Which method is described as effective for lead dust clean-up according to the EPA?

Wet mopping is recognized by the EPA as an effective method for lead dust clean-up. This technique helps to minimize the disturbance of lead dust particles, which can become airborne if not properly managed. By using a damp mop, contaminants can be captured effectively without the risk of them resettling or becoming airborne, thus significantly reducing the potential for lead exposure.

In contrast, methods like dry sweeping or using a standard broom can inadvertently kick up dust, allowing lead particles to disperse into the air. Vacuuming with a standard vacuum may not capture the fine lead dust effectively, unless the vacuum is specifically designed with HEPA filters that can trap such small particles.
