“…Tam (1998) did not observe changes in phosphatase or dehydrogenase activities in mangrove soils irrigated with wastewater. Kayikcioglu (2012) reported a decrease of the activities of enzymes aryl sulfatase, dehydrogenase, urease, alkaline phosphatase and β-glucosidase in wastewater irrigated agricultural soil. The inhibition of microbial growth or activity after wastewater irrigation is probably explained by the fact that besides nutrients also contaminants, such as heavy metals, are being supplied (Kayikcioglu, 2012;Yim and Tam, 1999).…”

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.

“…Moreover, the valuable nutrients in the river water could develop crop production, promote root growth and increase amount of plant residues [16], thereby increasing the SOC pools. However, such increase of SOC under treated wastewater irrigation was not observed in some other researches [3]. This was mainly because of the low concentration of organic matter in the treated wastewater and short period of experimental time in their studies.…”

“…Therefore, wastewater is recommended for use in agriculture after treated and under controlled conditions to minimize hazards from toxic contaminants. The effects of irrigation with treated wastewater on soil quality has been intensively studied in recent years [2,3], but mainly focused on the direct use of wastewater for irrigating crops. In fact, most of the treated wastewater from wastewater treatment plant is discharged into rivers that supply water for agriculture.…”

Abstract-In arid and semi-arid regions in China, a large amount of treated wastewater is discharged into rivers that supply water for agriculture. Treated wastewater contains not only valuable nutrients, but also toxic contaminants that might affect soil quality. This study investigated how long-term irrigation with water from a wastewater receiving river affected soil chemical and microbiological properties in Hebei Province, China. Soil samples were collected from three river water irrigated fields adjacent to Wangyang River, and three groundwater irrigated fields far from the river. The results showed that irrigation with river water for more than 20 years had significantly increased dissolved organic C, microbial biomass C and permanganate oxidizable C contents, and β-glucosidase, urease, alkaline phosphatase, arylsulphatase and dehydrogenase activities in the surface soil, reflecting a stimulated microbial activity in river water irrigated soils. Long-term irrigation with river water has also resulted in accumulation of Hg, Cd, As, Pb, Cu, Cr and Zn in the soil, and may pose potential risk to soil quality and food safety. We conclude that although the river water irrigation has beneficial effects on soil microbiological characteristics, a controlled irrigation management based on periodic monitoring of soil quality parameters is needed to ensure its safe and long-term use in agriculture.

“…In Tunisia, Cr and Cu have affi nities both to clay and humic substance quantities. Kayikcioglu ( 2012 ) detected a decrease in the microbial activities in soil, depending on irrigation with wastewater in Mediterranean countries. Adrover et al ( 2012 ) claimed that after more than 20 years of treated wastewater irrigation, no negative changes have been observed in the evaluated soil properties of the Island of Mallorca in Spain, with the exception of an increase in the soil pH caused by greater sodium supply.…”

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.
