Water Quality Parameters: Conductivity & Hardness : …
Both of these metals (that’s right: calcium is a metal!) carry an ionic charge of 2+, thus making them multivalent ions. While “hard water” (>320 mg/L) might cause scaling or the build up of white precipitates on faucets, pipes and other water fixtures, it is not a human health concern and hardness, particularly the calcium fraction, decreases the toxicity of most metals in solution
