The Risk of Assessing the Compliance of Water Quality With Established Requirements

Standard rules for assessing natural water quality indicators provide for measurements with an error, which is often commensurate with the absolute value of the controlled quantity. As a result, there are risks of an erroneous assessment of the compliance / non-compliance of natural water with the established safety and quality requirements. A simple technique for the quantitative study of such a risk is proposed. It is shown that its maximum level is limited to 50% when managerial decisions are made under conditions of complete uncertainty. A method for taking into account the considered risks in resolving disputable situations based on the available evidence is proposed.
