FIELD: measurement technique.
SUBSTANCE: invention refers to monitoring and rapid methods for evaluation of surface water body contamination level by means of bioindication methods using macrozoobenthos as indicator. The method includes extraction of indicator related to macrozoobenthos from water medium, its identification, determination of water body contamination level through evaluation of water rating and saprobity depending on indicator while wigglers of Tanypodinae subfamily (Diptera, Chironomidae) of natural water body are selected as the indicator, their species belonging is determined according to which water body rating and saprobity is defined depending on presence of particular species of wigglers from specified subfamily.
EFFECT: high accuracy and simplification of determination is achieved.
