Which of the following is NOT one of the six lead-based paint (LBP) hazards defined by the EPA?

The correct choice is that "Lead Water Contamination" is not one of the six lead-based paint (LBP) hazards defined by the EPA. The six hazards are specifically focused on surfaces and conditions directly related to lead-paint exposure.

Friction surfaces refer to areas where surfaces rub together, such as windows or doors, potentially generating lead dust from deteriorating paint. Chewable surfaces are those where children might suck or chew, like chair rails or cribs; the risk comes from the potential ingestion of lead dust or paint chips. Deteriorated paint represents paint that is peeling, chipping, or otherwise failing, posing a risk of lead exposure as it breaks down into dust or chips.

In contrast, lead water contamination pertains to lead exposure through drinking water, which is influenced by plumbing rather than paint itself, making it a different type of hazard outside the scope of lead-based paint hazards as defined by the EPA.
