Impact on water quality in streams and rivers has intensified during the last decades and the contamination of natural water has occurred diffusely and at specific sites. Current analysis evaluates the impact of small family agro-industries on the water quality of streams in the Quarta Colônia de Imigrantes Italianos in the state Rio Grande do Sul, Brazil. Two natural streams which received wastes from the activities of family agroindustries were monitored during nine months, as from September 2008. The water of the streams Abatedouro de Aves and Embutidos were sampled at three different sites (source, upstream, downstream of each agroindustry). Twenty-four variables integrating chemical, physical and biological water parameters in 162 samples were evaluated. Results showed that wastes from agroindustries have reduced water quality. The source of the stream Abatedouro de Aves has a significantly greater riparian vegetation and a better water quality than the source of the stream Embutidos. Downstream collection sites of the stream Abatedouro de Aves is more liable to diffused contamination. Water quality of the stream Embutidos is worse than that of the stream Abatedouro de Aves. Improvement in waste treatment is necessary and the regeneration of riparian vegetation in the two streams should be enhanced.Downloads
