The article carried out a hydrochemical analysis of the content of cations and anions, as well as heavy metals in different volume salt reservoirs of the Mangistau region: the Caspian Sea, the Salt Lake Malaya Oymasha and the Radon thermal spring. The results of the analysis show that in all three reservoirs the contents of such heavy metals as chromium, manganese, cobalt, nickel, copper, lead, zinc and cadmium do not exceed the maximum permissible concentrations and are in minimum contents. Hydrochemical analysis shows that in terms of cation content, the minimum values are characteristic of potassium and sodium ions and the data for all three reservoirs are almost the same and are about 3 mg/kg for potassium and 9 mg/kg for sodium, respectively. The content of calcium and magnesium in two reservoirs is higher than magnesium ions, in the Salt Lake Malaya Oymasha and the Caspian Sea. In a radon hot source, calcium ions are higher, and magnesium is 3.5 times less. Salt Lake Malaya Oymasha which is 1.2 times higher than in the Caspian Sea and 5.6 times in comparison with the Radon thermal source. For anions, the highest values are characteristic of chloride ions, which is 8.14 times higher than the content of sulfate ions and 24.8 times of hydrocarbonate ions. Then, sulfate ions and hydrocarbonate ions are decomposed by the anion content. The analyses show that chloride and magnesium ions are the main salt-forming ions in the Caspian Sea, chloride and calcium ions in the Salt Lake Malaya Oymasha and the Radon hot spring in the salt reservoirs of the Mangistau region. The results of the analysis can be used for scientific research aimed at understanding the hydrogeochemistry of the region and the impact of anthropogenic activities on water resources. The quality of water in salt water bodies can affect the development of tourism in the region. The results of the analysis can help promote water bodies as safe and attractive places to relax.
