Acesso em:.https://repositorio.ufpa.br/handle/2011/10757The research was developed from September / 2015 to February / 2017 and had the objective of diagnosing and analyzing the waters of the Pericumã River in the city of Pinheiro-MA, under physico-chemical and microbiological aspects, essentially important in the characterization of water quality supply and homes. The collections were monthly at three points along the river. The analyzed parameters were: temperature, conductivity, pH, turbidity. Microbiological parameters were: total coliforms, thermotolerant bacteria and Escherichia coli. According to the results obtained it is concluded that there is a seasonal variation of the water quality of the Pericumã river in the physical-chemical parameters. Brazilian urban environments are characterized by the progressive concentration of the population, configured by a disorderly and accelerated growth that causes significant impacts on the environment, with actions that are not committed to the natural, sociocultural and urban aspects of their landscapes. Above all, due to inappropriate and improper appropriations of space for urban occupations. The landscape is subject to intense environmental fragility due to significant changes in morphogenesis, as occurs in the city of Pinheiro - MA, which represents a regional center in the center of the Maranhense Bay, where about 60% of the population lives in the urban environment of the municipality. In view of this, this research has the purpose of diagnosing the areas with socioenvironmental fragilities, of floodplain areas and urban perimeter.Acesso AbertoQualidade da águaRio Pericumã - MAOcupação urbanaMaranhão - EstadoDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::GEOCIENCIAS::GEOLOGIA::HIDROGEOLOGIARECURSOS HÍDRICOS
