   Summary
    ◦ Recycled Water Policy includes participation from
      a variety of agencies
    ◦ Different programs and applications require their
      own methods and analytes to meet regulations
    ◦ Lab Accreditation is by method and matrix
    ◦ Permits attempt to cover as much as possible,
      even chemicals of concern that do not appear on
      any previously regulated methods
