Análise físico-química e microbiológica de água da Lagoa do Portinho, localizada no Município de Parnaíba - PI

Abstract

The State of Piauí presents several water resources, where the lagoons are evidenced, among them the Portinho Lagoon, located in the municipality of Parnaíba-PI. The lagoon Portinho years ago presented great socioeconomic value for the inhabitants of the region, since it was used mainly for fishing, bathing and recreation by local residents and tourists. Unfortunately the volume of the water body of the lagoon was diminished by the scarce period of drought and silting of dunes in this region. The study of physicochemical and microbiological parameters of water is one of the main instruments for a previous analysis in the elaboration of policies of planning and management of water resources. Therefore, the samples of the water samples were taken in the dry and rainy period of the region. In the microbiological analyzes the presence of total and fecal coliforms was verified, and in the physicochemicals a low oxygen content dissolved in the water, confirming a parameter of pollution. The Portinho Lagoon is one of the tourist heritages of the city of Parnaíba, therefore it needs social sensitization for its conservation and preservation.
