When Did Lead Become Dangerous? How Our Understanding of Risks Changed Over Time

Rural Missouri Town Reflects on Lead’s Impact 40 Years Later

Forest City is a very small town of about 250 people, nestled in very small, very rural Holt County in Northwest Missouri. The whole county has about 4500 residents. Mayor Greg Book was born and raised in Forest City, and he refers to his home as “a Mayberry type of town.” The town is quiet and charming, but there isn’t much to it. There is a diner, open until 2:00 p.m., a historic city hall, open until 2:30, and a Drug Store Museum, open for four hours every Sunday. It only takes a minute to drive through this little Missouri town, but four miles up the road in Canon Hollow, down a winding, two-lane county road, sits Exide Technologies, a lead battery recycling plant that has been operating since 1975. Holt County has no other connection to the lead industry. It’s not in any of Missouri’s lead belts, and agriculture is the major way of life, not mining. According to the Bureau of Labor Statistics, Holt County has around 1300 employed people, and Exide employs about a hundred of them.

Educating a County on Lead Risks

Penny Crump sits at her desk, and opens up a lavender-colored binder she calls her “lead binder.” As the lead coordinator for Jefferson County’s Health Department, she’s in charge of keeping track of the children in the county who have elevated lead levels. Each case is in that lavender binder. “This is the list of my kids. So this is basically the one I just got that was high. The date we opened her case. When is she next due?” she said. Crump makes phone calls to parents, guardians and doctors to make sure they’re following up on the child’s lead testing. In some areas of Jefferson County, all children under the age of 6 are required to be tested for lead exposure because of former and current lead mining and smelting operations.Everywhere else in the county, parents fill out a survey first to determine risk of exposure. Depending on the answers, kids get their blood levels tested. If a kid tests high, it’s Crumps job to make sure parents understand what steps they need to take at

Lead-Based Batteries, Long a Standard, Face New Economic Threat

While you’re reading this, Winston Kliethermes is probably thinking about batteries. He owns B & W Battery & Auto Repair in Jefferson City, and he says he’s been working with car batteries since 1974. There are a lot more kinds of car batteries around now, but almost all of them have one element in common: lead. Lead-based batteries have long been the standard for transportation like cars or boats, and companies across the globe also use lead-based batteries to power their servers in case of emergency. It’s a well proven system. “Batteries in general have stayed the same for 50 years,” Kliethermes said, “At least as far as the way they look and what they do.” Propelled by the growing number of cars in places like China and the increasing need for online data centers, the lead battery industry is flourishing. Analytics firm Grand View Research valued the market for lead-based batteries in 2015 at almost 47 billion dollars, and they’re forecasting a growth of nearly 4 percent a

Legacy of Lead: The Right Place to Teach Mining

Today, Missouri is home to three major lead districts and the state has accounted for more than 90 percent of the nation’s lead production over the last century. But actually getting that lead out of the ground requires a lot of scientific knowledge and the hard work of underground laborers. Missouri University of Science and Technology in Rolla plays an important role in the history of lead mining in Missouri. “The university is really, really good,” Professor Paul Worsey said, “It’s got a good reputation, for practical engineers.” Worsey has been teaching mining and explosives engineering at Missouri S&T for 35 years. He says a big strength of the program is the experimental mine about five minutes away from the Rolla campus. “One of the great things about this mine is that students get to do things,” Worsey said, “They get grubby, they get dirty, they have realistic conditions, and when they leave here, they know what it is all about.” The land for the mine was first purchased

When Did Lead Become Dangerous? How Our Understanding of Risks Changed Over Time

Bill Haggard is the mayor of Herculaneum, Missouri, a town of 4,000 about a 30 minute drive south of St. Louis. He’s also the fire chief, president of the historical society and a retired teacher, among other distinctions, although he identifies first as a “lifelong resident.” For more than a century this town was built up around the lead smelter that sat along the Mississippi River. Today, though, most of the houses remaining in the hollowed out center of town are marked in spray paint with a bright orange ‘X.’ “If they have an ‘X’ on them they’re coming down,” Haggard says while driving by houses slated for demolition.
