Arsenic in Arizona's Water Supply

To reduce the risk of cancer from this chronic exposure to arsenic, the EPA changed the allowable limit for drinking water from 50 ppb to 10 ppb in January of 2006. This is projected to reduce the risk of cancer and other illnesses from arsenic by around 80%. The exact benefit cannot be defined because other sources of arsenic such as food or air are contributors to the health risk.  View document.

2012-04-16 The Case for a Water Management District

What are water districts? They are regional governmental authorities established by state legislation. Each district has its own set of rules – as agreed upon locally, not in Phoenix. Its governing board would be democratically determined probably by local election or appointing the county Board of Supervisors as the district board. State legislation may be written in a way that the district could only be established by an election of the district's voters. View document.

2012-04-16 Safe Yield

What is SAFE YIELD?  Why is it important? How do we achieve it? In Arizona, safe yield refers to a long-term balance between the water that is naturally and artificially recharged to an aquifer and the groundwater that is pumped out. When more water is removed than is recharged, the aquifer is described as being out of safe yield. When the water level in the aquifer then drops, we are said to be mining groundwater. View a pdf.

2012-04-16 The Importance of Conservation

Where we use water is a key to conservation. Water used outside the home, most typically for watering vegetation, is lost to the atmosphere. Water used in the home can be returned to the aquifer. This is performed efficiently in municipalities that have central collection, treatment and recharge facilities. It is done less efficiently in communities that use septic tanks with leach fields. While conservation of all uses is valuable, the greatest benefits will come from outdoor uses. View document.
