Example bounds establish no compliance or diagnosis. Ambient, drinking-water, effluent, crop, food, air and noise standards are not interchangeable. A censored result is not an exact zero.
Proposed checking role. Community representative, service specialist and safeguarding reviewer.
After the action. Follow-up compliance, exposure/service condition and corrective closure.
