GOLF COURSES IRRIGATION WITH UV-TREATED WASTEWATER IN AGADIR CITY: IMPACT ON THE QUALITY OF LOCAL GROUNDWATER

Starting from 2010, a golf course located in Agadir city is irrigated with treated wastewater originating from M’zar wastewater treatment plant. To assess if the bacteriological and physicochemical quality of local groundwater is affected, groundwater quality of boreholes (G1) and (G2) were compared. Borehole (G1) is located in a golf course irrigated with treated wastewater while the borehole (G2) is situated in a golf course irrigated with freshwater. Samples waters were collected monthly from M’zar WWTP and from the two boreholes (G1 and G2). The faecal enterococci and faecal coliform were compted. The electrical conductivity and pH of waters samples were determined. Results of groundwater quality analysis show that no significant difference was recorded in groundwater faecal contamination indicators. Moreover, (G1) presents a significant decrease in the pH and significant increase in the electrical conductivity when compared with (G2)
