HARD WATER MAY BE TIED TO HIGHER LEAD READINGS
Water Utilities Report High Lead Tap Readings With All Copper & Plastic Services
Research shows that lead can adhere to calcium deposits in copper pipes, particularly if the calcium buildup is significant; this is because the rough surface created by the calcium deposits provides more points of contact for lead particles to attach to, increasing the potential for lead contamination in the water flowing through the pipe.
Hydro-jetting, steam shocks, and abrasive blasting have been used to remove mineral deposits from water services, but more research is needed to enure water service lines are lead-free.
