Removing lead from homes, schools, and daycare centers could be a ‘gigantic leap forward’ for public health. (via grist)
While the United States banned lead paint nearly half a century ago, the rules didn’t require removing the toxic substance from existing buildings. An estimatedbuilt before the 1978 ban still have lead paint, and nearly 4 million of those homes are occupied by families with children younger than 6. The EPA’s new rule would virtually prohibit lead dust, reducing exposure for between 250,000 and 500,000 children under the age of 6.
Any sign of lead in a home or childcare center would classify it as a lead hazard. That would in turn—say, to the families of kids attending the daycare or to prospective home buyers—and potentially require that the lead source be removed. The only exception is for contamination that existing cleanup methods can’t get rid of.
The plan was decades in the making. In 1992, after scientists found lead exposure was widespread among children, Congress passed a law requiring the EPA to establish the first hazard standard for lead in dust. But the agency was slow to create the standard, waiting until 2001 to do so, and it failed to tighten the rules when scientific evidence showed that lead was a health hazard even at the smallest levels of exposure..
unearthed a hidden source of lead contamination in the environment: a countrywide network of lead-coated cables laid by telecom giants such as AT&T and Verizon that have gone unnoticed by regulators. It’s another sign that removing lead, with its once-ubiquitous use in the country’s construction, remains a daunting task.
