Lead poisoning is a serious problem which can lead to adverse health problems. In children, high levels of lead can cause damage to the brain and nervous system, behavioral and learning problems, slow growth, and hearing problems. In adults, lead poisoning can cause reproductive problems, high blood pressure, digestive problems, nerve disorder, memory and concentration problems, and muscle and joint pain.

Typically, lead is found in the paint from older buildings, in the water supply, and in the environment from cars and buses.

Houses that were built before 1978 probably have paint that contains lead. Federal law requires that sellers disclose known information on lead-base paint hazards before selling a house. Sales contracts must include a federal form about lead-based paint in the building. Buyers will have up to 10 days to check for lead hazards and are likely to stipulate corrections.
