Most sites I can walk and size up without much trouble now. But then there's an old contaminated one, chemicals soaked into the ground for decades, plumes moving underground where I can't see, and I'm stumped. I don't trust my own read, and the stakes are too high to guess.
More people experience this than they realize.
You can assess most sites, but the complex contaminated ones still stump you.
If this sounds familiar, the Library can help you find the bigger picture.
