A new state law aims to boost the number of children screened for lead poisoning. There's good reason New Hampshire is aiming for that goal.
Children aged 0-6 are the most likely to suffer permanent health and cognitive damage from lead exposure. Yet in 2013, New Hampshire tested a mere 16.5 percent of children in this age group for elevated blood lead levels. That's concerning because 62 percent of New Hampshire's houses were built before 1978 - the year the federal government cracked down on lead paint.
