ABSTRACT
The objective of this study was to assess the quality of rainwater in the city of Itajubá, MG. Therefore, samples were collected in order to analyze rainwater quality after the water had drained through three materials: asbestos, zinc and ceramic. Direct sampling was also performed in order to compare results and to verify changes in rainwater quality. It was observed that the quality of rainwater varies with the material through which it flows, changing parameters such as pH, hardness, alkalinity, turbidity and coliform concentration. Therefore, the surface material in rainwater collection systems can modify water quality and thus affect the final suitable uses of this water. Although the meteoric waters of Itajubá had a low degree of contamination, it was concluded that the treatment of these waters must include the removal of solids, pH adjustment and disinfection, which will render them an advantageous, sustainable and affordable alternative for use in times of shortage water.
