PFAS “Forever Chemicals:” What to Know for Charlotte

PFAS have gained national attention as “forever chemicals” because they do not break down naturally in the environment or in the human body. They are part of a family of thousands prevalent compounds that have been used for decades and still used in products like waterproof materials, non-stick pans, and fast food wrappers.

Due to emerging and established health risks, PFAS are becoming more regulated and decreasing in industrial uses. However, many regions still face challenges with upstream industrial use of PFAS chemicals (See more under North Carolina resources below). You may hear about them in the news and from municipalities working to address any concerns in their areas.

Fortunately, our region in Charlotte-Mecklenburg has not had these same concerns with PFAS and PFOA in drinking water. At this time, PFAS are considered unregulated contaminants by the federal government, but the EPA is expected to announce the first Maximum Contaminant Level (MCL) for PFAS in spring 2023.

MCLs establish a maximum level for which a contaminant can be present in drinking water and require water service providers to not exceed that level, as per the Safe Drinking Water Act (SDWA), which means that these compounds will be regulated. Another thing to note is that an MCL is a long-term exposure level – 70 years of drinking 2.5 liters of water daily with PFOA or PFOS at the MCL level.

Charlotte Water proactively and voluntarily monitors for more than 70 per- and poly-fluorinated chemicals quarterly and meets or exceeds all drinking water standards. Monitoring results (available on our unregulated contaminants page) demonstrate very low levels of PFAS/PFOA, with either undetectable levels of PFAS or levels of PFAS barely above the detection limit. All detections are within the anticipated 4ppt MCL. To learn more about your water quality, please visit Charlotte Water’s Water Quality Webpages. Additional resources available below.

Charlotte Water Monitoring:
  • The 2013-2014 UCMR3 included monitoring for six per- and polyfluorinated alkyl compounds
  • Charlotte Water had no detections for any of the six per- and polyfluorinated alkyl compounds during UCMR3 monitoring
  • In 2018, Charlotte Water began additional, voluntary monitoring of source water and drinking water.
  • Since 2019, Charlotte Water has been voluntarily monitoring source water and drinking water, on a quarterly basis.
  • Current monitoring includes more than 70 per- and polyfluorinated alkyl chemicals

Remount Repair Updates

February 2022

Charlotte Water Completes Remount Water Main Pipe Break Repair, New Pipe Placed into Service

The newly installed pipe was treated and water quality tests were performed before pipe activation.

(Charlotte, N.C.)  On Monday, February 14, Charlotte Water crews reactivated the section of 36-inch ductile iron pipe newly installed under Irwin Creek near Remount Road bridge, putting the new water main pipe into service. Crews have been working since November 2021 to repair, remove and replace the previous pipe damaged in a break in October 2021.

During the extensive repair, crews replaced more than 250 feet of pipe. Charlotte Water collaborated closely with County and City partners to protect the integrity of the bridge, the quality of the creek, and the safety of the crews working in the complex location. With the pipe repair completed, Charlotte Water crews will continue site clean-up and restoration for the next few weeks. Charlotte Water will continue to evaluate 21,000 feet of the remaining 36-inch pipe for any possible defects. 

“Every day, Charlotte Water routinely repairs and maintains water and sewer pipes across our entire service area,”  says Charlotte Water Director Angela Charles. “It’s important that we are doing all that we can to keep customers’ trust in our ability to provide clean, safe and reliable water service to the Charlotte region.”

In 2021, Charlotte Water installed or rehabilitated more than 66,000 feet of pipe across the water system and invested $395.4 million into capital project improvements.

Updates November 2021

Charlotte Water crews have been removing and replacing the 36-inch water main pipe that was damaged during the Remount water main break on October 18. While work is expected to continue for the next few weeks, here are a few things you should know about this break, and overall pipe leaks and repair.

Fast Facts:

WHAT is the cause of the Remount Water main break?
There are several factors that can cause a pipe to break, including change in temperature, age and external damage. In this case, because it is underground and several feet beneath a creek, it’s hard to determine the exact cause of this pipe break.

WHEN will the repair be completed?
Crews have removed the broken pipe and are replacing it with the new ductile iron pipe. Work is expected to take a few weeks, primarily due to the location, as crews carefully work in the creek and around the bridge.

WHY am I seeing other leaks?
Charlotte Water crews regularly respond to a variety of leaks that are categorized as minor, priority or emergency. We then work quickly to resolve the issue and restore service to customers. Most repairs are on service lines (between the water main under the street and the customer’s water meter). Did you know that under many of our major roads there are multiple water pipes serving different areas of the county?

