El Sadat City is a new urban community established in the Western Desert of Egypt near the Hile Delta. The district of the city and vicinity is covered by a thick Pleistocene section of sand and gravel facies based by a thick Pliocene layer of plastic clays.An area, selected from the previous hydrological studies, was covered by 27 deep electric soundinss in order to locate the fresh water aquifers that may occur and to identify the probable geometry of these aquifers. Data collection, reduction and analysis were achieved in site using field computers ~o produce the equivalent layering model and the n-layers model of each sounding. The models were used to construct the subsurface true resistivity bar sections as well as the resistivity contour sections along three profiles using the set of soundings located on each profile. Besides, subsurface horizontal contour sections were produced at different depths.The interpretations of the analysed data revealed that most of the Pleistocene sediments act aa a fresh water aquifer which is charged from the water circulated from the Delta. It was also possible to distinguish subsurface gravel rich channels which yield most of the groundwater potential in the area. The depth to fresh groundwater ranges from 35 m to 65 m according to the relative topography of each sounding site. In addition, the study indicated that another saline aquifer, of probably fossil water, occurs at greater depths beneath the fresh water aquifer. The two aquifers are vertically separated by a thick layer of impervious formations. Recommendations for drilling, in some selected Sites, were reached from the present study. The subsequent drilling operations resulted in the construction of a number of heavy duty water wells (water field B with capaCity of 70,000 m 3 /day) which satisfy the water demand ot the city.

Research objectives: Determining changing degree in the performance of studied families for the following jobs: socialization, social control, educational function, after the work of their heads in factories. Identifying the relationship between studied variables, and the degree of change in the performance of the studied jobs. Identifying the problems facing families researched as a result of their heads' work in sadat city factories and proposals to overcome them. The research was carried out on a sample of 400 workers. Data were collected using a personal questionnaire during May and June 2021, and classified, quantitatively processed, and analyzed using numerical inventory tables, frequencies, percentages, middle class, simple correlation factors, and a chi square test. The results were as follows: Respondents see that the level of change in the studied functions as a result of the work of the head of the family in sadat city factories is high and average respectively 92.25%, 94.75%, 88%. 91% of respondents see the level of changes in the jobs studied overall is high and average. There is a relationship between respondents studied variables and the change in the performance of families jobs. Problems facing studied families as a result of their heads' work in Sadat city factories were length of working hours. The most important proposals of the respondents to overcome the problems they face were: reducing quarrels between children, agree on who manages the affairs of the house.
