CONSTITUENTS

Any of the chemical substances found in water. Typically, measurements of such constituents in sampled drinking water may consist of Total Dissolved Solids (TDS), Hardness (concentrations of Calcium and Magnesium, specifically), Sodium, Potassium, Sulfate, Chloride, Nitrate, Alkalinity, Bicarbonate, Carbonate, Fluoride, Arsenic, Iron, Manganese, Copper, Zinc, Barium, Boron, Silica, as well as other physical characteristics and properties such as water color, turbidity, pH, and electro-conductivity (EC). (As an example of constituents and their acceptable levels for drinking water, see Appendix D-5, Nevada Drinking Water Standards.)
