Laboratory Accreditation

(Lab Accreditation)

What is the Purpose of this Accreditation?
To become accredited. Laboratories that submit analytical data from the analysis of environmental or drinking water samples to Ecology, the Department of Health, or other entities requiring the use of an accredited lab must be accredited. Environmental data includes data submitted for the purposes of compliance with NPDES or state waste discharge permits.

To become accredited, a lab must submit a comprehensive application, Quality Assurance (QA) manual, and pay a fee. Also, the lab must successfully analyze blind proficiency testing (PT) samples and undergo an on-site assessment. Continued accreditation requires the lab to submit annually an application, successfully complete semiannual PT audits, and undergo periodic on-site assessments.
