Water Quality Guidance for the Introduction of Non-Project Water into the Central Arizona Project
CAWCD and the United States Bureau of Reclamation are pleased to announce the release of “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, which requires the establishment of “uniform water quality standards.”
