Introduction: Sanitary restrictions in Brazilian rural settlements can affect water quality and imply adverse effects on human health. Objective: To evaluate the quality of water consumed in a settlement located in Ribeirão Preto (SP). Methods: The rural settlement studied has 6 artesian wells for public supply; however, the water does not undergo any treatment process. A total of 234 water samples were collected from 77 households, distributed in 7 clusters in the settlement. The samples were evaluated for microbiological (total and fecal coliforms and parasites) and physical-chemical (pH, turbidity, and metal concentration) quality. The results were compared with the potability standards of Ordinance #888/21 of the Brazilian Ministry of Health. Results: An increase of total coliforms was detected that in 59.7% of the samples, 13% for fecal coliforms and 20.8% helminth larvae. The physical-chemical analyses showed that in 28% of the residences the pH was below the recommended value. The concentration of metals was in accordance with Brazilian recommendations, with the exception of lead in two households. Conclusion: Access to drinking water is a fundamental right according to the United Nations Organization (UNO); however, the study confirms that the absence of satisfactory water supply systems impairs the quality of water consumed in the settlement and represents a risk to the health of the community.
