 abstract={This work aimed to evaluate groundwater potability for the population through geochemical assessment methods on the example of aquifers in Krasnodar city. In 2016 and 2019, on the territory of Krasnodar city (Krasnodar region, Russian Federation), a detailed geochemical analysis of groundwater quality was performed based on a total of 6000 samples, 3000 samples per each year. Samples were taken from 30 wells located at depths of up to 450 m in the layers of Anthropogen and Neogene stages. Quantitative analysis of wells according to the average water quality parameters showed that in 15 wells, the water condition met the MAC (maximum allowable concentration) standards in all layers. Water abundance between the layers of the Quaternary and Cimmerian stages is seven times as different (p ≤ 0.001) towards the latter, the hardness between the same horizons is ten times as different (p ≤ 0.001) towards the Quaternary stage and three times as different (p ≤ 0.05) in terms of solid residue. Thus, the water hardness and water abundance index vary significantly between the vertical layers. A strong positive correlation between the solid residue and the hardness values (Pearson correlation 0.93, p ≤ 0.05), and a negative correlation between water abundance and solid residue values (Pearson correlation –0.83, p ≤ 0.05), as well as between the hardness and water abundance values (Pearson correlation –0.81, p ≤ 0.05) was recorded. These findings can be used for regions with similar deposits of rocks and aquifers.},
