Objective was to evaluate the raw and treated water quality in Water Treatment Plant (WTP) of the Laranjal do Jari County, Amapá State, Northern Brazil. Water samples were collected at two sampling sites. PT 01 in Parshall flume, used to determine the flow near the WTP which were collected four samples, three for pH, turbidity and apparent color, and for analysis of Total Coliform and Escherichia coli. PT 02, located at the output of treated water reservoir, we analyzed the same variables of the PT 01 and aluminum. The samples sent for microbiological analysis and aluminum were collected with sterile glass recipient and the other with polyethylene bottles, packed in polystyrene foam container with ice and sent to the laboratory. Even with compromised structural conditions, the values for the variables turbidity and apparent color, total coliforms, E. coli, free residual chlorine and aluminum were in accordance with standards established by the Ministry of Health no 2914/11, noting as well that only the pH of the treated water was at odds with that ordinance.
