Abstract

A study was conducted to evaluate the biotic index BMWP applicability in order to measure water pollution and, to display the physical environment protocol on the right zone of urban fluvial stream Aguas Blancas in Acapulco, Gro., a week after the dry season; three collection points were established. Taxonomic determination groups went to Family, recording 8 orders for this zone of the basin. Diptera (Chironomidae) was the most abundant. The BMWP was 67, which indicate regular water quality with eutrophication signs, which is interpreted as moderate contamination ecosystem. The built index for the physical medium was 1.4, is interpreted as stream with deteriorating conditions
