Abstract： In the face of deteriorating environmental conditions in the world, water quality control is an urgent task. It can be solved by creating sensors with high accuracy and low cost, which requires the development of fundamentally new radiophysical methods that take advantage of the optical, microwave and millimeter wavelengths that have a significantly greater sensitivity to low concentrations of pollutants and a lower inertia. The article presents prototypes of measuring cells of the microwave and optical ranges as well as the results of an experimental study of water of various degrees of pollution with their help. The results show that the use of the highly sensitive method of capillary-waveguide resonance makes it possible to detect the presence of micro impurities in water with concentrations up to 0.1% and to identify water even from sources of various natural origins. In addition, the use of measurements at several frequencies in the optical range will make it possible to solve the problem of creating water control sensors with high sensitivity to pollution and low cost. It can be concluded that the possibility of complex use of multiwave sensors (optical, infrared and microwave ranges) allows to increase the sensitivity and reliability of water quality assessment.
