Abstract |
A pilot plant study was conducted to evaluate the effects of household ion exchange softening on the leaching of metals from home plumbing materials. Phase I was conducted using a finished tap water having a hardness of 10 mg/L (as CaCO3) and a pH of 9.1 and Phase II was conducted using a ground water having a hardness of 300 mg/L (as CaCO3) and pH around 7.3. The pilot plant systems consisted of two pipe loop systems, each system having duplicate loops of lead pipe, copper-solder pipe, copper tubing, and brass faucets. One pipe loop system was used as a control system and was fed the source water and the second system was the test system and fed the same water softened with a houshold ion exchange water softener. Pilot plant operation consisted of an intermittent water flowing period followed by a standing period each day. After a standing period, water samples were collected from each loop and faucet to determine the amount of metal leaching from the loops and faucets. Considering the metal leaching data as a whole, the ion exchanged softened water did not show a pattern of higher metal leaching from the pluming materials, nor did the water softener have a detrimental effect on the significant water quality parameters that influence metallic solubility. |
