Which treatment technique is NOT included in ADEQ grading a water facility?

• A. Coagulation-Flocculation
• B. Disinfection
• C. Activated Charcoal
• D. Filtration

Answer: (C)

In ADEQ Grade 1 grading, the focus is on the essential treatment steps typically required in a conventional water treatment train: coagulation-flocculation to help remove particles, followed by filtration to physically separate them, and disinfection to inactivate pathogens. These are the core techniques that the exam expects you to understand and apply for basic plant operation and compliance. Activated charcoal, or activated carbon, is used in some facilities for taste, odor, and certain organic removals, but it isn’t part of the standard set of treatment techniques that the Grade 1 grading emphasizes. It’s more of a supplemental or situational treatment option rather than a fundamental step required for basic grade-wide competence, so it isn’t included in the grading criteria.
