Résumé

Water quality is an important parameter that affects all aspects of ecosystem and human well-being
such as community health, food production, economic activities, ecosystem health and biodiversity.The objective of our work was to study the evolution of physico-chemical parameters of surface
waters of the two dams of eastern Algeria (Koudiat
Medouar and Babar), based on analytical results of
the ANRH during a period from january to december
2020.
Analyses were carried out on 10 physico-chemical parameters; descriptive analysis of the results
showed that the physico-chemical qualities of water
from the Koudiat Medouar and Babar dams comply
with Algerian standards for raw water.
The results have been treated statistically by
using the major issue analysis (PCA). The aim of this
multivariate modelling is to determine the main factors controlling the chemistry of these waters and
possible sources of contamination and pollution.
Our results reveal that the dam waters Koudiat
Medouar show a strong negative correlation with
OM, DBO5, NO2-, DR, COD, PO4-3. This is linked to
industrial and agricultural effluents and the discharge of domestic wastewater.
