Levels 1-4 Water Operator ExamsTrained and certified operators are necessary to ensure that the systems are managed in a manner that fully protects public health and the environment. The OARs for certification (http://public.health.oregon.gov/HealthyEnvironments/DrinkingWater/Rules/Pages/rules.aspx#cert) stipulate that the qualifying experience for applicants for certification as a water treatment plant operator must attain at least half the required operating experience at a public water purification plant that uses complex filtration technology and is not more than one classification lower than the level of certification they are seeking. In other words, if you have only worked for a Class 2 treatment plant, we allow you to apply for a Level 3 certification but not a Level 4 certification. If you move on to a Class 3 plant, then you must have 1/2 the qualifying experience (at the Level 3 plant) before allowing to apply for a Level 4 certification. Reciprocity from state-to-state ensures that the operator have the operating experience for which they are certified.For additional please visit:
