  5. Blending • In 2006 Tucson was proposed a Blending plan to conserver water. • The plan is to blend groundwater with recharged Colorado River water. • The water will be mixed at a Clearwater Facility in Avra Valley. • If the plan is accepted by Arizona residents the mineral level will be set at no more than 450 mg/L , and more facilities will be built in Tucson to reduce the mineral content further. • With a possibility of raising it to 600 mg/L or even going lower than 450 mg/L

  6. The Future • With the increasing population in Pima and Maricopa county the need for sufficient fresh water becomes a topic of major concern. • The Blending Program is aimed to provide water till at least 2050.
