%X This work was developed in order to evaluate qualitatively the water from wells used by people who live in the neighborhood of Bom Jesus, in the city of Carlinda, State of Mato Grosso (MT). Two water collections were carried out in the rainfall season and two in the drought season. In each of them, twelve wells were used as samples. Questionnaires were applied for the data gathering on the care concerning wells as well as the proximity of septic tanks. The purpose of this work was to determine total coliform, Escherichia coli and mesophile bacteria, in the two rainfall seasons of the year. Results show a high level of contamination of these wells in the rainfall seasons, once the level of contamination by total coliform was of 100% in all water collections. Concerning Escherichia coli, it was observed a higher level of contamination in the rainfall period (91%) in relation to the drought period (79%), with no significant difference between the observed rainfall periods. The total counting of mesophile bacteria followed the same pattern observed for Escherichia coli, where the higher concentration was found in the rainfall period (10.430 UFC/100mL) statistically different in relation to the drought period (6.390 UFC/100mL). According to the applied questionnaires, 70% of the people use the water for human consumption, and out of these, 20% boil and/or filter the water. The wells are located at an average 8m-distance from the septic tanks. O presente trabalho foi desenvolvido visando a avaliar qualitativamente a ¨¢gua de po os r¨²sticos utilizados pelos moradores do bairro Bom Jesus, na cidade de Carlinda-MT. Realizaram-se 24 amostragens na ¨¦poca de chuvas e 24 amostragens na ¨¦poca de seca, sendo tamb¨¦m aplicados question¨¢rios para levantamento de dados sobre os cuidados que os po os recebem, bem como a proximidade de fossas s¨¦pticas. O objetivo do trabalho foi centrado na determina  o de coliformes totais, Escherichia coli e bact¨¦rias mes¨®filas, nas duas esta  es pluviom¨¦tricas do ano. Os resultados nos revelam um alto grau de contamina  o desses po os nas duas esta  es pluviom¨¦tricas, uma vez que o ¨ªndice de contamina  o por coliformes totais foi de 100% em todas as coletas. No que se refere a Escherichia coli, foi observado um maior ¨ªndice de contamina  o no per¨ªodo chuvoso (91%), em rela  o ao per¨ªodo da seca (79%), entretanto n o h¨¢ diferen a significativa entre os per¨ªodos pluviom¨¦tricos observados. A contagem total de bact¨¦rias mes¨®filas seguiu o mesmo padr o observado para Escherichia coli, do qual a maior concentra  o foi encontrada no per¨ªodo chuv
