metadata.name: dc.description.abstract
metadata.value: The main study task was dictated by the growth rate of water consumption, namely the development
  of new scenarios for the exploitation of groundwater for water supply purposes.
  The assessment of surface and groundwater quality in the area showed a tendency to increase
  mineralization, hardness, a number of chemical components (up to exceeding the limited
  concentration). Analysis and interpretation of long-term groundwater chemical data, as well
  as the intensity of surface runoff, within the study area, allowed us to identify anthropogenic
  influence on the amount of runoff. According to the results of the study, the growth of infiltration
  nutrition (due to the expansion of irrigation areas) is reflected into deterioration of
  groundwater quality. In addition, the existing water intakes are located within the city limits,
  which creates an additional threat of bacterial and organic pollution. The new scenarios of
  groundwater exploitation are based on the features of the hydrogeological section, the results
  of hydrochemical studies, the amount of groundwater reserves of individual aquifers, calculations
  of sanitary protection zones of water intakes. The Amwells module (ANSDIMAT
  software package) was used to estimate groundwater reserves, so an analytical model was
  created based on the actual material. Thus, an extremely demanded detailed characterization
  of the groundwater of the studied area was carried out, some of which are suitable for use as
  drinking water.
