Assessment of eco-chemical state of Chiatura municipality natural waters for echo-economic
Keywords:
Kvirila River, spring waters, hydrochemistry, manganese, pollutionAbstract
Hydrochemical and microbiological characteristics of Kvirila River water and spring waters of territories adjacent to Chiatura municipality manganese processing enterprizes have been considered in the work. Kvirila River water and spring waters contaminated with different ingredients have been identified: Kvirila River water belongs to the category of medium-salt (average mineralization) waters; manganese concentration equals to 2.56 mg/l, which comprises 25.6 MPC (maximum permissible concentration). This is stipulated by the fact that Kvirila River below the enterprise is polluted with waste waters resulting from extracted ore washing, which are dumped into Kvirila River; total Mn content in suspended particles and bottom sediments is very high compared to the background level; spring water belong to the category of medium-salt and highly mineralized waters; among polluting ingredients nitrites and sulfates are distinguished by their high content; manganese content is within the norm; no contamination according to microbiological parameters is registered.
