Degradation of water quality: the case of plain west of Annaba (northeast Algeria)

Abstract

In the world, the water quality is undergoing deterioration due to urban and industrial wastes, and intensive use of chemical fertilizers in agriculture. Unfortunately, as in most countries of the world, Algeria is experiencing a severe crisis of its environment apart from the problem of depletion of water resources. The plain west of Annaba is particularly subjected to a general industrial pollution. The pollution problem in this region has really started to become worrying not earlier than in 1980, when the economic crisis has led some industrial units to sacrifice the “Environment” criterion for the benefit of the production. We were particularly interested in this work in waters of the superficial aquifer and wadis like Boudjemaa, Bouhdid, Sidi Harb, and Forcha whose waters are most often used to irrigate the surrounding agricultural land. Comparison of analytical results from two periods – 2006–2016 for the: EC, pH, Ca2+, Mg2+, Cl−, NO2 and 2006–2010 for the: Fe, Cr, Cu2+, Pb+ show a degradation of water quality in this region, which represents a very vulnerable area with a risk to pollution of groundwater.

The quality of surface waters of the dam reservoir Mexa, Northeast of Algeria

“…Water resource protection is one of the most essential concerns of any environmental policy [ATTOUI et al 2016]; water becomes a global strategic issue whose management must essentially integrate into a sustainable development policy perspective [ALLAL-GUA et al 2014]. In fact, some assert that it will be a war issue, in the third millennium, as it is the case for oil in the past and today [GARCIA 2006].…”

Application of expanded polystyrene filter for tertiary treatment of domestic waste effluent in the UK

“…Presently, there is a growing attention being paid to the quality of water in urban areas [BARTNIK, MO-NIEWSKI 2016] as it is greatly affected by the impact of urban and industrial effluent [ATTOUI et al 2016]. Insufficiently treated effluent leads to pollution not only of surface water but also groundwater [SHIRAZI et al 2015;SMOROŃ 2016].…”

The Effect of Agricultural Activity on of Water Quality in the Jasienianka Flysch Stream

“…Mean electrolytic conductivity of water in all points exceeded the limit value of 309 µS · cm -1 for class II stated for the abiotic type 12 in the Minister of Environment Regulation of 2016. These values were much lower than the ones obtained by Attoui et al [2016]. Mean concentrations of dissolved solids fluctuated from 251 mg · dm -3 in the headwater area to 272 in the middle part of the stream (Table 1 .…”
