N2  - The long term (e.g., 15 to more than 50 years) effects of  primary treated wastewater (PTWW) irrigation on soil properties and  heavy metal concentrations at Abou-Rawash farm, Giza Governorate,  and its surrounding agricultural land were investigated. Soil profiles  represented five definite locations (I, II, III, IV and V) including  different landscapes features from either Abou-Rawash farm (I, II  and III) or its surrounding area (IV, V). In addition, control soil  profile (VI) was investigated from crop cultivated area irrigated with  Nile freshwater (FW). At each location, soil samples were collected  from subsequent layers (0-20, 20-40, 40-60 and 60-80 cm) for  determination of various physico-chemical parameters. The total and  DTPA extractable contents of heavy metals (Ba, Cd, Cr, Co, Cu, Fe, Pb, Mn, Ni, Zn) were also determined. The X-ray diffraction (XRD)  analysis was undertaken to qualitatively investigate the composition  of the soil samples mineralogy.  The analysis of PTWW indicated that most of the  physicochemical parameters and heavy metals concentrations were  within the limits proposed by national and international guidelines for  irrigation water. The bacteriological counts such as total and fecal  coliforms indicated that the wastewater was not suitable for irrigation  purposes and denotes the potential public health hazards.Soil analysis revealed that the dominant fractions were the sand  across the six locations investigated and soil bulk density was  redistributed under PTWW irrigation which deceased the bulk density values and thus increased soil total porosity. Furthermore,  measurements revealed that pH and CaCO₃ values were high in  PTWW irrigated soils compared to Nile FW irrigated soils
