Thanks for all the concern friends. The media is just super pumped to report that maybe perhaps possibly there could be something wrong with Soylent a little bit. A non-profit is press releasing up some FUD with claims that Soylent has unsafe levels of Lead and Cadmium. This story is super exciting because everyone wants a reason to hate Soylent because it is different and scary. It is super less exciting because Soylent doesn’t have unsafe levels of lead or cadmium and the lawsuit is bullshit . Soylent has completely safe levels. In fact the amount of lead you get from your tap water is probably a bigger concern than what you are getting from soylent. Let’s talk about that.
On the Soylent side: Lead in Soylent 1.5 is 9.982ug/L, less than 1/50th of the FDA requirements for infant food - Source.
For reference: “More than 40 million U.S. residents use water that can contain lead in excess of 15 µg/L - (the Federal limit)” - Source. The limits on tap water need to be much stricter than food because people drink a lot of tap water. Yet soylent is even safe by that metric. Really, if you learn anything from this it should be reading that EPA link and learning that the EPA strongly recommends that you never cook with or drink hot/warm tap water. I thought everyone knew this but apparently not. So, simple summary with caps to show relative importance:
If you didn’t see it already and don’t know why this is even being discussed, As You Sow is a new kind of legal troll  that is taking legal action against multiple food companies. Soylent is the most interesting of those companies so you really only hear about the legal action against Soylent.
As You Sow are taking advantage of the fact that California has extremely strict chemical reporting requirements as a part of proposition 65 . Ever see “WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm” ? Yep. that is proposition 65 at work. As someone with a science background I really want to rant about how bad proposition 65 is for America. I’ll spare you though. You have Google and can learn all about how misguided proposition 65 is on your own.
For some reason As You Sow thinks that Soylent hasn’t made their levels of lead public as required by prop 65. They have. I’m completely not a lawyer so it is hard for me to understand how As You Sow can make claims like this. But, wow, super smart  on their part. This is a brilliant smear campaign they are getting away with. Everyone is going to hear that Soylent is unsafe, send me links to articles about it being unsafe, and when this blows over only remember “Soylent = Bad”. No one will remember that Soylent is totally safe and well within legal limits because that news is boring.
So… I don’t know. This seems to be the way that things always happen. I guess the bright side is that it sorta tangentially gives me an excuse to talk about lead in water and remind people that there is a real danger here which is cooking with hot tap water . Thanks to those of you who shared links after reading about this everywhere on the internet. Please feel free to share any and all "don't sure hot tap water" safety links going forward here on out.
Stay tap water vigilant.

Note: I converted the units on both of these quotes so that they would be comparable. Go back to the original linked source articles if you really care to see the original units ↩
I’m bored. Are you bored? ↩
Oh. Holy shit. caps lock? This part must be important! Maybe We all should never cook with or consume tap water unless it comes out of the tap cold ↩
New to me at least, maybe this has been going on for a long time ↩
And equally shady ↩
Actually the guidelines are even stricter. You are supposed to let your tap run for 1 - 2 minutes before drinking any water out of it. Yeesh. I don’t even do that. The no hot water thing makes a lot of sense though since most lead in tap water comes from the plumbing inside homes and more lead can dissolve into hot water than cold ↩
