The General Assembly finds that: lead paint is present in a large percentage of residential properties in the State, particularly residential rental properties constructed before 1950; lead paint on the friction surfaces of windows is a leading cause of lead poisoning; lead poisoning harms the health and well-being of children and pregnant women and causes substantial long-term public costs for medical expenses and additional education; and reduction or elimination of lead in the environment will reduce: the risk of lead poisoning of children and pregnant women; the incidence of learning disabilities and behavioral problems in children who live in older housing; and the cost of publicly financed medical care.
