Water Quality Testing Program

Water Quality Testing Program

In 2017, Charlotte-Mecklenburg Schools (CMS) launched a proactive water quality program to protect students' and staff's health and safety and ensure learning and teaching in a safe environment in school, not in response to any specific condition or issue. Our goal is to test water quality in all schools.

Six states — Illinois, Maryland, Minnesota, New Jersey, New York and Virginia — have required school districts to test for lead. North Carolina has not required the testing at this time.

Parents are notified before testing at the schools. In addition, parents will be notified should any conditions be found that experts advise may pose serious concerns related to the health or safety of students and staff.

Testing in elementary schools was completed first. Where corrections have been made, they were related to specific fixtures, not the general water supply of any school.

Connect-5 Message

The following is a copy of the Connect-5 that went out regarding the Water Testing Program:

Good evening. This is a message from Charlotte-Mecklenburg Schools. As part of our commitment to providing safe, healthy environments, the district will continue its voluntary water testing that began in the spring. We don’t expect to find significant water-quality issues but we are being proactive to ensure that the water in our pipes, faucets and water fountains is clean and safe. We will conduct water testing at 35 sites beginning Sept. 24 and ending Nov. 14. Your student’s school is among the 35 being tested next. Testing will not disrupt classes; it will be done when students are not in the building. To see when your student’s school is scheduled for testing, you can visit our Water Quality Program on the CMS website or contact your student’s school. This testing is proactive and voluntary to ensure student and staff safety. We look forward to sharing results with you as they become available. You will receive a letter with additional details on the CMS Water Quality Program. Thank you for choosing CMS for your student.

Frequently Asked Questions

Frequently Asked Questions

Why is CMS conducting lead in drinking water testing?

CMS voluntarily conducts the water testing program to ensure safe drinking water within the schools to identify and correct consumption points that show lead and copper concentrations over the EPA (EPA) and State of North Carolina action levels. Current state and federal laws do not require schools, like CMS, that purchase water from a Public Water System to test for lead. However, the Safe Drinking Water Act’s Lead and Copper Rule requires Public Water Systems to sample lead at single-family dwellings. The most typical type of Public Water System is a municipally-owned drinking water utility, which must adhere to the Environmental Protection Agency (EPA) and North Carolina Drinking Water Standards (NC DWS) that regulate the quality of water delivered to the public.

What are the Action Levels for lead and copper?

The CMS water testing program uses action levels for drinking water by the State of North Carolina of 0.015 milligrams per liter (mg/L) or 15 parts per billion (ppb) for lead and 1.3 mg/l or 1,300 ppb for copper, slightly more stringent than the action level from the EPA (the applicable action level for the CMS water testing program). It is important to note that the action levels are not direct measures of health effects; they serve as signals of when to reduce the lead and/or copper concentrations in the water.

What is the action level for lead in school drinking water?
The EPA recommends taking action at a specific outlet when the lead concentration is over 20 parts per billion (ppb). (Note: this is different from the 15 ppb action level required for public water systems).

How can I learn more about lead testing?

Visit this website. EPA drinking water in schools. Several documents are available that detail how to test for lead in drinking water in schools.

Why are the lead action levels different for public water systems and schools?

The two lead action levels differ because of the different problems they seek to detect and the different monitoring protocols used in the two situations. The 20 ppb action level and sampling protocol for lead in schools are designed to pinpoint specific water fountains and outlets that require remediation (e.g., water cooler replacement). The 15 ppb action level and sampling protocol for public water systems are designed to identify system-wide problems and not problems in single outlets (56 FR 26460, 26479; June 7, 1991).

How can lead get into the water supply?

The Public Water System, Charlotte Water, is the water supply to the majority of CMS schools. The potable water pumped to the water treatment plants' water distribution system meets federal and state standards for lead. The lead comes from the pipe and plumbing fixtures that release metal into the water it comes in contact with, particularly those containing lead, such as lead solder, brass fittings, and old fixtures. Lead sources and lead levels vary between buildings and individual fixtures, so it is important to identify and remove lead sources in each building.

What about brass fittings?

A significant amount of plumbing has brass components containing lead. Until 2014, brass faucets and fittings sold in the United States and labeled ‘lead-free’ could still contain up to 8 percent lead. Effective January 2014, the Reduction of Lead in Drinking Water Act specifies that these materials may not contain more than 0.25% lead.

What is a consumption point?

A consumption point is a water testing location where the general public can obtain drinking water or use the water for food preparation. All working consumption points for a school were tested for lead and copper in the drinking water. Example consumption points include food preparation areas, ice makers, nurse’s stations, home economics classrooms, teacher lounges and drinking water fountains, coolers and bubblers.

What schools are sampled as part of the program?

Schools with current or future use buildings constructed on or before 1989 have been identified by CMS as the most at risk. Until 1987, lead and copper-containing pipes, solder, and fittings were widely used during construction in the United States. Therefore, schools built on or before 1989 were prioritized for this program. Additionally, elementary schools were prioritized based on the age of the school population. Children under six years old are at the highest risk for elevated blood lead levels; therefore, schools with elementary programs, including pre-kindergarten (PK-5, K-8 and K-12), were tested.

What do I do if I have questions about the results?

You can contact your school or email at: ehs@cms.k12.nc.us

The lead levels at our school are above 15 ppb (parts per billion). Should we be concerned?

Lead in water measured above 15 ppb does not necessarily mean people will have elevated blood lead levels in their bodies. The 15 ppb is considered an “action level.” When levels of more than 15 ppb were found, CMS took immediate steps to reduce lead in the water by permanently taking that consumption point out of service or replacing/repairing the consumption point. All consumption points repaired or replaced were retested to confirm the lead action level was met before allowing that consumption point to be brought back into service. In addition, the lead level is not a measure of the lead present in the water during continued use throughout the school day. This level was measured when water was sitting in the pipes or water fountain for several hours without being used to get an idea of what the highest level of lead in the water is likely to be.

What are the health concerns from lead exposure?

Young children are most at risk of lead exposure as they are still developing and tend to put objects in their mouths. In children, lead poisoning can cause slowed development, reading and other learning problems, behavior problems, and brain, liver, and kidney damage. Pregnant women can also pass lead to their unborn babies. The only way to know if you or your child has been exposed to lead is to have your health care provider do a simple blood lead test, typically a simple finger stick procedure.
