Aspects of the quality of rain and urban stormwater in the Metropolitan Area of Porto Alegre, Brazil, are presented. The results obtained in the survey show a significant occurrence of chemical and acid rain in the area. The data on urban drainage quality show that, besides contamined rain, other sources of pollution such as poor garbage collection, car exhaust, crankcase leakage, and badly done street cleaning, contribute to increase the pollution of the receiving body of water, the Guaiba river.
