Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

Which of the following is a safe drinking option in areas with lead contamination?

1. Tap water

2. Bottled water

3. Filtered water from pitchers

4. Rainwater

The correct answer is: Bottled water

Bottled water is considered a safe drinking option in areas with lead contamination because it is typically sourced from a regulated supply and undergoes filtration and purification processes to remove contaminants, including lead. These stringent standards help ensure that bottled water meets safety regulations established by health authorities, making it a reliable choice when there is a concern about lead exposure from other water sources. While filtered water from pitchers can also be a safe alternative, the effectiveness of these filters in removing lead can vary based on the specific filter technology used. Not all pitcher filters are certified for lead removal, so relying solely on them can pose a risk if the filter is inadequate. Tap water, though convenient, is more likely to contain lead in areas where plumbing infrastructure is old or deteriorating, as lead can leach from pipes and fittings. Rainwater can also pose risks since it may pick up pollutants during its collection and lacks the treatment regular drinking water undergoes. Therefore, bottled water remains a safer, assured option in these contexts.
