“…There are different attributes of wastewater that may contribute to reduction in infiltration rates and hydraulic conductivity when wastewater irrigation is applied (Magesan et al 1999). Some of reported mechanisms by researchers are: blockage of the inter-soil spaces by suspended material such as colloidal clay and algal cell particles (Berend 1967, Bouwer andChaney 1974), formation of a biological mat or crust (Kristiansen 1981, Balks et al 1997, biological clogging including microbial extracellular (Thomas et al 1966, McAuliffe et al 1982, collapse of soil structure due to organic matter dissolution (Nevo and Mitchell 1967, Vandevivere and Baveye 1992, Lieffering and McLay 1996. Infiltration rate and hydraulic conductivity may also decrease through physical blocking of soil pores as a result of high loads of suspended solids during land application of wastewater (Magesan et al 2000).…”

This study was carried out to investigate the effect of treated wastewater on soil chemical and physical properties. Field experiment was conducted in Borkhar region in Isfahan province in central Iran with two water treatments of wastewater and groundwater under sprinkler and surface irrigation systems for three crops of sugar beet, corn and sunflower. Soil samples were collected to 120 cm depth to determine concentration of lead (Pb), manganese (Mn), iron (Fe), cadmium (Cd), nickel (Ni), cobalt (Co), copper (Cu) and zinc (Zn). Irrigation systems had no significant effect on extractable heavy metals in soil. The accumulation of Pb, Mn, Ni and Co in the soil increased significantly in the wastewater treatment as compared to the groundwater treatment. The accumulation of Pb, Mn, Ni, Co, Cu and Zn decreases with the soil depth. Treated wastewater showed no effect on the increase of Fe, Cd, Ni, Cu and Zn during growing season. The irrigation system had a significant effect on infiltration rate, bulk density and total porosity. Under sprinkler irrigation system the infiltration rate increased significantly.

Surface irrigation of pasture with treated sewage effiuent at Templeton, Christchurch for up to 16 years, had little effect on the heavy metal composition of the soil or pasture. Slightlv higher levels of O.IN HC1-extractable Zn, Cu, Co, and Mn in the effiuent-treated soil did not increase levels of these elements in the pasture, and did not increase the Cd/Zn ratio. The ilb:ience of any marked changes in heavy metal content is attributed to the low levels of these elements in the raw sewage effiuent, which is of domestic origin. It is concluded that at the present effiuent application rate (840 mm/year) the scheme, without sludge disposal, has an essentially indefinite life span, in terms of heavy metal accumulation. If land application of the sludge is introduced, it would take at least 200 years for heavy metals to reach the recommended limit of 5% of the soil cation exchange capacity.

“…The use of sewage effluents for agricultural irrigation is an old and popular practice in agriculture (Feigin et al, 1984). Irrigation with wastewater has been used for three purposes: i. complementary treatment method for wastewater (Bouwer & Chaney, 1974); ii. use of marginal water as an available water source for agriculture (Al-Jaloud et al, 1995; Tanji, 1997) -a sector demanding ~ 70% of the consumptive water use.…”
