The groundwater is a substantial source of fresh water and has been used for various
anthropogenic uses. The aim of this work is to investigate groundwater quality and type in
kubaysa and AL-Waffa areas, Anbar, Iraq using multivariate statistics approach. The
groundwater was sampled from ten wells for each region during the period from October
2018 to March 2019. The levels of T, TUR, pH, EC, TDS, DO, COD, TH, Na+, K+, Ca2+,
Mg2+, NH4+, Cl-, F-, SO42-,, NO3-, HCO3-, S-2 and SiO2, were measured. The majority of the
physicochemical parameters exceed the permissible guidelines. Pearson’s Correlation
technique, multivariate statistical tools such as cluster analysis and principle component
analysis were applied to determine the groundwater type. For Al –Waffa area, the EC had a
positive strong correlation with TDS, Na+, Cl-. The TDS had positive strong correlations
with NO3-. TH and Ca2+ possess a very good positive correlation between each other and
positive strong correlations with SO42-. Sodium has positive strong correlations with k+ and
Cl-. For the kubaysa area, the EC has positive strong correlations with TDS, Na+, K+ and
Cl-. The TDS have positive strong correlations with TH, Ca2+, Na+, K+, Cl-, and SO42-. The
piper diagram indicates that the groundwater types in AL-Waffa and kubaysa regions are
Ca2+, Mg2+, SO42- and Ca2+, Mg2+,Cl-, SO42 respectively. The results showed unsuitable
water for drinking purposes and need to be treated. The main finding of the current study
is a suggestion to use the multivariate statistics technique in determining the groundwater
classification type as an alternative method for the piper diagram.
