What chemicals are added to the water?
All chemicals used at the water treatment facility are approved for use in drinking water. At the treatment plant, suspended and dissolved material is removed by coagulation, flocculation, and settling using polyaluminum chloride.

After filtering, the water is treated with sodium hydroxide to adjust the pH. Polyphosphate is added to sequester metals and help reduce corrosion of household plumbing. Sodium hypochlorite is added to destroy pathogens, and fluorosilicic acid is added for dental hygiene.
