One of the best BMPs that a facility can employ is site sweeping and trash/debris pickup. We harp on this a lot because source control and good housekeeping can make a big impact on your stormwater sampling results. At least 75% of the ERA Level 1 evaluations we do result in a recommendation for increased site sweeping. Especially for Total Suspended Solids (TSS) issues and particulate metal exceedances (e.g. zinc and copper) in industrial stormwater, good housekeeping via site sweeping works extremely well. There are a few options to do site sweeping:
- Manual sweeping with a push broom and dust pan.
- Use a shop vac or drum vac plus broom.
- Buy, lease, or hire a street sweeper (regenerative air to vacuum only to floor scrubber).
