Correlação entre qualidade da água e variabilidade da precipitação no sul do Estado do Amapá

Abstract

The objective of this investigation was to quantify the variability of physico-chemical and microbiological water quality parameters under the influence of monthly rainfall in the Lower Jari River, Amapa State. This stretch of the river basin is considered to be at high risk of periodic flooding. The methodology consisted of monthly sampling of surface water from November 2009 to November 2010 at four sampling sites located on a 36 km stretch in front of Laranjal do Jari City, Amapa. In total, sixteen parameters of water quality were analyzed in each sample. We compared the results with the quality standards of CONAMA Resolution
