Resumo
Road runoff produced during rainfalls has significant pollutant load, which can cause important environmental impacts on waste and soil. The efficiency of a detention basin for removing heavy metals (Cr, Cu and Zn) in
road runoff was evaluated for 8 rainfalls over one year with
different intensities (between 16 mm and 103 mm) and durations (higher than 3 hours). The basin showed good performance for removing all metals for precipitation intensities between 16 mm and 103 mm and rainfall durations up
to 3 hours. The volume of the basin is suitable for retaining
all the road runoff coming from rainfalls with intensities
lower than 29.4 mm and duration longer than 6 hours. This
type of monitoring should be introduced in Environmental
Monitoring Plans of roads because it allows evaluating the
effectiveness of treatment systems and preventing the possible impacts of discharges into the environment.
