Often, the task can be much more immediate, especially when groundwater contamination is a concern.

Tucson Water is the municipal water supplier for the City of Tucson and much of the surrounding area. The nearly 30 billion gallons of drinking water delivered by the utility to its 722,000 customers each year is pumped from area aquifers, although about 90 percent of that current volume is native groundwater blended with recharged Colorado River water.
