چکیده

This research work was performed within the framework of project titled “The survey on drinking water quality settlement areas Tuv province, conclusion and recommendation” implemented at Institute Geography Geoecology, MAS in 2021, some results are summarized this article. We took totally 16 samples from supply wells center 8 soums. Performed by physicochemical, micro-elements, bacteriological analysis, determined chemical composition, pollution parameters composition. underground evaluated calculating index (WQI). As regards anions, first most prominent types Ca-[HCO3] (50%), second Х-[HCO3] (43.7%), third Ca-[HCO3-SO4 2- ] (6.3%) groundwater dominated mixed type water. From study results, case mineralization, 50% surveyed locations belongs to fresh, freshly or relatively high mineralization. In hardness, 43.7% softish, moderately hard remaining 6.3% hard, respectively. According analysis microelements, uranium concentration (U 33-176 µg/l) 1.1-5.86 times higher than standard, strontium (Sr 2021µg/l) 21 μg/l more (1 out 16), nitrate (NO3 63.0 mg/l) 1.26 16) total samples. Total 11 collected sampling points covered does not meet requirements Drinking Hygienic requirements, assessment safety MNS 0900:2018 standard any several parameters. Төв аймгийн баруун урд бүсийн ундны усны чанар, найрлага Хураангуй: Хүн ам баталгаат ус хангамжийн үйлчилгээ хүртэж байгаа эсэхийг тогтоох зорилгоор чанарын судалгааг аймаг тус бүрээр судалсан. Энэхүү судалгааны нэг болон 2021 онд хэрэгжсэн “Төв төв, суурин газрын судалгаа, дүгнэлт, зөвлөмж” гэрээт ажлын хүрээнд 27 сумын худаг уст, цэг хамрагдан физик, химийн үзүүлэлт бичил элемент, бактерлогийн шинжилгээг хийж шинж найрлага, бохирдлыг тодорхойлсон үр дүнгээс нутаг дэвсгэрээс нийт цэгийн нарийвчилсан дүнд боловсруулалт хийж, чанар найрлагыг тогтоон, доорх усыг индекс (УЧИ-WQI)- ээр үнэлсэн. Судалгааны харахад талбайд гидрохимийн чанараараа Ca-[HCO3], 45.81% Na-[HCO3], 12.51% Ca-[Mg]-HCO3, холимог-[HCO3] найрлагатай тархсан байна. Судалгаанд хамрагдсан уст цэгүүд нь эрдэсжилтийн хувьд цэнгэг цэнгэгдүү ангилалд хамаарч бол хатуулгийн маш зөөлөн, зөөлөн байхгүй, зөөлөвтөр, хатуувтар, хатуу устай цэгүүдээс 3 цэгт ураны мкг/л) агууламж стандартаас дахин их, хүнцэл (As 36.7 1 худгийн усанд 5.86 стронций мкг/л нитратын ион ( NO3 - мг/л) их илэрсэн Шинжилгээний дүнгээр буюу 68.75% аль юм уу хэд хэдэн үзүүлэлтээрээ “Хүрээлэн буй орчин, эрүүл мэндийг хамгаалах аюулгүй байдал.
