QUALITY OF WATER RESOURCES IN THE CATALÃO LAKE FLOATING COMMUNITY, IRANDUBA-AM

Abstract

In the Amazon region there is the greatest surface water availability in Brazil, however, part of the population does not have access to potable water for domestic supply, which requires a certain quality standards. In this context, the Catalan Lake Floating Community is home to 86 families, where the use of this natural resource may possibly to lead a contamination by biological agents that promote the proliferation of water diseases. The goal of this survey was to evaluate the water quality in the Catalan Lake, where the Catalan community is located through the water quality variables, fecal coliforms, temperature, hydrogen ionic potential (HP), electric conductivity (EC), transparency, dissolved oxygen (DO) and turbidity to check if these are in accordance with uses made by the population and current legislation. The methodology consisted in verifying the uses of water by the residents through interviews. The field work was carried out to collect water samples in loco during the flood period and when it rains a lot. Therefore, according to the results obtained through the variables analyzed, the water of the lake is not suitable for some uses carried out by the community, according to Brazilian law.
