The transboundary transport of pollution by channel water flows causes environmental–economic losses in territories located in the lower reaches of rivers. In this case, very serious problems arise not only in the streams that cross state borders, but also on the borders between entities of the same country. The first problem is the reliability of water quality estimate against the background of considerable instability of hydrological regime and based on existing monitoring systems. This problem is considered in the case of the transboundary Ural River. An algorithm is proposed for the formation of a constructive dialogue between interested parties by taking into account the statistical characteristics of the measurement results obtained at neighboring sites of hydrochemical observations. It is shown that in this case a threshold of distinguishability of the controlled indicators should be taken into account and the errors of the 1st and 2nd kind are to be regulated. It is demonstrated that economic losses that result from the lack of constructive relations between the parties regarding the estimation of the controlled indicators can be determined.
