Objective: to identify the relation between mortality rate by specific cause and atrazine concentration in drinkable water, pointing the crops that use this pesticide in the state of Rio Grande do Sul (RS). Method: ecological study. Were selected 19 RS cities that had atrazine concentration in the drinkable water in the period of 2016 and 2017 and in this way it was performed a search of the crops related to atrazine use. The data search occurred through the following databases: DATASUS, SISAGUA, SIGA and FEE. Spearman bivariate correlations were performed to evaluate the relation between mortality rate and water concentration of atrazine. Results: The search shows three cities with atrazine contamination in the drinkable water which have values equal or higher than the allowed at Brazil (≥ 2 µg/L). The mortality rate of the genitourinary system was positively related (r=0,419; p=0,047) to the atrazine levels in the drinkable water. About the crops, corn was the prevailing. Conclusion: deaths related to the genitourinary system are possibly related to the excess of atrazine in the drinkable water from agriculture use.
