the state have realized the importance of testing their own water supply for arsenic. Under Arizona law, it is the sole responsibility of the private well owner to determine the quality (potability) of their private well water. This article discusses the geologic prevelance of arsenic across the state, and options available to the well owner to address this water quality concern. Expected to be the first in a 3-part series on ground water quality issues common in Arizona.

      Limited information is available to the County Extension offices to address common concerns of water supply in rural Arizona. In addition, in the more metropolitan areas of the state, little is understood about water resources. This project is proposed to provide a ten to twelve page primer on water resources on a county-by-county basis, beginning with Yavapai County.
