What kind of water is healthy and good water?

Personally think that safe and nutritious water is good water. Safety means that the indicators of microorganisms and pollutants meet the national standards; Nutrition means that water is rich in trace elements and minerals beneficial to human body. However, it is difficult to define which mineral has much effect, and the controversy about pure water and mineral water in recent years is inconclusive. However, in any case, drinking water must meet the Hygienic Standard for Drinking Water GB5749-2006, which stipulates that the TOC limit must be less than 5mg/L, the COD limit must be less than 3.0mg/L, and the TDS limit must be less than1000 mg/L.
