GROUNDWATER POLLUTION RISK ASSESSMENT IN SEMI – ARID REGIONS (CASE STUDY: SADAT CITY)

Abstract
Abstract
Inarid and semi-arid regions, such as in Egypt, groundwater is considered one of
the main sources of water where there is a lack of surface water, like in the
western and eastern deserts. Groundwater is usually used in various purposes such
as domestic, industrial and agriculture. Due to the rapid expansion and
uncontrolled plans of the reclamation lands(national projects and private farms)
and new communities, especially in the Delta fringes. Accordingly, groundwater
in such new cities should be wisely used, monitored and protected from pollution
sources. Pollution sources in these cities come from industrial, agricultural
seepage, leakage from wastewater treatment plants and sewer systems.
The area of interest in this study is El Sadat city, which is one of the largest and
relatively new industrial cities in Egypt. It has been constructed more than 3
decades ago. Itis
locatedin theWesternNileDeltafringes,onthe Cairo-
AlexandriaDesertRoad between km93 and km 103 fromCairo.El Sadat city and its
surroundings mainly depend on groundwater for domestic, agricultural and
industrial purposes. The industrialareais locatedin theeasternportion ofthecityand
consistsof more than450factories.
Sadat city is located where the two-aquifer systems overlap (the Nile Delta aquifer
and Moghra aquifer). The two aquifers are separated by a semi-pervious clay
layer ranging in thickness from 5 to 10 m. Due to the difference in hydraulic
heads, groundwater recharge occurs from the Quaternary aquifer to the
Moghraaquifer. The regional direction of groundwater flow is northeast southwest.
Sadat cityis considered a vital area in the western Nile Delta fringes due its various
industrial and agricultural activities; therefore, it is needed preventive and
protective measures. To maintain groundwater potential in terms of quantity and
quality in order to sustain the development plans of this city at present and future
as well.
This research study is dealing with a critical problem as Sadat Industrial City
suffers of leakage from industrial zone, which is very close to the wells field. This
means that undesirable heavy elements still exist and may pollute the groundwater
on the future and cause health problems.
ArcGIS and Visual MODFLOW have been used to simulate the groundwater flow
movement for the area of interest. The final result of the calibration has been used
