In the heat of a Democratic presidential debate on March 6, former Secretary of State Hillary Clinton made a rather ambitious pledge to remove lead "from everywhere." Just a few weeks later, Clinton outlined a more detailed plan that falls far short of total elimination. However, the new plan has a much better chance of achieving what should be the ultimate goal: protecting people from the toxic effects of lead exposure.
"I want us to have an absolute commitment to getting rid of lead wherever it is, because it's not only in water systems. It's also in soil, and it's in lead paint that is found mostly in older homes," Clinton said.
"We will commit to a priority to change the water systems, and we will commit within five years to remove lead from everywhere."
That's partly because, before the health hazards of lead were scientifically catalogued, the so-called "father of all metals" was commonly used in household plumbing and water systems all across the country, such as the one in Flint, Michigan.
Additionally, despite a growing body of evidence indicating serious health impacts, lead was also the common denominator in many ubiquitous products including ammunition, ceramics, batteries, cosmetics, house paint and gasoline throughout most of the 20th century.
That's all on top of lead contamination from industrial sources, including lead smelters, mining and refining operations
Leaded gasoline was a particularly invasive product, as it resulted in both soil and air-related exposure. Federal officials pushed for a limit on lead in gasoline beginning early in the 20th century, but industry lobbyists prevailed until the U.S. Environmental Protection Agency was created in 1971 and finally gained enough support to begin taking action in 1975.
In other words, lead is everywhere.
The basic premise is that a good proportion of lead exposure today comes as the result of materials used in buildings built before 1979, meaning that the property owner is responsible for addressing the problem. Soil contamination on private property is another major issue. Toys, employment and hobbies can also be portals for lead exposure.
Therefore, EPA's guidelines focus on enabling individuals to asses their risk level and take steps to avoid exposure. That includes guidance on finding qualified contractors to do any lead-related work on the property.
The new Clinton lead-hazard plan is not quite as ambitious as the original iteration, but it goes far beyond this basic guidance.
Kevin Drum of Mother Jones covered the new plan, described by Clinton within a broader eight-point speech on environmental justice at the National Action Network Convention in New York City on April 13.
As Drum reports, the new plan sets a five-year timeline for eliminating lead as a "major public health threat." Note that the plan no longer calls for the simplistic but unattainable goal of eliminating lead outright:
Drum wrote: "For every dollar invested in preventing childhood exposure to lead, between $17 and $200 is saved in reduced educational, health, and criminal justice expenses and improved health and economic outcomes — but the few federal programs that exist are inadequate to address the scope of the problem and have seen significant budget cuts and volatility in recent years."
"... writing a national plan to eliminate the risk of lead exposure from paint, pipes, and soil within five years; align state, local and philanthropic resources with federal initiatives; implement best prevention practices based on current science; and leverage new financial resources such as lead safe tax credits."
However, it's a good start for a realistic, long-term approach that gets solid results.
In addition, it puts the force of presidential leadership to work on nudging private industry in the direction of a broader goal to find non-toxic substitutes for lead in art supplies, medical equipment and other common products.
