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.
