Risk to contaminate drinking water supply sources during rainfall and vegetation periods

The results of research on the change of a chemical compound in groundwater depending on the time of year and quantity of precipitation and the results of monitoring the condition of irrigated lands of cotton sown regions in Tajikistan on the level and degree of groundwater mineralization are presented. The essential influences of the irrigation of the lands in vegetation periods on quality of groundwater are observed. In the present work the monitoring of influence of the Anzob mountain-concentrating industrial complex wastewaters on quality of water of the river Zeravshan were carried out. For this purpose were made the physical and chemical analysis of tests of water selected from points located above and down from an industrial complex wastewaters dam. Results of comparison of the analysis of waters have shown about absence of essential pollution of waters of the river by wastewaters of the Anzob Mountain-concentrating Industrial Complex (AMCIC
