Which document provides the certification requirements for water system operators in Wisconsin?

• A. NR118
• B. NR102
• C. NR114
• D. NR120

Answer: (C)

NR 114 is the part of Wisconsin’s Administrative Code that governs who can be a certified water system operator and what they must do to stay certified. It lays out the certification requirements, including eligibility, the certification levels, how to obtain certification (testing and required training hours), renewal timelines, and continuing education or recertification rules. Because the question asks which document provides the certification requirements for Wisconsin water system operators, NR 114 is the authority that sets those requirements. The other sections address different regulatory topics and do not establish the operator certification requirements.
