Water quality in streams is determined by several factors, including geology, topography, climate, and anthropogenic changes. This study aimed to assess the effects of watershed physical, morphology, and precipitation seasonality on the water quality of two streams that supply drinking water to rural settlements and urban areas in the Cerrado-Amazonia transition region. We monitored 16 physico-chemical attributes of water at six different sample locations over three years (2013–2016). Our results indicate that eight of these physico-chemical attributes did not meet the standards for safe drinking water established by Brazilian legislation. Precipitation seasonality, degradation of riparian zones, stream length, and watershed slope were the most important predictors of impaired water quality. Our results highlight the importance of restoring and conserving riparian forests in order to maintain drinking water quality.

Cenários espaçotemporais para o desmatamento na Amazônia Legal brasileira
Pesquisadores do IPAM (Instituto de Pesquisa Ambiental da Amazônia) criaram, em parceria com o Banco Mundial, uma plataforma onde é possível prever o risco de desmatamento e estimar as áreas futuramente desmatadas nos estados da Amazônia Legal. A pesquisa pretende...
