Summary:
Spread in quantitative characteristics of water quality often exceeds their average value, with measurement error being comparable with the scatter, and the error caused by insufficient sample size being comparable with accuracy. Under these circumstances, interpretation of the results of laboratory research requires the use of such methods asqualimetry, which include intervalnonparametric and parametric estimation based on the mathematical tool of the theory of tolerance intervals. Method for probability estimation of controlled parameters exceedance for water risk assessment has been developed. The method has been tested in order to fix an acceptable level of risk, and to establish trust-based business relations on water servicemarket. Recommendations to limit the uncertainty of the results of water quality assessmentmanagement have been made.

Keywords: lossofquality, statisticalhypothesis, toleranceinterval, waterqualimetry
