Chemistry of Flint Water Crisis

Thanks for the share--great read! It takes me back to my water sampling days. It also makes me glad to be on a well (although problems can certainly occur there too).

It's amazing just how badly water wants to have things dissolved in it. I was talking with the one who serviced the RO system at work and he was always surprised by how many people drink distilled water for touted health benefits. Distilled water (free from dissolved metals and minerals) is very "hungry" for any metals and minerals it can dissolve--it strips out crucial minerals and trace metals in the body when consumed.

It sure has taken us quite a while to learn about the interactions between liquids and metals. I like the story about the toxic tomatoes. There was a time when tomatoes were thought to be toxic because those who ate them were getting ill. It turns out that it was a result of the lead that leached from the pewter dishes due to the acidity of the tomatoes.

Water chemistry sure is a complex science. It's fascinating what steps are taken with treatment of both drinking water a waste water.

 

Do not trust your government when they say the brown water is safe to drink. Make them drink it.

My brother was down here for a conference a couple of weeks ago, and they were talking about water treatment, and of course the gross incompetence here, not only in creating the problem, but telling people it was safe.

 

Accessible, accurate science. Always worth a like. A rather small proportion of journals actually put effort into this aspect of science communication.

Aviation fuelers (drive the trucks) are exposed to 100LL on a daily basis. LL stands for low lead (as you'd guess) but it really is quite high. I think it would be interesting to study their 'chemistry'. Offer free haircuts and sweep up the trimmings.
