Abstract
This study aimed to analyze the bacteriological quality of the Salgadinho river water in Juazeiro do Norte, Ceará, by researching total and thermotolerant coliforms. The collections were made where it is evident the dumping of domestic and industrial waste, from August to September 2016 with ten days apart. The analysis procedure was performed in triplicate using the quantitative or most probable number (MPN) multiple tube method. 100% positivity for total and thermotolerant coliforms was confirmed in all analyzed samples, with high proportions recorded (≥ 1600 MPN/mL). This indicates that these waters are unsuitable for bathing and consumption, representing possible transmitters of waterborne diseases. Thus, a regular assessment of river water is essential, as well as seeking to raise public awareness and local residents about the preservation and importance of the river for the Cariri Region.
