The societies occupying the Nile Delta in the 4th millennium BC were not cut off from the neighboring regions of Upper Egypt and the Southern Levant. The Nile River, which served as a transport route between southern and northern Egypt, and the geographical proximity of the Southern Levant to the Nile Delta were probably both factors that allowed contact to occur between the regions. Whilst a significant number of Southern Levantine and Upper Egyptian imports have been found at Lower Egyptian cultural sites, the quantity of Lower Egyptian items from the same period found in the Southern Levant and in southern Egypt is more limited. This state of affairs did not occur by chance, which suggests that the scarcity of northern Egyptian finds outside Lower Egypt can probably be attributed to the nature of trade and the position of the Nile Delta in this period.Although our knowledge of the contact of the Delta with Upper Egypt and the Southern Levant is constantly expanding, many issues still remain unclear, including that of trading patterns. Archeological research currently being conducted in northern Egypt (mainly at Tell el-Farkha, Tell el-Iswid, Sais and Buto) has provided us with new material that adds to our understanding of the field. From the most recent excavation results, it would appear that from the very beginnings of its existence, the Tell el-Farkha site in the eastern Delta was as an important exchange center where the influence of the east and the south came together.The aim of this paper is to portray the interaction occurring between the Delta, Upper Egypt and the Southern Levant in the 4th millennium BC on the basis of material found at the excavation site of Tell el-Farkha in the eastern Nile Delta and to explain the role of the Nile Delta in political and cultural relations between these regions.

Egypt planned to reclaim large areas in both the Eastern and Western desert fringes of the Nile Delta with an increasing use of sewage effluent from Greater Cairo. The Gabal el Asfar farm which has been irrigated with raw to primary treated sewage effluent for a period of seventy five years was selected as a pilot area to investigate the groundwater quality. This farm covering 3000 feddan (1250 ha), is located in the sandy area northeast of Cairo. The main objective of the study was to assess the impact of agricultural application of sewage effluent on groundwater quality. Observation wells were constructed and field and laboratory measurements were carried out in and around the Gabal el Asfar area. The water balance and mass balances have been assessed. The study yielded useful recommendations to decrease the impact on groundwater quality and possible risks in Gabal el Asfar, concerning 1) type and amount of pollution from sewage effluent, 2) design criteria to control possible spreading of pollutants, and finally 3) the use of groundwater in the area. The following comprises the main conclusions:*Irrigation with sewage effluent had a positive impact on salinity of the initially brackish groundwater. On the contrary, groundwater quality is negatively affected from sewage effluent with regard to nitrogen contents (ammonium and nitrate), phosphate, heavy metals and faecal coliforms.*The drinking water limit for nitrate is sometimes exceeded. Moreover, faecal coliforms are found in water from all shallow handpumps in the area. The general suitability of the groundwater is therefore limited while the use of handpumps for drinking water purposes should be avoided. High boron contents of sewage effluent indicate a risk for crops sensitive to boron.*The accumulation of heavy metals and phosphorus in the soil adversely affects the soil system.*Pretreatment of sewage effluent in Gabal el Asfar should be improved to limit the pollution of the aquifer. Industrial discharge in sewage effluent should be avoided.*Groundwater recharged by sewage effluent is mainly collected by drains in or at the borders of the area, so spreading of pollutants out of the area is largely controlled.
