RESUMOAs doenças de veiculação hídrica são responsáveis por milhões de mortes todos os anos no mundo. Tais doenças estão relacionadas à falta de saneamento básico e água de qualidade para consumo humano. Em Cuiabá, MT, o bairro Pedra 90 apresenta problemas relacionados à falta de água em condições adequadas de quantidade e qualidade, o que levou a população a construir poços rasos em suas residências para garantir um abastecimento alternativo. Este trabalho avaliou a qualidade das águas de dezessete desses poços e identificou que os mesmos apresentam contaminação por Escherichia coli e bactérias heterotróficas, provavelmente por estarem próximos às fossas rudimentares que são comuns na região. O consumo dessas águas representa risco à saúde da população. PALAVRAS-CHAVE: WATER QUALITY OF SHALLOW WELLS IN AREA WITH LACK SANITATION IN CUIABÁ, MT: MICROBIOLOGICAL AND PHYSICAL-CHEMICAL EVALUATION AND HEALTHY RISKS FACTORS ABSTRACTWaterborne illnesses are responsible for millions of deaths every year in the world. These illnesses are related to lack sanitation and unsafe water for human consumption. In Cuiabá, MT, the Pedra 90 Neighborhood has problems related to quality and quantity of water which led people to build shallow wells in their residences to ensure an alternative supply. This study evaluated the water quality of seventeen of these wells and found that they are contaminated by Escherichia coli and heterotrofic bacteria. The proximity of the wells to rudimentary tanks, that are common in the region, can explain this microbiological contamination. The consumption of this unsafe water can be harmful to population health.
