“…The results for Fe 2+ and Zn 2+ are in accordance with those obtained by Xu et al (2010) in short duration (three years) wastewater irrigation, suggesting that these wastewater metal concentrations are not high enough to cause environmental impacts in experiments of such duration.…”

“…In general terms, it was observed that all studied cationic micronutrients present a low soil mobility and tend to accumulate in the upper layers. According to some other studies (Rusan et al, 2007;Kiziloglu et al, 2008;Xu et al, 2010), the mobility of these elements to deeper layers in wastewater irrigated soils is not common, because it is closely related to the organic matter distribution in the soil profile. conclusIons 1.…”

“…The magnitude of changes in soil chemical attributes depends mainly on local conditions, such as soil type, depth range, quality and quantity of used wastewaster in the system, and the kind of grown plant species (Corwin & Bradford, 2008;Kiziloglu et al, 2008;Xu et al, 2010;Liang et al, 2010;Leal et al, 2010). These changes may result in significant impacts in the soil quality (Fonseca et al, 2005;Herpin et al, 2007), or may not (Varallo et al, 2010;Duan et al, 2010).…”

Agricultural use of wastewater is an alternative to increase water availability, especially in semiarid regions. However, it may cause undesirable chemical changes in the soil. The aim of this study was to evaluate the influence of wastewater irrigation and castor bean (Ricinus communis L.) cultivation on the chemical attributes of a Fluvic Neosol. The experimental design was in a randomized block, in split-plot scheme, where the main plots were represented by the treatments of irrigation water and castor bean cultivation, and the subplots were the soil layers, with three replications. The treatments were T1 -wastewater irrigation + castor bean cultivation ; T2 -mixture of supply water and wastewater (1:1 ratio) + castor bean cultivation; T3 -supply water irrigation + castor bean cultivation ; and T4 -wastewater application, without castor bean cultivation. The depths of soil layers were 0-10, 10-20, 20-30, 30-40, and 40-50 cm. At the end of study, the content of phosphorus, calcium, potassium, and organic matter increased mainly in the upper layers, and sodium increased in the deeper layers in the wastewater treatments, in comparison to the supply water irrigation. In T4, the disposal of wastewater increased the concentration of magnesium. The pH values, iron and zinc concentration did not statistically differ in the treatments.

“…Some studies reporting metal accumulation in soil after irrigation with wastewater related this accumulation with the reduction of alkaline phosphatase activity and soil ATP content, the suppression of the sporulation and diversity alteration of arbuscular mycorrhizal fungi and the emergence of metal resistance in bacteria (Faryal et al, 2007;Ortega-Larrocea et al, 2001;Yim and Tam, 1999). Leaching is an-other possible consequence of metal accumulation in soils, mainly after long periods (~20 years) of irrigation with wastewater (Xu et al, 2010). Moreover, accumulated metals may interact synergistically with other contaminants, such as antibiotics, exacerbating their potential effects (Kong et al, 2006;Peltier et al, 2010).…”

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in soil. The first may affect soil productivity and fertility; the second may pose serious risks to the human and environmental health. The sustainable wastewater reuse in agriculture should prevent both types of effects, requiring a holistic and integrated risk assessment. In this article we critically review possible effects of irrigation with treated wastewater, with special emphasis on soil microbiota. The maintenance of a rich and diversified autochthonous soil microbiota and the use of treated wastewater with minimal levels of potential soil contaminants are proposed as sine qua non conditions to achieve a sustainable wastewater reuse for irrigation.

“…Tarchouna et al ( 2010 ) showed that despite the very sandy texture of irrigated (with treated wastewater) soils studied, both saturated and unsaturated hydraulic conductivity exhibited a signifi cant diminution in the irrigated soil compared to the reference one in Mediterranean countries. In the U.S.A., Xu et al ( 2010 ) argued that the increase of available soil profi le heavy metals was not hazardous due to the leaching of metals, owing to the light soil texture and the low organic matter content of the plots studied. In regard to soil conditions, neither the soil nitrogen nor carbon was signifi cantly impacted by wastewater irrigation (Hunt et al 2011 ).…”

Global Experiences on Wastewater Irrigation: Challenges and Prospects

The need for irrigated agriculture is growing day by day and the largest water withdrawals from renewable water resources are for irrigation. In addition, the available water resources are decreasing and we need to use non-conventional water resources for irrigation due to looming water crisis (Raschid-Sally and Jayakody, Drivers and characteristics of wastewater agriculture in developing countries: results from a global assessment. International Water Management Institute, Colombo, 35p, (IWMI Research Report 127), 2008). However, the volume of treating and using wastewater is limited due to the lack of adequate data and knowledge and/or negative effects of improper wastewater management (i.e. use of untreated wastewater). A comprehensive evaluation of what has been done is necessary in order to explore wastewater irrigation and to avoid trial-and-error policies. Although a study of wastewater irrigation from crops, soil, groundwater, health, irrigation equipments, modern technologies, and other environmental aspects is useful, management studies in comparison with other aspects can help lead to more reliable and more extensive fi ndings and fi nally a better decision on using wastewater for irrigation. The chapter presents challenges and prospects that may help decision making for the use of wastewater in irrigation.
