Research on the quality of natural water of zhongar-alatau and altynemel national natural parks of the almaty region, Republic of Kazakhstan

The relevance of this research is connected with strengthening of anthropogenic and technogenic impact of pollutants on the biosphere in the Republic of Kazakhstan and in the world. The greatest influence of ecotoxicity is experienced by the water environment, being the final reservoir of the most pollutants. Over the past 25-30 years, the structure of water use has changed, which is expressed in a sharp increase in the social component of water use. The share of household and drinking water supply increased from 11% in 1980 up to 28% in 2018. In this connection, there is a real problem of drinking water quality, which is determined by contamination of natural water, unsatisfactory water treatment at water supply stations, secondary pollution in spreading networks. The article presents the results of physico-chemical indicators of the quality of natural water and experimental studies in Zhongar-Alatau and Altynemel National Natural Parks. Quality control of natural water was carried out by the basic laboratory of the Testing Center of Taldykorgan branch of Joint Stock Company “National Center of Expertise and Certification”. The laboratory was certified by the State Standard of the Republic of Kazakhstan for the right to carry out analyses of water sources and drinking water in all respects according to state standards. Experimental conditions: air temperature-20ºС, relative humidity-71%.
