| Summary: | 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 runoffwas evaluated for 8 rainfalls over one year with
different intensities (between 16mmand 103 mm) and durations
(higher than 3 hours). The basin showed good performance
for removing all metals for precipitation intensities
between 16mmand 103mmand 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 29.4mmand 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. |
