Evaluation of the drinking water quality surveillance system in the metropolitan region of Rio de Janeiro

The present work evaluated the surveillance of the drinking water quality information system database and correlated the findings of the microbiological analysis with the distribution of intestinal protozoa from the metropolitan region of Rio de Janeiro. From the database, we obtained 1,654 georefer...
