Assessment of groundwater chemistry and bacteriology in the Couloir Fes-Taza aquifer
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 10
Abstract
The Couloir Fez-Taza aquifer has an important drinking water potential resource for supply of Taza city and its neighboring centers and also for the development of agriculture the corridor. In order to determine the origin, type and impact of pollution on the aquifer, many water samples were taken at 26 different points: 12 springs, 10 wells and 4 drilling wells. Various physico-chemical and bacteriological parameters were analyzed. The results show the existence of a chemical and microbial pollution of the water which is related to agricultural and domestic activities. This contamination was demonstrated by levels that’s exceeding the recommended standards for human water consumption (according to Moroccan standards NM 03.7.001). Indeed, 76.92%, 19.23% and 11.53% of the analyzed samples have consecutively orthophosphate, ammonium and nitrate pollution. 34.6% are under oxygenated and 53.84% are contaminated by lead. Concerning bacteriological analysis, ground waters samples show that 88.5%, 54% and 77% are consecutively contaminated by total coliform (TC), fecal coliform (FC) and fecal streptococcus (FS). It appears from these results that the water of Couloir Fez-Taza aquifer could present a healthy risk for its users in long terms.
