On the water quality degradation of the séraïdi springs, Edough mountain (NE of Algeria)
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 3
Abstract
This work investigates the water quality characteristics of the Séraïdi springs using old and recently gathered analytical data in order to understand their vulnerability to pollution. The synthesis of analytical and multivariate statistics results allows a hydro geochemical and microbiological characterization of spring water in the Séraïdi region. The results show that this forested, humid and heavily fractured area contains a shallow aquifer highly vulnerable to pollution from anthropogenic sources. Physical and chemical analyzes of major elements indicate that the overall mineralization is low to moderate and is closely related to magnesium, calcium and sodium chloride salts with significant nitrate and sulfate contents. This global mineralization is controlled by soil leaching during high water periods, acid hydrolysis phenomena of underlying rocks and human activities. Recent microbiological test results highlight the presence of Escherichia coli, Clostridia and total coliforms in water. The outbreak of these microorganisms in some spring waters points out that groundwater is exposed to fecal microbiological pollution of human and/or animal origin. This water quality degradation tends to seriously impair the physical-chemical and microbiological quality of water. It constitutes a health risk to the local population and those in search of supposedly fresh and high quality water.
