چكيده لاتين :
Pollution and declining quality of water resources reduce usable water
resources, weaken economic development and threaten human health. In
this study, groundwater quality was studied and analyzed in Ardabil
aquifer. For this purpose, 32 samples of groundwater sources in the
Ardabil plain were collected and the concentrations of major ions, minor
ions and some heavy metals were measured. Then, hydrogeochemical
factors affecting the groundwater quality of the study area were analyzed
using multivariate statistical methods, including correlation coefficients
and factor analysis. According to the correlation matrix, the
concentrations of metals such as arsenic, barium, scandium, silicon, zinc
and vanadium indicated a little correlation with the main ions. Therefore,
it can be concluded that the entry of these elements into groundwater is
due to human activities. In factor analysis, the groundwater quality
changes were affected by four main factors with 77.31% of the total
variance of data in Ardabil plain. The results of factor analysis showed
that the first factor was lithogenic, the second and third factors were
lithogenic and anthropogenic, and the fourth factor was just
anthropogenic. The results showed that the concentrations of heavy metals
such as arsenic, barium, scandium, silicon, vanadium and zinc did not
have a high correlation with the main ions, so the presence of these
elements could be due to human activity. Also, the greatest effect on
groundwater hydrochemistry in the study area was related to magnesium,
sodium, calcium ions and electrical conductivity.
