Investigation of the mutual influence between a polluted river and its hyporheic

This paper describes investigations of fundamental biological and pratical importance. Interstitial subterranean water (hyporheic) which is near a polluted river in a plain is the subject of the study. The water is becoming increasingly important as a source of drinking water. The relation of the hyporheic water to the physical, chemical, bacteriological and faunistic characteristics of the river is discussed.
