In this article, the purpose of the research was to study the ecological characteristics of groundwater and central water supply used for drinking and economic activity of the Kievka village. The hydrochemical indicators of the samples were determined with conventional methods, and performed on 16 indicators: pH, electrical conductivity, suspended solids, dry residue, chlorides, sulfates, phosphates, total hardness, sodium, ammonium nitrogen, nitrites, nitrates, chemical oxygen consumption (COD), anionic surfactants (APAS), total iron, and manganese. While assessing the hydrochemical state of drinking water in the village of Kievka, it can be noted the "Altyn-dan" kindergarten and the Kiev secondary school No. 3, exceed the MAC which is determined by certain indicators. As a result of microbiological studies of the water samples from the village of Kievka, it was revealed that the total microbial number is normal. It was determined that a different number of fungi and actinomycites were present in all samples. At the initial concentration, a large concentration of fungi was observed in all samples.

The possibility of using halophytic plant species for remediation of saline soils in Kazakhstan is considered. In this regard, the purpose of our research is a comparative description of the germination of some halophytic plants of Pavlodar region in saline soils of European calf (salicornia europaea L.), Aksora (suaeda salsa Pall.), Tumpek sarzasan (halocnemum strobilaceum Pall.). The article aimed at selecting the most active seeds for the salt by germination indicator using some halophyte plants seeds. A comparative description of the germination of European calf (salicornia europaea L.), Aksora (suaeda salsa Pall.), Tumpek sarsazan (halocnemum strobilaceum Pall.) near Lake Maraldy of Pavlodar region was given. All of these plants have been shown to be true halophytes, and each of them can be used to reduce soil salinity. For this purpose, it can be recommended to the use European calf (salicornia europaea L.) of saline lands of not only in Pavlodar region, but in most saline areas of Kazakhstan.
