How we rank the municipalities
Safety (50%): bacteria, heavy metals, nitrates, pesticides — the parameters that matter most for health.
Hardness (25%): dissolved minerals that affect appliances, limescale buildup, and water taste.
Taste & Comfort (25%): chlorine levels, pH balance, turbidity, odour, and colour.
