    ELAP Requests Comments on Proposed Changes to Structure of Fields of Testing Worksheets (1/10/17)

    ELAP is requesting comments regarding proposed changes to the structure of ELAP's Field of Testing (FOT) worksheets.

    The Environmental Laboratory Technical Advisory Committee (ELTAC) is recommending a structural change whereby ELAP's FOT worksheets are arranged by analyte (as opposed to the current version where FOT's are arranged by method). View the draft FOT 101: Microbiology of Drinking Water for an example. ELAP is requesting general feedback on the proposed structure, as well as comments on overall ease of use and practicality.

    Please submit comments to ELAPCA_Comments@waterboards.ca.gov and indicate "Proposed Changes to FOT Worksheet Structure" in the subject line.
