FIELD: ecology. SUBSTANCE: method involves the steps of: measuring parameters of hydrophysical fields of a water sample to be analyzed, comparing them with permissible threshold values. If the measured parameters of sample exceed the latter, water samples are taken and preserved by introducing preservative into each sample. If the threshold parameters exceed measured ones, the water is passed through a sorption member for a predetermined time interval, through which then a solvent is passed. Then contamination of the solvent is measured and solvent is metered out the same way as water. EFFECT: enhanced reliability. 1 dwg
