In partnership with Pennsylvania's 15 Approved Examination Providers, DEP and the Board are offering 45 exams for approximately 2,500 examinees. These numbers are dramatically higher than previous years.

DEP's goal is to grant all interested operators the opportunity to register for an exam and obtain certification. The operation of drinking water and wastewater treatment systems is an important profession that is integral to the state's economic growth and the protection of our citizens' health, drinking water, and the aquatic environment. The mission of the certification program is to ensure that competent certified operators oversee the operation of every drinking water and wastewater system in the state.
