Certification Process:

  • Certification year runs from 1 July to 30 June. Renewal application packets are due by 30 May
  • There are two types of certification:
    • Direct Certification, which requires an onsite inspection

  • Laboratory third-party onsite audits are required at least every three years, whether they are performed by ADEC or another certifying agency (for reciprocity).
  • Completed application packets do not automatically guarantee certification for drinking water analysis.  This department will determine the certification status of a laboratory after final review of all submitted information. Following review, a State of Alaska Certificate along with the Scope of Accreditation will be issued identifying the status of approved methods/analytes.

Application Timeline:

  • New applications can be submitted at anytime
  • Renewal applications and fees are due and must be postmarked no later than May 30th of each fiscal year.
  • If a completed application and total fees are not submitted by May 30th, the laboratory will not be recertified on July 1st. Processing of applications received after May 30th will be prioritized based on date of receipt and may take up to 30 days to process depending upon the number of late applications.

    7. Current Proficiency test (PT) for the methods requested (must be performed within the previous 12 months)
      • An approved PT provider must be used (Quick Link on the left.)
      • The certified laboratory must successfully analyze water supply (WS) performance and/or water pollution (WP) testing samples annually for each certified parameter by each method. 
      • A recent/current PT (for renewal) is one where the study CLOSE DATE less than twelve months old) by the May 30th deadline.
