Resumo: Water is a basic natural resource for the maintenance of life and is indispensable in all human activities. Since it is a limited natural resource, concern on the conservation of its quality is high, coupled with efficacious mechanisms that may diminish negative environmental impacts. Current analysis applies the Water Quality Index (WQI) for hydraulic barriers in the urban stretch of Mossoró RN Brazil and verifies the water body conditions according to usage classes, with special reference to predominant factors and previous classification of the water body. Collection of water for analysis of WQI parameters was undertaken in July 2010 in three barriers within the urban stretch and geo-referenced for the indication of critical sites. Possible exploratory activities linked to the contamination of the water body were listed. An evaluation of rates was undertaken and compared with current legislation guidelines. According to CONAMA n. 357/2005, results showed that analyses during the dry period referred to the salinity of the water body when related to preponderant usage indexes, or Class 1. Total phosphorus failed to comply with rates when parameters were analyzed one by one and compared to standards established by CONAMA n. 357/2005. Water was of good quality at the first barrier and fair in the others from the entrance of the city and downstream, due to the great load of home effluents, agro-industrial wastes and surface runoff.

Sendo um recurso natural limitado, a preocupação com a conservação da qualidade da água tornou-se crescente, concomitante a procura de mecanismos eficazes, capazes de mitigar os impactos ambientais negativos. O presente trabalho tem como objetivo aplicar o Índice de Qualidade de Água (IQA) aos barramentos hidráulicos situados no trecho urbano do município de Mossoró-RN, sendo, posteriormente, feita a verificação da condição do corpo hídrico de acordo com as classes de uso, ressaltando os preponderantes, além da classificação prévia do corpo hídrico. As coletas de água para análise dos parâmetros referentes ao IQA foram realizadas no mês de julho de 2010, distribuídas em três barramentos situados no trecho urbano, sendo georreferenciadas, subsidiando a indicação dos pontos críticos. Foram elencadas as possíveis atividades exploratórias contribuintes com a contaminação do corpo hídrico. Por fim realizada a avaliação individual dos valores obtidos comparados com as diretrizes das legislações vigentes. Com os resultados obtidos, baseado na resolução CONAMA nº 357/2005, verificou-se que as análises para o período de estiagem, evidenciam a condição do corpo hídrico quanto a salinidade como água salobra, em relação aos usos preponderantes, Classe 1. Entretanto, quando analisados individualmente os parâmetros e comparados aos padrões estabelecidos pela resolução CONAMA nº 357/2005, constata-se que o fósforo total apresentou valores em desacordo. A partir da entrada da cidade e à jusante desta, em função da grande carga de efluentes domésticos e despejos agroindustriais, além do escoamento superficial, a água apresenta-se com qualidade boa no primeiro barramento e regular nos demais.UEL2013-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1277410.5433/1679-0359.2013v34n6Supl1p3443Semina: Ciências Agrárias; Vol. 34 No. 6Supl1 (2013); 3443-3454Semina: Ciências Agrárias; v. 34 n. 6Supl1 (2013); 3443-34541679-03591676-546Xreponame:Semina.
