“…Evaluations of the efficiency of sewage treatment systems in several Brazilian states confirm this range, with average values of 25 to 150 mg L -1 (GONÇALVES, et al, 2015;QUEIROZ;QUEIROZ;ARAGÃO, 2015). Regarding the agricultural application, effluents with concentrations above 65 mg L -1 were applied as fertigation to crops in the semiarid region and did not interfere with their growth (RIBEIRO et al, 2012;SALGADO et al, 2018).…”

“…Several studies present non-quantifiable values of metals. Andrade Filho et al (2013), Oliveira et al (2014), Queiroz, Queiroz andAragão (2015), and Salgado et al (2018) evaluated copper, iron, manganese, and zinc contents in sewages used for irrigation in the Brazilian semiarid region and found 0.02 to 0.45 mg L -1 (Cu), 0.18 to 2.20 mg L -1 (Fe), 0.07 to 0.15 mg L -1 (Mn), and 0.05 to 1.25 mg L -1 (Zn), with no effect on the development of the crops.…”

Wastewater Use in Agriculture: Analytical Limits of Sewage for Impact Control in Brazil

Water deficit is a current problem of global relevance. This is a problem in Brazil, especially in the Semiarid region, which undergoes severe droughts for much of the year. This requires the search for alternatives, such as the planned wastewater use, which is a successful alternative in developed countries that is applied for various purposes, including agriculture. However, despite the increasing growth of agriculture in Brazil, there are no established control and monitoring policies to minimize its impacts on the environment and human health. The country does not have specific legislation that defines wastewater quality parameters for domestic sewage. The objective of this work was to compile international guidelines and legislations that address this issue and compare them with the national normative resolutions for quality of wastewater and its different uses. The most relevant and locally applicable parameters described in these documents were listed, and the reference limits were defined by comparing them with those found in the scientific literature applied to the Brazilian context. This compilation represents the first step towards the incorporation of regulations for water reuse, having the Brazilian Semiarid region as a first test field, but with expandable application to different regions of the country.

“…Several researches have pointed out the possibility of irrigation of several plant species with poor quality water, being a widely studied practice and recommended by several researchers and water managers. From a nutritional point of view, studies have shown positive effects of irrigation with high salinity water, such as sewage, on the production and productivity of vegetables, proving the fertilizing effect of wastewater in numerous studies and in various cultures such as sunflower (Santos Júnior et al, 2014;Oliveira et al, 2017), pepper (Silva et al, 2019), melon (Costa et al, 2014), corn (Malafaia et al, 2016), tomato (Jorge et al ., 2017) and watermelon (Salgado et al, 2018).…”

Poor quality water, such as sewage, has become an alternative to reduce the consumption of good quality water by irrigation, especially in arid and semi-arid regions; however, water rich in salts can be harmful to agricultural systems. This research evaluated the impacts of salinity of waters of different qualities on the development of the sunflower culture and on the soil. The research was developed in the area of the Environmental Studies Team (EEA/UEFS), and the experimental design used was completely randomized, consisting of four treatments: rain water (0.20 dS m-1), well water (1.50 dS m-1), cesspool effluent (3.50 dS m-1) and brackish water (5.00 dS m-1), with the irrigation manually done and the blade calculated based on daily evapotranspiration. Irrigation with effluent promoted a better development of the sunflower crop, and the increase in the salinity of the irrigation water in the other treatments promoted a decrease in the total fresh and dry phytomasses, plant height, stem diameter, number of leaves, leaf area, internal and external diameters of the capitula and in the consumption and efficiency of water use. The use of rainwater, well water and cesspool effluent proved to be suitable for irrigation of the sunflower crop; however, the latter sodified the soil, which would already be recommended for the application of treatments for soil recovery.

“…Maize cultivation in the Brazilian semi-arid region stands out for its economic importance in family farming, with a high contrast in yield due mainly to climatic conditions, irrigation and fertilization practices [1,2]. Due to water scarcity in the region, the use of wastewater for irrigation is a promising alternative for reducing the consumption of higher-quality water and hence reducing environmental How to cite: Almeida, T.A.B., M ontenegro, A.A.A., de Carvalho, A.A. and Tabosa, J.N., Soil and crop spatial variability in maize irrigated with domestic effluent.…”

Wastewater use in agriculture is a high-potential alternative for coping with water scarcity. The present study aimed to evaluate the impact of using wastewater and sewage sludge on soil attributes in an irrigated maize plantation in the Brazilian northeastern semi-arid region, at an experimental reuse unit. Two experimental plots were installed with the following treatments: wastewater and sludge, and irrigation with wastewater only. The presence of sludge reduced the salt content and promoted an increase in the soil organic matter content, reducing the salinization risk. Biometric parameters showed no spatial dependence. On the other hand, soil moisture, electrical conductivity, sand content, clay content and sodium and potassium contents showed strong spatial dependence for the treatment with sludge application.
