Abstract

O presente trabalho foi realizado no estado de Rio Grande do Sul e teve por objetivo avaliar a qualidade das águas dos principais afluentes da Lagoa Mirim entre os anos de 1996 e 1998, utilizando-se o Índice de Qualidade de Água de Bascarán (IQAb). Como resultados finais, verificou-se que a qualidade hídrica dos afluentes da Lagoa Mirim avaliados foi, no geral, aceitável, tendo como poluente mais impactante em relação à qualidade das águas o fósforo. Além disso, o índice refletiu a realidade ambiental verificada na região, onde é realizada a agricultura intensiva e o lançamento de grande parte dos efluentes domésticos e industriais sem prévio tratamento nos mananciais.
