Field Notes
Occasional writing on US drinking water, from the hydrogeologist who built WaterScore.
America's water: a nationwide drinking water dataset
Drinking water data in the US is collected by 51 separate jurisdictions, in dozens of incompatible formats. WaterScore normalizes it into one comparable dataset: ~48,000 community water systems, ~200 contaminants, 1.35 million measurements. Here's what it shows.
Nobody mentions the tap water.
If a hydrogeologist can't tell from a water quality report that the water is dangerous during pregnancy, what chance does anyone else have?
