ÉVALUATION DE L’INDICE DE POLLUTION ORGANIQUE DANS LES EAUX NATURELLES CAS DE LA RÉGION D’EL TARF (NORD-EST ALGERIEN)
Journal Title: Larhyss Journal - Year 2011, Vol 9, Issue 9
Abstract
Pollution is a serious environmental problem because of dumped waste into rivers and the sewage was untreated represent the main source of organic pollution of waters. The region of El Tarf is located between latitude 36 ° 75'00 "and longitude 08 ° 16'66" to the extreme north east of Algeria. The analysis followed in the different observation points has been the subject of data processing by the mapping of organic pollution of natural waters in the region, which tells us about the influence of discharges and water quality through an index of organic pollution which is calculated using the method of Leclercq and Maquet, (1987). The principle is to spread the values of the pollutants in 05 classrooms to determine from its own the class number corresponding to each parameter to be averaged. The interpretation of the map showing the various parameters of organic pollution of natural waters results in contamination or not those waters the map shows that the various natural waters in the region of El Tarf pass from one grade to another.
