Resumo: | In Brazil, mainly in the semiarid region, a major challenge is to promote the water supply to households in rural areas. Groundwater is identified as a viable alternative to ensure the access of rural communities in the northeast to water from public investment in drilling wells. However, these water sources in most cases have use restrictions for human consumption, because they present problems of salinity. The technology of reverse osmosis has been widely used for treatment of brackish water, with successful experiences in most locations where units have been deployed in water treatment by desalination. Many rural communities in Mossoró, RN, are supplied with water from the aquifer Jandaíra, high salt concentration, which is treated in desalination plants, allowing its use for human consumption. In these communities, the reject brine of the process of desalination is not receiving any treatment or proper disposal, being dumped straight into the ground and, when used in irrigation of crops there are no scientific-technical reasons for their use, causing problems of soil salinization. Due to the impacts caused by the use of brackish or reject brine for irrigation in the soil, to enable their use should always adopt some special practices of water management and soil for salinity control. As the majority of crops grown in the region classified as sensitive to moderately sensitive to salinity, there is the need to better characterize these waters, to establish the appropriate management of plants, soil and irrigation systems. As the majority of crops grown in the region are classified as sensitive to moderately sensitive to salinity, there is the need to better characterize these waters, to establish the appropriate management of plants, soil and irrigation systems. Thus, this study aimed to evaluate the quality of water for irrigation in rural communities of Mossoró, supplied with brackish water from tube wells equipped with desalination, providing this information as a tool to aid the proper management and use of these waters irrigation. 30 rural communities were selected to perform the collection of samples of water from the waste generated in the desalination, purified and in its natural form (brackish water of the well). In the collected samples were determined at electric conductivity (ECw), pH and concentrations of Na+, Ca2+, K+, Cl-, HCO3 - e CO3 2-, in addition, the sodium adsorption ratio (SAR). The Analyses of water samples were interpreted as to risk of salinity, sodicity, toxicity of ions and other quality parameters. The results show that water of the wells rural communities studied, have restrictions to their use in agriculture, as to risks of salinity and sodicity of the soil, especially the waters of the communities: São Romão, Boa Fé and Pau Branco. the reject brine of the desalination have high concentrations of salts, especially in communities of Boa Fé and Puxa Boi, compromising their use for irrigation, and, the desalinated water, although they have low concentrations of salts have restrictions on the problems of infiltration into the soil, if by chance, are employed in irrigation. |

As águas subterrâneas são apontadas como uma alternativa viável para garantir o acesso das comunidades rurais do nordeste à água, a partir de investimentos públicos na perfuração de poços tubulares. Entretanto, essas fontes hídricas apresentam na maioria dos casos restrições de uso para dessedentamento humano, por apresentarem problemas de salinidade.A tecnologia da osmose reversa tem sido amplamente utilizada para o tratamento da água salobra, com experiências de êxito na maioria das localidades aonde têm sido implantadas as unidades de tratamento de água por dessalinização. Muitas comunidades rurais de Mossoró, RN, são abastecidas com água proveniente do aquífero Jandaíra, de elevada concentração de sais, a qual é tratada em dessalinizadores, possibilitando sua utilização para consumo humano. Nessas comunidades, o rejeito do processo da dessalinização não está recebendo qualquer tratamento ou destinação adequada, sendo despejado diretamente no solo e, quando utilizados na irrigação de culturas não há qualquer fundamentação técnico-científica para o seu uso, causando problemas de salinização nos solos. Devido aos impactos causados pelo uso de águas salobras ou de rejeito salino na irrigação no solo, para viabilizar a sua utilização deve-se sempre adotar algumas práticas especiais de manejo da água e do solo para o controle da salinidade. Sendo a maioria das culturas exploradas na região classificadas como sensíveis a moderadamente sensíveis à salinidade, surge a necessidade de melhor caracterizar essas águas, para se estabelecer o manejo adequado das plantas, solo e sistemas de irrigação. Assim, o presente trabalho objetivou avaliar a qualidade da água para fins de irrigação de comunidades rurais de Mossoró, abastecidas com águas salobras provenientes de poços tubulares, dotados de dessalinizadores, fornecendo estas informações como uma ferramenta de auxílio para o manejo adequado da utilização destas águas na irrigação. Foram selecionadas 30 comunidades rurais para realização das coletas de amostras das águas do rejeito gerado na dessalinização, purificadas e na sua forma natural (água salobra de poço). Nas amostras coletadas foram determinadas a condutividade elétrica da água (CEa), o pH e concentrações de Na+, Ca2+, K+, Cl-, HCO3 - e CO3 2-; além disso, a razão de adsorção de sódio (RAS). As análises das amostras de água foram interpretadas quanto aos riscos de salinidade, sodicidade, toxidade de íons e outros parâmetros de qualidade. Os resultados mostram que as águas dos poços das comunidades rurais estudadas possuem restrições para a sua utilização na agricultura, quanto aos riscos de salinização e sodificação do solo, principalmente as águas das comunidades: São Romão; Boa Fé e Pau Branco; as águas de rejeito da dessalinização possuem elevadas concentrações de sais, principalmente nas comunidades de Boa Fé e Puxa Boi, comprometendo a sua utilização para a irrigação e as águas dessalinizadas, embora possuírem baixos teores de sais têm restrições quanto a problemas de infiltração no solo, caso venham a ser empregadas para irrigação.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfhttp://repositorio.ufersa.edu.br/retrieve/970/ChristianoRC_DISSERT.pdf.jpgporUniversidade Federal Rural do Semi-ÁridoPrograma de Pós-Graduação em Irrigação e DrenagemUFERSABRCentro de Ciências Agrárias - CCACC-BY-SAinfo:eu-repo/semantics/openAccessSalinityBrackish watersIrrigationSalinidadeÁguas salobrasIrrigaçãoCNPQ::CIENCIAS AGRARIAS::AGRONOMIAAvaliação da qualidade da água proveniente de estações de tratamento de água salobra na zona rural do município de Mossoró, RNEvaluation of water quality from treatment plants of brackish water in rural zone of the Mossoró, RNinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisreponame:Biblioteca Digital de Teses e Dissertações da UFERSAinstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSATEXTChristianoRC_DISSERT.pdf.txtChristianoRC_DISSERT.pdf.txtExtracted texttext/plain150541https://repositorio.ufersa.edu.br//bitstream/tede/483/3/ChristianoRC_DISSERT.pdf.txtf12ccae0bd9deea194bdc5103af0e01dMD53ORIGINALChristianoRC_DISSERT.pdfapplication/pdf985774https://repositorio.ufersa.edu.br//bitstream/tede/483/1/ChristianoRC_DISSERT.pdf16a5bb519ba17167ab91e67bf421f7f6MD51THUMBNAILChristianoRC_DISSERT.pdf.jpgChristianoRC_DISSERT.pdf.jpgGenerated Thumbnailimage/jpeg2760https://repositorio.ufersa.edu.br//bitstream/tede/483/2/ChristianoRC_DISSERT.pdf.jpg7cd355160a4e731d8cb5815b0a29c4ebMD52tede/4832022-07-04 12:05:38.31oai:repositorio.ufersa.edu.br:tede/483Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufersa.edu.br/PUBhttp://bdtd.ufersa.edu.br/oai/requestdirecaosisbi@ufersa.edu.br|| direcaosisbi@ufersa.edu.bropendoar:2022-07-04T15:05:38Biblioteca Digital de Teses e Dissertações da UFERSA - Universidade Federal Rural do Semi-Árido (UFERSA)false |
