Read the EPA reports that have been posted... it contains the data from the static and roaming air quality testing. It shows that there are pm2.5 particulates around in slightly elevated amounts, but none of the chemicals from the train.

I have yet to see any hard evidence of things like chemicals from the train being detected in ground water or streams, and I have seen no evidence of anyone dying from the big, scary cloud, nor of any chemicals from the train being present in that, either.

There's a huge amount of conspiracy BS being pushed on this, so be sure to think critically about anything someone tells you about the event.

I'm still waiting to see still images that aren't 10 days old

Kinda over it, hope Bethesda is excited about doing a Fallout Ohio

Don't forget to spray your kids with DDT and buy the new lead painted asbestos walls ;) and remember we're here for your own safety (PS: regulations are bad)

The chemical from the train got burned which turned it into a different chemical. Are they only testing for purely what was in the train or the byproducts of the chemical being burned?

Both. The combustion products of any of the chemicals listed as being on the train so far are CO, CO2, HCl, and trace phosgene. Only VCM has the last two. The HCl is the biggest risk because it's the largest product by volume and because when inhaled it forms hydrochloric acid with water in the lungs. Fortunately it will combine with water in the atmosphere if it finds that first.
