What is a safe calcium level in drinking water?

A safe calcium level in drinking water typically ranges from 20 to 100 mg/L (milligrams per liter). Levels above this range can lead to scaling in Plumbing and may affect the taste of the water, but they are generally not considered harmful to health. The World Health Organization (WHO) suggests that calcium levels in drinking water should not exceed 200 mg/L to avoid potential health issues. However, the acceptable level can vary depending on local regulations and guidelines.
