With the exception of being stuck in holiday chitchat with a local Land Use chair on new and exciting zoning proposals, few things can make an unwitting conversant's eyes glaze over quicker than a holiday conversation (or, frankly, any conversation) with an enviro in command of "all the numbers."
With that in mind, we'll do our best to keep it as simple and as accurate as possible. If you have facts, figures or any other mitigating formulas to offer, by all means, please use the comments section to offer correction. We're all ears.
Here's what we have:
Hex 6 in dirt carries a different cancer risk than Hex 6 in water.For the New Jersey Environmental Protection Agency, the "dirt multiple" for health risk is 20 ppm (parts per million)...
According to NJEPA...
"...for every 20 ppm [in soil] there are two (2) additional cancers per 100,000 exposed over a lifetime."
In December 2009, the industrial use Headworks area reportedly tested Hexavalent Chromium 6 soil levels at 530 ppm.
530 ppm divided by 20 ppm = 26.5
26.5 x 2 cancers = 53 additional cancers per 100,000 humans exposed daily over a lifetime (70 years).
Good thing nobody got exposed to this high a risk.
Except, possibly, the horses and the people on the horses and the bike riders riding bikes next door.
And the hardhats without breathing masks running the heavy machinery to move Headworks soil around.
That's probably it.
Unless, of course, big dry winds kicked up and a lot of dust went flying from the site.
That wouldn't be good.
