Hendersonvilles Service Line Inventory, Compliance with EPA's New Lead and Copper Rule Revisions and Improvements

In 1991, the Environmental Protection Agency (EPA) implemented the Lead and Copper Rule (LCR) to control the presence of lead and copper in drinking water. In 2021, the EPA updated this rule, known as the Lead and Copper Rule Revisions (LCRR), which strengthens regulations to better protect children and communities by reducing lead in drinking water. 

The LCRR requires water utilities nationwide to increase tap water testing and create a service line database to identify the presence of lead pipes in water systems, including elementary schools and daycares. Service lines carry water from the public water mains into homes and buildings, with ownership changing at the water meter.

Actions the Utility is taking to reduce lead exposure  

The Hendersonville Water Department is committed to protecting the community’s health by delivering safe water.  We have monitored lead and copper levels in our water since 1991 and have consistently met EPA standards. Learn more about Hendersonville's water quality efforts 

To ensure water quality meets or exceeds all EPA regulations, we regularly test water at our treatment facility and throughout the system. Lead is not present in our water sources or in our drinking water when it leaves the treatment facility and travels through our lead-free distribution pipes. The Safe Drinking Water Act of 1986 banned the use of lead in plumbing materials, therefore homes built before 1986 are more likely to have lead solder, pipes, and fixtures. Lead may enter drinking water primarily through corrosion in service pipes made of lead, or other plumbing materials that contain lead such as through corrosion of lead solder. 

To reduce corrosion, we use best management practices at our Drinking Water Treatment Plant, including adjusting pH and adding a small amount of orthophosphate to create a protective barrier between pipes and water. These practices help minimize corrosion in water lines and household plumbing.  

The full LCRR and Lead and Copper Rule Improvements (LCRI) can be found on the EPA’s website at EPA's LCRR and LCRI page. These revisions aim to achieve a 100% lead service line replacement nationwide within the next 10 years, and we are committed to doing our part.  

Lead is not present in our source water, nor is it in the water coming from the water treatment plant. Lead can come from plumbing materials that contain lead. A few examples of potential sources of lead are older style faucets made with lead, copper pipes with lead solder, and a lead service line. (We currently have no known lead pipes!!) When these pipes corrode, they can lead lead into drinking water. At the water treatment plant we corrosion control methods to prevent pipes from corroding. We use a pH adjustment, and orthophosphate, which binds to pipes to prevent corrosion.The lead pipe on the left is coated to prevent corrosion. The lead pipe on the right without the coating shows the water dissolved the lead from the pipe.

Orthophosphate is a USDA food grade additive. Phosphate is the second most abundant mineral in the human body after calcium. The amount of phosphate in a quart of treated drinking water is 100 times less than the amount found in the average american diet, and it is found in milk and soda drinks. You would have to drink 10-15 quarts of water to equal the amount of phosphate in one can of soda!
