Spatial and Temporal Variations in Surface Water Quality of the Dam Reservoir in the Guenitra Basin, Algeria

Abstract

The objective of the study was to assess physicochemical parameters of Guenitra dam. We investigate its water quality from March to May 2017 by monitoring some important physical (EC, turbidity and Total Hardness) and chemical (pH, Ca +2 , Mg +2 , Cl -, SO4 -2 and TDS) parameters and nutrients (nitrogen and phosphorus) contents. The results indicated that most of the physicochemical parameters from Guenitra basin were within or at the margin in comparison to the permissible limit of Algerian standards and WHO for drinking and irrigation water and therefore, may be suitable for domestic purposes, but it requires noticeable consideration due to extreme changes in climate and increase in pollution.

Physicochemical and Biological Water Quality Assessment of the Guebli River, Northeastern Algeria

“…Like nitrates, nitrites are highly present in a large part of the waters. 20 The presence of a high level of nitrite in water is an indicator of wastewater pollution. 21 The values of NO 2 -recorded in this study ranged from 0.02 mg/l for St.4 in May to 0.17 mg/l for St.2 in March (Fig.…”
