"Oakland Unified School District began this school year with some unsettling news: the drinking water in the district’s schools had tested positive for dangerously high levels of lead.

The district had found high levels of lead in the water during tests conducted over spring and summer, but it didn’t share those results with parents and staff until this August.

Lead testing hasn’t been required in California schools for the last five years. That means Oakland Unified is unusual among California school districts in that it knows that there’s a lead problem at all."

Thank you! And corrected.

You're very right about prions. But there's more passing through reverse osmosis membranes than meets the eye.

Size cut-off is not the sole trans-membrane transport process. The material of some membranes allow the diffusion of some molecules - roughly, hydrophobic membrane materials allow diffusion of hydrophobic molecules.. its more specific than this, though.

There are targeted studies to assess the removal of micropullutants that show that some micropollutants can pass membranes even though their size is bigger than what would reasonably be expected to be retained.

I don't know anybody studying this with broad spectrum techniques that uncover unknown-unknowns.

I agree, the key is disclosure and transparency. Mandatory, if necessary.

IR's México, warm and dry, it is a pretty safe bet that they'll have evaporative cooling.

The alternative, without evaporative cooling, implies the release of pretty warm water. Which, if you go see has some damnning environmental impacts and can even be the limiting factor in say nuclear plants sizing.

Moreover, you talk as if the withrawal of information by these datacenter companies should be used as justification for "we don't have the whole information why are you assuming the worst". Thats a very flawed logic on itself but ..well, look into some environmental history books and tell me what you see when companies use that argument as justification not to look closer.

I'm conflicted about this upvote.

Laundry softner?! Don't use that, with the help of having soft water.

Yes, I thought that too. Been avoiding running plastic stuff in my dishwasher for 5 years ...and always using these packs.. Colour me 'not cynical enough'.

Microplastics pilling on.

10w is impressively low. And totally justifies the convenience in a lot of cases.

Thanks for the info.

10watts on stand-by? That's impressive. I didn't find that info on the website. Can you point me to where that is? plz
