Physico-Chemical and Bacteriological Analysis of Certain Wells and Sources of The Oulmes Water Table, Morocco

Abstract

Water is a constant concern of all times and places, becoming a question of life and death. It is threatened today by anthropogenic or natural pollution. These waters constitute the main source of drinking water supply for the city of Oulmes. The present study focuses on the hydrogeochemical and bacteriological characterization of certain springs and well water in Oulmes Town, Central Moroccan. The methodology adopted consists of characterizing the physico-chemical and bacteriological properties, by following the spatial variation of the contents of the water pollution indicators of certain wells and sources in the study area, and this, by companions of the samples which were carried out and was subject to analysis at the laboratory level according to evaluation techniques. The results of the physicochemical analyses revealed that the values of the parameters such as pH (6.72), temperature (16.99 °C), and Salinity (0.51 mg/L) conformed to the WHO potability standards. The bacteriological (Total coliforms (0 to more than 250 CFU/100 ml), Fecal coliforms (0 and 34 CFU/100 ml), fecal streptococci (0 and 37 CFU/100 ml) Pseudomonas aeruginosa (0 and 100 CFU/100 ml)) study confirmed that the water from the wells and sources showed pollution of bacterial origin. Using these waters for human consumption without treatment may endanger the populations with the risks of hydric diseases.
