While we sit and sympathize with the residents of Lexington Manor, who have seen their neighborhood turned into an EPA Superfund site due to lead and arsenic contamination from a former firing range, we may be unwittingly creating the same mess in our own backyards.
Last week, in a fit of landscape envy, I decided something needed to be done to get my lawn to look as deep green as those of my neighbors. People in the know suggested an iron supplement would do the trick, so I went to my local garden center and bought a product called Ironite. According to the label it is a natural source of iron, zinc, calcium and other micronutrients. Perfect. Too bad the label didn’t list everything that was inside the bag.
A Google search on the product turned up reports that Ironite is also a natural source of arsenic, lead, cadmium and a host of other hazardous heavy metals. And not just trace amounts. Minnesota Department of Agriculture tests showed arsenic levels of 3,000 to 6,000 parts per million, or about 1,000 times higher than those found in other lawn care products. Lead levels were about 3,400 parts per million. Now I am no scientist, but by my rough calculations I figure that my four bags of Ironite contain about a half pound of arsenic and almost as much lead. So how did all this stuff get in there?
It turns out that the ‘natural’ source for Ironite is derived from the tailings of a former silver mine in Arizona. Under any other circumstance the source for Ironite would be considered a hazardous waste, but a loophole in the federal law not only exempts mining wastes, but makes it difficult for states to regulate the sale of products made from them. Ironically, it is recommended that any unused Ironite should be handled as a hazardous waste when disposing.
To be fair, the manufacturer of the product claims that the hazardous components in Ironite are trapped in minerals that make them safe for general lawn care. So safe in fact, that their web site compares the product label to one on a box of breakfast cereal. I am not sure which breakfast cereal that could be, but in my mind I have a picture of the Incredible Hulk downing a nice bowl of heavy metals.
Perhaps the product is safe, but it seems disingenuous to claim it is natural and compare it to cereal. At the very least, the label should carry a complete list of the compounds found in the product. That way the consumer could make an educated decision whether or not to use it. But that may be exactly what the manufacturer fears most.
What really scares me, though, is that despite what I have learned about Ironite, I still tried to rationalize using it on my lawn because of my deep-seated desire for green grass. If I am willing to rationalize away the risks in pursuit of green grass, is it that far-fetched to imagine the manufacturer rationalizing away the risks in pursuit of another type of green.
