All five active wells have potasium hydroxide added for corrosion control. This adjusts the final pH and alkalinity. Sodium hypochlorite (chlorine) is added for disinfection. We carefully monitor the amount of chlorine, adding the smallest quantity necessary to protect the safety of your water without compromising taste. AquaMag, a blended polyphosphate corrosion inhibitor, is injected into the water to sequester iron and manganese; it also helps to protect the lining of the water mains.
