To evaluate groundwater contamination in the industrial area, piezometric level and physico-chemical analyses have been monitored for 8 months using 17 piezometers. Groundwater is shallow (0.8 - 7 m) and found in the relatively permeable miopliocene alluviums comprised of sand and gravels. The industrial effluents were sampled from a drainage channel within the industrial zone. The average results of physico-chemical analyses (BOD5, COD, TSS, Total Hydrocarbons and some metals) showed an important qualitative degradation of the groundwater, especially in the parts situated in the down gradient area and in direct proximity of the drainage channel. Key factors influencing the extent of groundwater contamination include the depth of the water table, permeability of the soil and therefore infiltration rate. In order to prevent further deterioration of groundwater quality, effluent must be transported via pipes or impervious channels for treatment prior to discharge.
