THE IMPACT OF SEPTIC TANKS ON THE GROUNDWATER: SURVEY RESULTS IN A RURAL AREA OF MOROCCO, AFRICAS. EL HALAS, B. CHARAF, M. OUHSSINE AND B. HSI
In order to deduce the impact of septic tanks on the water, the soil, the vegetal, animal and man, a survey was conducted at Sidi Ayache region in the province of Kenitra, Morocco. The purpose of this survey is the evaluation of the quality of the groundwater in the study area and to have through the testimony of the inhabitants, a return on the various uses of water wells. Four hundred and thirteen households were affected by this questionnaire. Preliminary results of the survey revealed that most people doubt the quality of well water. They claim that all diseases observed in the region could come from the poor quality of water wells having a bad taste and therefore not potable. It was also observed that in some households, there is no respect of distance between septic tanks and wells. There is even a household that has transformed the well to a septic tank. This behavior and others may cause adverse effects on the components of the environment. To confirm this hypothesis, we envisage achieving analysis of well water in the laboratory.
