California Integrated Water Quality System Project (CIWQS) PET Tool / CIWQS Data Format

PET Tool

  • Introduction
    The PET Tool is a Microsoft Excel file that allows you to configure your data into a format that CIWQS will understand and interpret correctly, which is the CIWQS Data Format, or CDF. You can open the PET Tool in Excel, configure it on the basis of your permit requirements, and then use the configured file as a template for entering monitoring data on a monthly basis.
    Important Note:     The Tools require that macros be enabled.

    • CEDEN Compatible PET Tool - use this PET Tool to record fields required by CEDEN. By submitting surface water quality data consistent with CEDEN, and that includes the data elements required for assessment, the data can be assessed for the Integrated Report [303(d) List of Impaired Waters and 305(b) Condition Report]. In addition to the data, a Quality Assurance Project Plan (QAPP) must be submitted separately. For more information about the assessment process, the data elements required for assessment, and directions for QAPP submittal, see the Surface Water Quality Assessment website.
