Prediction of the pollutants movements from the polluted industrial zone in 10th of Ramadan city to the Quaternary aquifer

Résumé

There are some sources of pollution of the groundwater such as the industrial, agriculture, domestic activities and the oxidation ponds that are considered collection points for waste disposal plants. The motivations to do this work were: (1) investigating the concentrations of pollutants in the oxidation ponds and well surrounding the 10th Ramadan city and (2) predicting the groundwater flow and the pollutant transport to the groundwater from the pollution source using a numerical simulation (MODFLOW-2000 with MT3D code). The samples of groundwater were collected from the wells that spread around the studied area as well as many samples were collected from the oxidation ponds to investigate the concentrations of pollutants in these samples and predict the pollutant transport to the groundwater over 30 years. The results illustrated that the ion concentration of most samples from the oxidation ponds resources contained Al 3+ , Fe 2+ , Sr 2+ , Ni 2+ , and Cr 2+ which were exceeding the acceptable limit of WHO (International standards for drinking water, WHO, Geneva, 1996 ) standards. The results also demonstrated that most of the analyzed groundwater samples are polluted with strontium (Sr 2+ ), aluminum (Al 3+ ), and iron (Fe 2+ ). The simulation predicted that the pollutants movements toward the northeast of the study zone over a long-term period (30 years).
