Ya I was scared of Silica too. It's nasty stuff, but only airborne apparently. Any research I can find says
silica in drinking water actually has no known health effects. It's inhaling is the deadly one. (And the open pit silica was just approved haha)
In the least, drinking water is less than 5% of household water use. So even one considers silica harmful, it can easily be filtered out with RO. I don't think these conversations occurred enough.
I get the 100k people risk. It's a big swath. But given the above reality, at least let a few isolated test holes occur to prove safety risk one way or another in a contained way.
A video of the extraction technique is here. Actual real world model, not animation. It looks pretty clean honestly.
