The procedure of arbitration water control

Summary

Measurement errors cause unavoidable differences between the actual and measured values of the investigated water parameters; from whence it is not possible to guarantee different laboratories, e.g. industrial and public water control, getting identical results. The procedure of evaluating and comparing the risks of getting false water quality reports by the two independent parties is suggested. On the basis of the procedure a method of resolving arbitration cases was developed provided the measurement results being compatible. Possible accounting for non-compatible results is considered including the use of reserve samples of the investigated water, standard samples or reference laboratories. Complete elimination of arbitration cases requires carrying out quality control by a single party concerned. It is shown that in this case the proper control is ensured on condition that «the principle of distributed priorities» is applied.
