See, I looked this up for my project. They say arsenic gets in from rocks underground, and tube wells pull it up with the water. Ten micrograms per litre is the safe limit, but honestly, those numbers feel far away. For me, clean water means our hand pump that didn't go rusty last year, not a lab test. My worry is my sewing machine rusting in the monsoon, not invisible things in water.
