I’d say herbicides are the main culprit when it comes to water pollution since they get used way too aggressively in places they probably shouldn't be. That said, I don't think the US has much of a problem there yet; compared to other countries, it's practically negligible. Industry isn't even at a level where they're using the really nasty stuff, like mercury, which is the worst offender in gold refining. Fortunately, that process was phased out ages ago and nobody touches it anymore. Honestly, I don't think water filtration makes a massive difference for your health or blood pressure—it's really just down to personal preference. I know people who swear by having a specialized filter just so their water stays at room temperature 🙂 which is pretty ridiculous; they probably only bought it because they saw someone else with one. My other issue is with blood pressure monitors. I have both a classic manual one and a digital Omron that's ISO certified, which is rare. If you have even a slight arrhythmia, don't bother with the digital one; it won't give you anything close to an accurate reading. For someone with normal health, my experience shows a discrepancy of about +/- 15 mmHg compared to the manual one, which I figure is within the margin of error.
