VULNERABILITY OF SAISS GROUNDWATER RESOURCES FOR RENEWABLE DRINKING WATER PRODUCTION MOROCCO
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
The problem of water pollution affects the whole world including groundwater which is more susceptible to contamination by residues of industry, agriculture and domestic wastewater leading to the emergence of many serious epidemic and toxic diseases (methemoglobinemia, saturnism, fluorosis, cholera, typhoid, amoebiasis,…etc). The purpose of our present study is to evaluate the impact of agricultural intensification and discharge of untreated sewage on the physical, chemical and bacteriological water quality of SAISS’s groundwater (Saiss, Morocco). The physicochemical parameters followed are: T°C, pH, EC, NH4+, NO2-, NO3-, Cl-, F-, HCO3-, SiO2, SO42-, Boron, Dry Residue, Turbidity, Total Hardness (TH), Dissolved O2, Oxidisability and total and fecal coliforms of raw water from the boreholes. The results reveals averages of temperature (20°C), pH (6.47), electrical conductivity (785.1 µs/cm), Nitrite (0.0093 mg/L), Nitrate (21 mg/L), Ammonia (0.093 mg/L), Chloride (141 mg/L), HCO3- (5 meq/L), Total Hardness (13.9 meq/L), dissolved Oxygen (5.6 meq/L), Oxidisability (1.71 meq/L), Silicate (4.6 mg/L), Sulfate (17.7 mg/L), boron (0.0039 mg/L), Dry Residue (0.05 meq/L), Fluoride (2.2 mg/L), Turbidity (2.17 NTU). We also noted a total absence of fecal and total coliforms (0 UFC/100ml) in the waters of the tablecloth SAISS. This study shows that the physicochemical and bacteriological quality of the groundwater which is used as drinking water for the city of Kénitra and adjacent towns is generally good. However, high concentrations of nitrates in some wells (over 51.55 mg/L) are worrisome because of the serious health consequences (methemoglobinemia). For sustainable use, policymakers must protect the aquifer against the anarchic development of agriculture and spreading not reasonable enormous masses of pesticides and fertilizers.
