According to EPA recommendations, how should a carpeted area of 50 square feet contaminated with clean water be treated?

1. Washed with soap and water

2. Wet vacuumed, HEPA vacuumed, or discarded in well-sealed plastic bags

3. Left to dry naturally

4. Covered with plastic until dry

The correct answer is: Wet vacuumed, HEPA vacuumed, or discarded in well-sealed plastic bags

When dealing with a carpeted area of 50 square feet that has been contaminated with clean water, the recommended action is to use methods such as wet vacuuming, HEPA vacuuming, or discarding the contaminated material in well-sealed plastic bags. This approach is appropriate because it directly targets the removal of moisture from the carpet, which is crucial to prevent mold growth and ensure proper sanitation. Wet vacuuming is an effective means of extracting excess water from the carpet fibers, while HEPA vacuuming can help eliminate any particulate contaminants that may have collected in the carpet during exposure. If the contamination is extensive or the carpet cannot be properly cleaned, disposal in sealed plastic bags prevents any potential spread of contaminants to other areas, addressing both remediation and safety concerns. Natural drying alone does not remove the moisture from within the carpet's fibers, thus increasing the risk of mold development. Covering with plastic would trap moisture under the surface, further promoting a conducive environment for mold growth. Hence, the combined measures of properly vacuuming and sealing the material ensure a more effective and comprehensive treatment of the affected area.