WHO should I call if I see a leak?
If you see or suspect a leak, call 3-1-1 or 704-336-7600 so that Charlotte Water can quickly dispatch a crew to the location.

WHERE can I go to learn more about Charlotte Water pipe repair and rehabilitation?
Charlotte Water staff are working 24/7 to maintain more than 8,000 miles of water and wastewater pipes. To learn more about a water and sewer improvement project near you, visit the Projects page at charlottewater.org.

Making Water Outages at Critical Care Facilities a Thing of the Past

In order to repair a broken water main, the location of the break has to be isolated by using pre-installed valves. There are 85,547 water main valves throughout our system. In most cases, this process requires us to turn off water access to nearby customers before working on a pressurized main. An inconvenience for some, but for others like critical care facilities, can be a matter of life or death. That is where a new insertion valve comes in.

The valve can be installed on an existing in-service main and allows us to perform maintenance or repairs without shutting down nearby blocks of the water distribution system.

Staff are currently being trained to install these special valves, and have already installed four in critical areas.

The goal is that at least one crew in every one of our four zones is trained on this specialized valve insertion process so that when a repair is needed near a critical facility, we can install the valve and eliminate the need for a water outage.

Labor Crew Chief and insertion valve project manager Delmond Cummings says, “These valves use fewer fittings, meaning less chance of leaks to the distribution system. The hydraulic integrity of this equipment helps reduce turning off residents or community water for extended periods of time for repair. With this training, employees learn new methods and technologies that upgrade/enhance their knowledge and skill level.“

Though we can’t guarantee that a water outage won’t occur during a repair or routine maintenance of our distribution system, we hope that with the addition of these types of valves in our toolkit, we can minimize disruption to our customers.

This is just one of the many ways that our staff are working to improve the resiliency of a system that protects public health and the environment.

  • There were 151 sanitary sewer overflows in our community, a decrease of 11 spills compared to last year.
  • The number of spills per 100 miles declined from 9.2 in fiscal year 2008 to 3.4 in fiscal year 2020.
  • All seven wastewater treatment plants earned Peak Performance Awards from the National Association of Clean Water Agencies.
  • Our staff continue to work strategically to clear blockages and repair wastewater pipes before they cause sanitary sewer overflows.
  • 405.5 miles of wastewater pipes were treated with root control chemicals.
  • 944.5 miles of wastewater pipes or 24% of our system was cleaned.
  • 13.2 miles of wastewater pipe and 264 manholes were rehabilitated or replaced.

Want to do a deeper dive? Visit our website for the full report.

We asked our staff who work in wastewater why they take pride in their job and what they wish the community knew about wastewater treatment. Here is what they said.

Henry Eudy, Wastewater Treatment Plant Manager

“If you take a long look at human history, wastewater treatment is really one of the most important building blocks in the foundation of civilization. Access to clean water is one of our primal necessities just as organisms in general. 

As we grow and advance, we take more and more from the natural world around us. If we don’t take steps to mitigate the effects of our unprecedented success as a species on the basic building blocks that give us life, then we die. 

An advanced human civilization is not possible without wastewater treatment. What we do is a necessity and a lynchpin to civilization. In a way, the rest of the world is built upon our efforts. The rest of the world may not see it that way, but if we look back over our long shared history, our service to mankind is profound.”- Henry Eudy, Mallard Creek Wastewater Treatment Plant Manager

Johanna McHone, Wastewater Treatment Plant Operator

Johanna, Wastewater Treatment Operator at McDowell grew up around some substantial mine waste. That sparked her desire to want to help clean up the earth and then became interested in the wastewater treatment process.

“A wastewater treatment plant is much like a human body in its functions. Some think it’s disgusting, but we all should be grateful there are operators around to do just this. Without us, the wastewater would end up untreated in the creeks, rivers and oceans. Then where would we get water to drink and shower with? Everyone has a purpose in life, nurses, teachers, engineers etc. There are jobs out there I would not want to do, but this is a perfect fit for me. – says Johanna.

Muriel Steele, Water Quality Specialist

“Treatment plants were originally conceived with the express purpose of controlling infectious diseases! Of course, we have since realized and embraced the added benefits of protecting the environment and natural (and downstream drinking) water quality. Pathogen removal/inactivation is something we are doing 24/7/365, even when there isn’t a global pandemic.”- Muriel Steele

You can help reduce sanitary sewer overflows. Do not put grease, fats, or oils in the drain and do not flush wipes. Throw them in the trash instead.
