Arsenic is old news. It’s been poisoning wells since ancient Rome. But now you have the power of molecular rejection. You get the last laugh.
So go ahead, buy a reverse osmosis system. Watch it hiss and gurgle. Brag to your friends about your “semi-permeable membrane.” They’ll think you’re a wizard.
Your faucet is now a tiny, furious scientist. It crushes arsenic molecules with sheer pressure. And you? You just saved your own bacon. Cheers to that.
