Did you know that children in Cuyahoga County are impacted by lead at a rate doubling the national average? Lead can be found in dust, soil, water pipes, some household products, and especially in paint used in homes built before 1978. Children under six years old are the most vulnerable to lead poisoning, which can lead to damage to the brain and nervous system, resulting in learning and behavior problems, hearing and speech problems, and delayed growth and development.
