Crystal Meth Lab in Slope Bstone

A few years ago, I lived in a “prime park slope” brownstone apartment–on carroll street, between 8th avenue and prospect park west. There was a neighbor in one of the ground floor apartments who I can only describe as “twitchy” and “tweaky.” He was a drawn, agitated Russian guy who always looked paranoid. It gets worse. Repeatedly, there were very, very strong chemical odors–what smelled like an industrial strength amount of nail polish remover–coming from his apartment. He actually claimed to have “spilled nail polish remover,” but the smell was on the level of industrial toxicity, and happened constantly. Finally, after unsuccessfully trying to get Greenberg, the property managers, to listen to what I was saying, I called the narcs, and then just moved out. At the time, I suspected it was probably crystal meth–but I didn’t know, as I now do, just how dangerous that was. I had no idea that it would permanently contaminate the building, etc. Now I feel like, even though it was a few years ago, that if this guy never got caught, that the entire building is probably still at risk–given that there is virtually no way that that wasn’t a meth lab. At the very least, the building should be tested. I wonder if there is any way to find out if that problem was ever addressed, or who I should contact? The property managers are clearly don’t ask don’t tell, and I already called the police back then, in the mid 2000’s. Should I post flyers in front of the building? Thoughts? I feel stupid for not having followed up on this before more thoroughly, especially given the potential damage to kids, pregnant women, and just about anybody.
