Brothers Jose and William Garcia lie on their bed inside their apartment in Chelsea, Massachusetts, on July 20, 2015. After their mother complained about a lead problem in a previous home they lived in, the landlord kicked them out. Soon after, Jose, left, was diagnosed with extreme levels of lead poisoning and William also showed signs of the disease. Last year, about 5,000 children in Massachusetts tested positive for elevated lead levels, according to the state Department of Public Health.
