AWWA Water Operations VIP Certification Exam
AWWA — AWWA (American Water Works Association) does not administer a single national certification exam; water operator certification is managed at the state level, but AWWA's training materials, manuals (e.g., Water Treatment, Water Distribution), and competency frameworks define the standard body of knowledge tested across all U.S. state water operator exams (Distribution Grades 1–4 and Treatment Grades 1–4). This exam mirrors the breadth and difficulty of a Grade 3/4 combined distribution and treatment operator certification exam as aligned with AWWA standards.

The jar tests show that the optimal coagulant dose increased from 12 mg/L to 38 mg/L. The operator also notices that settled water pH dropped from 7.2 to 6.6 at the higher coagulant dose. What is the MOST appropriate corrective action?
