AWWA Offers Free Op Cert Exam Prep Materials
Our colleagues at AWWA are offering two helpful reference sheets – one on math and one on chemistry – that operators may find useful as they study for their certification exams. As AWWA says, “These reference sheets contain useful formulas, conversions and other pieces of information that you may need to know for your operator certification exam. Check with your state for more specific instructions on what you need to know.”
