Environmental quality of peri-urban and rural water resources in an agricultural municipality in Southern Brazil

Assessment the quality of water resources by indicators and bioindicators associating with the of land use and occupation activities can indicate whether an environment is affected by anthropic actions. This study aimed to evaluate the quality of a water resource using chemical, physical, microbiological, cytotoxicity and genotoxicity parameters. Water samples were collected at five sites of the Raiz River, Condor/Rio Grande do Sul/Brazil and analyzed by specific protocols. Except for the pH at the source, which had a value below the minimum established limit, the thermotolerant coliform in an amount higher in four sites, and total coliform present in all sites, the results showed that all the parameters are agree with the current Brazilian legislation. Allium cepa test showed variation in the mitotic index and the presence of cell changes. The study indicated that the activities in the surroundings of the water resource influence in the analyzed parameters.
