Abstract— The low quality of water associated with the lack of basic sanitation, are some of the main factors that imply the transmission of diseases to the population. Objective: To assess social and individual vulnerabilities for infection by waterborne diseases in floodplain communities in the municipality of Santarém- Pará. Method: This is an epidemiological, cross-sectional, descriptive, analytical study with a quantitative approach, carried out through statistical surveys, transcribed for the SPSS program by performing the X 2 test ( Chi-square ). Result: All data obtained showed significant p. Conclusion: Socioeconomic factors influence directly or indirectly on the human being's life condition, reflecting on the health and disease process, on the living conditions of riverside communities in the Amazon region. Keywords— Social vulnerability, Water, Water treatment. I. INTRODUCTION According to the World Health Organization, 85% of the population is affected by pathologies acquired from the ingestion of water or food contaminated with their respective pathogens. Thus, the low quality of water associated with the lack of basic sanitation, aggravated by the insecurity of the water coming from the population's supply system, the precarious conditions of hygiene, the very environment and provision of water and floods, are some of the main factors that imply the transmission of diseases to the population 1,2 . The fact that water is distributed irregularly in different regions of Brazil makes it necessary to know how it is arranged, and the environmental conditions in which it is inserted, since these factors can directly influence its quality, making it susceptible to possible contamination 3 . In rural areas and in floodplain communities, the risks of outbreak episodes are higher because of the possibility of contamination of water collections with pits and pasture areas occupied by animals 4 .
