How do you tell whether the water you drink is safe? Communities routinely check on the quality of their municipal water supplies. If a home or business owner is unsure whether his or her building's supply meets safety standards, a government or private water quality analyst will provide instructions and containers for taking samples, and assess the purity of the water supply. The analyst's report gives numerical values for mineral content, acidity or alkalinity (pH level), contamination, turbidity, total solids, and biological purity, and an opinion on the sample's suitability for its intended use.
