Environmental impacts on groundwater quality in el Obour City and its vicinities East Cairo-Egypt

الملخص EN

el-Obour is a newly constructed city in the desert located 25 km east of Cairo, Egypt.

As a result of expansion of various environmental activities in the city, water logging problems have emerged.

An attempt was made in the present study to identify the source(s) of water logging problems that affects water resources in the investigated area.

Twenty-seven water samples that were collected from the study area represent the available water sources such as surface water, perched groundwater (class I), municipality or public water (class II), wastewater (class III) and deep groundwater of the Miocene aquifer (class IV).

Complete chemical, biological and microbiological analyses were performed for water samples.

Results of our study show that major, minor and heavy metal elemental distribution reflect that the source of water logging may be pollution from municipality or public water (class II) or leakage from the sewage or industrial wastewater system (class III).

The results of biological and microbiological analyses of the water samples reflect leakage from sewage, irrigation or industrial wastewater system and show that class III waters are characterized by high concentrations of trace and heavy metals, which affect the quality of deep groundwater of the Miocene aquifer.
