Draft Water Quality Guidance Document Released for Public Comment

CAWCD and the United States Bureau of Reclamation are pleased to announce the release of the draft document “Water Quality Guidance for the Introduction of Non-Project Water Into the Central Arizona Project.”  This guidance document includes extensive numeric standards as well as implementation details for parties proposing to use the CAP system to transport non-Colorado River water supplies.  The document helps fulfill Article 12.1 of the CAP System Use Agreement between Reclamation and CAWCD (here), which requires the establishment of “uniform water quality standards.”
