About the causes of water turbidity in the river Yasyl

This article considers the problem of turbidity of the waters of the Yasyl river caused by erosion of particles of gypsum from karst rock. Samples were taken at various sites in the river Yasyl. The composition and size of particles of the dispersed phase of water samples in the dry residue were determined by X-ray phase analysis and photon-correlation spectroscopy. The phase composition of suspended particles and oil products was monitored, and the mutual influence of these parameters was established. Various salts of water hardness were founded, depending on the presence of semi-anhydrous calcium sulphate, there is an equilibrium with dihydrate. In addition, the causes of water turbidity disappearance over time have been established.
