What the actual fuck? Was this written by the meat production/processing industry which is the actual cause of all those nitrates‽
There's no fucking way that a handful of Amazon data centers are using up enough water to increase nitrate concentrations. They're waaaaaaaay too small for that.
Think about it: If you evaporate that much water full of nitrates on copper/aluminum heat sinks what do you get? A thick ass film that ruins their effectiveness. Calcium/scale is much worse so what do data centers do? They preprocess and filter the water.
When you filter nitrates out of the water you end up with slime. What do you do with that slime? You throw it away. As in, in the trash. You don't flush it down the drain! That's a one-way ticket to clogged drains!
Some data centers can use a lot of water but not enough that it can make a dent in nitrate concentrations in a region that has been polluted by the meat processing industry for decades.
Amazon is a villain, yes! But they're not the correct villain for this issue.
