Résumé partiel
With an estimated population of 3.5 million inhabitants, the state of Rio Grande do Norte (RN) has a large part of its territory inserted in the Brazilian semiarid region, which, due to its natural characteristics, faces difficulties resulting from water scarcity, which is burdened when the quality of available water is degraded as a result of the natural geological characteristics and human activities developed in the region. In this perspective, the general objective of this research is to investigate the water quality of state reservoirs and their relevance as a risk factor to the health of the population. The scientific activity covered was planned in three parts. Chapter 1 deals with the characterization of the water quality of a representative reservoir in terms of its relevance to regional supply. For this, the selected study area was the municipality of Caicó, inserted in the Piranhas-Açu Hydrographic Basin domain. The research was carried out through water quality analysis represented by the Trophic State Index and qualitative quantitative occurrence of cyanobacteria. The database used was obtained from the Água Azul Program. The results achieved were support for the definition of the potential health impacts linked to eutrophication in the period from 2008 to 2016. In chapter 2, considering the contribution to the knowledge of the perception of environmental quality from the perspective of society inserted in the area of interest, a study of environmental perception was carried out through the application of interviews to residents of different neighborhoods in the city of Caicó, contemplating information referring to sociodemographic characteristics such as : infrastructural and economic aspects of family nuclei, information on social, cultural and sanitary characteristics , in addition to environmental aspects and their relationship with them. The results obtained provided relevant information related to the environmental problems experienced by the population, providing a subsidy to promote the improvement of the quality of the environment in which the population is inserted.
