Even regular tap water in many US cities is contaminated with PFAS and other pollutants.
When water does reach a house, only about 5-20% is used for cooking or drinking - the rest for watering plants, showers, toilet flushing, washing.
Is it better to just outfit each home with an under-sink reverse osmosis machine and pipe in raw reservoir water?
- autoexec 4y agoDoes anyone have a map of US cities without safe drinking water? I can't keep track at this point. Why isn't the EPA on this? They should have a dashboard or something by now.

- kurupt213 4y agounder sink would be too inconvenient and all the RO membrane cartridges, or millipore filter cartridges are contaminated with PFAS, anyhow. it's literally everywhere. We have to run ours for 30 minutes before taking the ultra-pure water at the lab to drop the levels down to 'baseline'. Otherwise, the built up levels blow out the instruments.
- tophi 4y ago30 minutes for every new filter? Or every time?
- kurupt213 4y agoEvery time. They concentrate the pfas in the water, which bleeds through the cartridge as it sits there between uses, meaning all the diffusion breakthrough has to be flushed every time. These filters only slow down the contamination relative to water flow rate. Think Of them as big chromatography columns or frontal analysis columns
- ars 4y agoWouldn't a carbon filter work better then? If I understand them right it will keep the pfas stuck inside itself and not let it diffuse.
- kurupt213 4y agoThe filters are carbon. Every filter has breakthrough. And the filter components themselves are contaminated prior to construction. This stuff is literally everywhere
