| Description | Two sewage farms existing near Cairo since 1915 (Gabel el Aswar) and 1936 (Abo Rawash) respectively used flooding ponds and gravity irrigation to grow crops and citrus. As industry established in the catchments of the sewage farms, heavy metals derived from industry appeared in the sewage. The soil in the sewage farm with flooding ponds has a higher content of heavy metals than the other but at both stations only two are higher. The heavy metal content in the groundwater exceeds the limit for chromium due to ancient leather factories. Where the groundwater is high, nitrate is detectable in concentrations over the limit of WHO. As the groundwater from the Tertiary aquifer has higher salinity mineralized (over 2000 μS/cm) dilution takes place. The unintentional artificial recharge with the sewage lowers the electrical conductivity and makes a reuse of the groundwater for irrigation possible. With the treated sewage of Cairo's new plant an additional area of 1300 $km^{2}$ could be irrigated decreasing the mineral content of the groundwater and enabling its reuse.
