Portuguese Abstract: Microcontaminants of emergential interest are found in the environment at low concentrations, in the range of nanograms per liter (ng / L) to micrograms per liter (μg / L). These compounds, even at small scales in the environment, are able to combat the adverse effects of man on living things. The ware with the changes of contamination are different and eliminate the volatilities of the treatment of waters and effluents are not ensure to eliminate them. Thus, the present study has the objective of monitoring the emergency events around 60% of the water supply of the Natal-RN North Zone. There were 13 organic compounds, of which 7 were classified as endocrine disrupters and five drugs were present in four sample points updated in the Extremoz-RN ETA. Of the 12 compounds investigated, 7 were detected in at least one of the collection points. The assemblies were converted into filter wash water. In crude water, Naproxen and 4-octylenol were detected at concentrations of 59.7 ng / L and 11.1 ng / L, respectively. In the treated water, Naproxen and 4-nonylphenol were detected in associations of up to 73.4 ng / L and 81.6 ng / L, respectively.
