Effects of anthropogenic factors on groundwater ecosystem in Meknes area (Morocco)

The depletion of aquifer systems in arid and semiarid regions worldwide is causing acute water scarcity and quality degradation,and leading to extensive ecosystem damages. this study shows that by including environmental damages,especially the anthropogenic factors into the analytical results,results can change substantially depending on human activities. the analysis of water from wells and springs in meknes area,showed that their physicochemical and biological quality is largely influenced by the human activities,high values of electrical conductivity (13840 μs/cm) and low value of dissolved oxygen (2.88 mg/l) were recorded in p1 water. this well is located near the landfill. the analysis of the total wells and springs water fauna showed a great taxonomic richness with variations in time and space. the biodiversity decreases,in groundwater polluted by the waste,lixiviats and the landfill fauna disappears completely if the degree of contamination of groundwater is high. therefore of these strong requirements they are highly sensitive to any disturbance in their environment (both quality and quantity) and consequently their risk to be threatened are higher that turn to greater chances of extinction.
