“…Sources of waste water are domestic sewage effluent (municipal wastewater), agricultural effluents, industrial effluents, and storm water (Kunhikrishnan et al, 2012). Irrigation with sewage effluent have advantages such as providing economic and effective alternative sources of water (Ali et al, 2013) and saving fertilizer costs due to nutrients contents in water (Minhas et al, 2015). Different implications on soil properties were reported due to irrigation with sewage water (Lado and Ben-Hur, 2009).…”

“…Prolonged irrigation of sewage water could be a potential environmental risk (Mapanda et al, 2005). It releases organic contaminants into soil and water (Wang et al, 2015), leaches metals into underlying aquifers, affecting the quality of drinking water (Lottermoser, 2012) and cause health risks due to pathogenic infestation (Ahmad et al, 2011;Chopra and Pathak, 2012;Minhas et al, 2015). Many farmers in developing countries irrigate crops using raw urban and industrial effluents.…”

Sewage irrigation may provide an alternative resource due to scarcity of fresh water in Egypt, thus such a practice should be evaluated. A number of 36 pairs of soil samples were collected; each pair consisted of one sample irrigated with fresh water and another irrigated with sewage water from two different sites in Al-Qalyubia Governorate, Egypt. Sewage water-irrigated soils showed higher pH, EC, N, P, K, Fe Mn, Zn, Cd, Pb and Ni than fresh water-irrigated soils. Positive changes in soil properties occurred with sewage irrigation. Bulk density decreased field capacity, organic carbon and nutrients increased by sewage water irrigation. There was build-upin Cd, Pb, Ni and Zn. Single pollution index (SPI) and pollution load index (PLI) indicated no pollution in fresh water irrigated soils as both parameters did not exceed 1.0. Sewage irrigated soils were moderately polluted. The contamination factor (CF) revealed aconsidered contamination with Pb and high for Cd, Ni and Zn. The contamination degree was very high. Food crops cultivation in such soils should be practiced under precautions with a change in the cropping pattern.

“…Thus, wastewater used as an alternative source (6)(7)(8). In addition, nutrients exist in wastewater help to save fertilizer costs (9)(10)(11)(12). The establishment of greenbelts around cities by forest trees irrigated by wastewater serves to revive the ecological balance and improves environmental conditions by selftreatment of wastewater through the practice of forest irrigation (13).…”

Background: After suffering from an acute problem of excess water for a long time, the Oasis of Ouargla benefited from an aerated lagoon treatment plant, producing biologically treated domestic effluents. The aim of this study was to examine the feasibility of reusing this effluent for watering plants. The experiment was conducted in the Ouargla WWTP, which is located in the region of Said Otba (northeast of Ouargla), north of the national road NR 49. Methods: The study area was selected based on the originality of the study and availability of water. The plants used were Acacia farnesiana and Leucaena leucocephala. The selection of Leucaena was based on the following criteria: It is used as a windbreak, it is very tolerant to drought, and it is used as a fodder to maintain soil fertility. And, Acacia was selected because it is used as a fodder, protects the soil against erosion, and to fix nitrogen. The watering of these plants is done jointly by treated wastewater from the WWTP and well water (WW), of which the latter was used as a control. Sampling and analysis of the irrigation water were performed according to the experimental protocol. To show the growth rate of the two plants studied, biometric measurements were taken weekly for 25 weeks. Results: The physicochemical analyses show that the treated wastewater is of poor quality belonging to the last class of Riverside’s C5-S4, with an excessive salinity (EC) of 13.51 dS/m and an Sodium adsorption ratio (SAR) of 12.61 against EC of 2.49 dS/m and 2.13 for the WW. At the end of the experiment, it was found that irrigation with purified wastewater (PWW) gave less growth compared to that with WW. Statistical analyses of the biometric measurements confirmed that there is a highly significant difference at P<0.05. Conclusion: The reuse of WWTP effluent gives less interesting results but is still possible. It is recommended to choose Salt-tolerant crops, as well as the dilution of these waters by the addition of less salty waters.

“…in soils and groundwater (Yadav et al, 2002;Rattan et al, 2005;Qadir et al, 2007Qadir et al, , 2010Minhas and Lal, 2010;Murtaza et al, 2010). However, this wastewater based irrigation has a number of limitations, includes the pollution of groundwater, built up of heavy metals, pesticides and other pollutants in the soil and the creation of habitat for harmful microorganisms which pose threat to farmer's/consumer's health and the environment through diseases from pathogens and vectors (Mapanda et al, 2005;Murtaza et al, 2010;Qadir et al, 2010 andMinhas et al, 2015). Several studies confirmed the presence of heavy metals (Mogen Henze et al, 2002;Cao and Hu, 2004;Mapanda et al, 2005;Nan et al, 2002;Huang et al, 2017;Yan et al, 2018) and their potential bioaccumulation, when wastewater is used for irrigation.…”

<p>The objective of the study is to determine accumulation and translocation of heavy metals from soil to paddy straw irrigated with urban sewage wastewater in peri-urban region of Girudhumal subbasin area in Madurai. The soil samples were collected in seven locations irrigated with treated and untreated wastewater and analyzed for physical properties like pH, EC, bulk density, soil type, major (N,P,K) and micronutrients (Fe, Mn, Cu, Zn) and heavy metals Ni, Cd, Pb. SEM analysis showed that soil structure is significantly influenced by wastewater irrigation. It confirms that the wastewater irrigation disturbs soil structure and affecting the plant growth in long run.  Pb content was higher than the prescribed safe limits in S5 and S6 location, similarly, Ni also was higher than the safe limit in all the locations. Pollution Load Index values are in the range of 0.08-0.56 for all sites, and it indicated that chance of heavy metal contamination is less. The EF values show moderate enrichment to Ni and Zn, Significant enrichment for Cd and Cu, Extremely high for Pb and deficiency for Mn. All these results confirmed that there is no immediate risk of heavy metal pollution, however with respect to Pb and Ni the plant tissues are showing higher values. The transfer factor for heavy metals from soil to paddy straw is less than 0.5 for Cd and for others is more than 0.5 indicated greater chances for heavy metal contamination.</p>
