“…Except for NO3-N, higher values were observed in the SW than the GW, in agreement with other studies (Cirelli et al, 2012;Lopez et al, 2010). Compared to GW, SW was characterised by higher NH4-N and PO4-P, which are strongly related to soil fertility and plant growth, as well as by higher organic matter content (as indicated by the TSS, COD and BOD5), Na + and ECw.…”

“…Our results are in agreement with other recent studies that have shown low impact for the microbial contamination of tomato crops irrigated by treated secondary wastewaters (Cirelli et al, 2012;Christou et Gatta et al, 2014). This will be due to several factors, such as: the drip irrigation system and mulching system adopted, and the effects of UV radiation exposure on the fruit and leaf surfaces.…”

This study was designed to determine the qualitative and microbiological impact of two different sources of irrigation water on tomato fruit: groundwater (GW), as the control, and treated agro-industrial wastewater (SW). The mean tomato fruit quality parameters of dry matter, weight, diameter, colour index, pH, soluble solids content, titratable acidity, Ca 2+ and Na + content were not significantly affected by the different water treatments. Conversely, NO3 -contents was significantly higher with GW use, than with SW (2.21 vs 1.62 mg 100 g -1 , respectively; P≤0.05). The microbial quality of the tomato fruit was not significantly different across the GW and SW treatments, with no Salmonella spp. isolated from any of the fruit, and the faecal indicators always below 10 CFU g -1 . These data show that agro-industrial treated wastewater can be used for irrigation for industrial tomato production once the long-term effects on the agroecosystem have been defined.

“…For fruit trees or vegetables cultivated on vines and not in direct contact with irrigation water, the risks of transmission may be lower than for vegetables which grow in direct contact with the soil and irrigation wastewater (Cirelli et al, 2012;Melloul et al, 2001). In addition, methods that increase the probability of direct contact between waste-water and edible part of plants (e.g., furrow irrigation) seem to promote greater contamination of plants than subsurface drip irrigation (Song et al, 2006a).…”

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.

“…Aynı şekilde, tuz içeriği yüksek olan asit veya nötr sular da toprakların pH'sını düşürdüğünden bu elementleri zehirli duruma geçirebilirler (Karataş ve ark., 2005). Ayrıca sulama suyunun, pH'sının yüksek olması ile birlikte yüksek sıcaklık ve sertliğe maruz kalan boru hatlarında emitörlerin tıkanmasına ve akış hızının düşmesine neden olduğu daha önceki araştırmalarla teyit edilmiştir (Cirelli et al, 2012). …”

Bu çalışmada, evsel nitelikli atıksu arıtma tesisi çıkış sularının alıcı ortama deşarj edilmesi yerine tarımsal amaç için yeniden kullanılabilirliği araştırılmıştır. Çalışmada materyal olarak bir işletme çalışanlarının evsel amaçlı kullanımları sonucu oluşan atıksuları için projelendirilen ve ardışık kesikli reaktör prensibi ile çalışan biyolojik paket arıtma tesisi çıkış suları kullanılmıştır. Biyolojik arıtma işleminden geçirilen evsel nitelikli atıksuyun tarımsal sulamaya uygunluğu Su Kirliliği Kontrolü Yönetmeliği ve Atıksu Arıtma Tesisi Teknik Usuller Tebliği kapsamında değerlendirilmiştir. Arıtma tesisinden çıkan atıksuların analiz sonuçlarına göre Biyokimyasal Oksijen İhtiyacı (BOİ), Kimyasal Oksijen İhtiyacı (KOİ), Askıda Katı Madde (AKM) parametrelerinde sırasıyla %98, %97 ve %95 giderim verimleri elde edilmiş olup, Su Kirliliği Kontrolü Yönetmeliği Tablo 21 kapsamında değerlendirildiğinde alıcı ortam deşarj standartlarının altına düştüğü belirlenmiştir. Arıtma tesisi çıkış suları analiz sonuçları Atıksu Arıtma Tesisleri Teknik Usuller Tebliği Ek7 kapsamında değerlendirildiğinde de bulanıklık, elektriksel iletkenlik ve sodyum parametrelerinin standartları sağlamadığı ve bu nedenle bu suların tarımsal sulamada kullanımının uygun olmadığı belirlenmiştir.
