Clean Water for Carolina Kids™ – From Pilot to Program

Faced with a decision many parents have in common—finding a childcare center—RTI senior environmental health scientist Jennifer Hoponick Redmon thought of something many parents would overlook: water quality.

When thinking of ensuring clean water for kids, she was specifically concerned about exposure to lead, which is well known for its negative effects on children’s health. Most water consumers in the United States think that if their water were unsafe, “someone” would warn them. But for North Carolina childcare centers, there is no one to send out the warning. Centers aren’t currently required to test for lead in their water. With no information to verify clean water for kids, there’s also no way to fix it if something is wrong. As more than 250,000 North Carolina children spend much of their day in childcare centers, this lack of information about a crucial safety issue demanded action.

Centers currently only conducted water tests if a child was found to have elevated levels of lead in his or her blood, which spurs the state health department to investigate the cause. Unfortunately, this means that children are often “detecting” lead, even though health effects from lead exposure are irreversible. Lifelong deficits in IQ, behavioral difficulties and more are associated with any lead exposure, so Redmon knew that clean water for kids for drinking and cooking needed to be a top priority.

Redmon’s intuition led RTI to fund Clean Water for Carolina Kids™, a pilot project that tested water in childcare centers across four counties in the North Carolina Piedmont. She combined her environmental health expertise with the expertise of her colleague in laboratory sciences, Dr. Keith Levine, to pilot the first study of childcare water quality in North Carolina. To our knowledge, this is also the first study globally to train childcare administrators as citizen scientists to collect water samples, communicate findings and mitigate the risks of lead in drinking water.

In 2017, the project enrolled more than 100 childcare centers in the region surrounding our headquarters to ensure clean water for kids. RTI staff and parents in central North Carolina were invited to recruit their own childcare centers, knowing the results could help protect their children and other members of their community. The project surfaced alarming results about the prevalence of lead in childcare centers. We found that:

• 97 percent of centers had a measurable level of lead in at least one tap
• 16 percent of centers—about one out of six—had at least one sample that exceeded 15 parts per billion, which is the level at which public utilities are required to take treatment action
• the tap with the most lead in our study, a kitchen sink, had a level of 121 parts per billion of lead, three orders of magnitude greater than any other tap in the same center.

Our study results showed that lead is indeed present in childcare centers, and the level at which it is present varies greatly from tap to tap, even within the same center. Lead enters the water supply through piping and plumbing. Lead levels can vary from one building to the next, or from one faucet to another within the same building, based on a variety of factors. Even if water looks, smells or tastes good, people can still be exposed to lead—it has no color, odor or smell. Even newer buildings and faucet fixtures can have detectable levels of lead. The only way to know for sure is to test it at the tap.

Advanced Laboratory Testing to Ensure Clean Water for US Kids™

With our state-of-the-science advanced laboratory capabilities, we quantified lead down to 0.1 parts per billion (ppb), 30 times lower than lead is detected at most public utilities. This is important because the American Academy of Pediatrics recommends that an enforceable health-based standard is set for lead at 1 ppb, and the U.S. Environmental Protection Agency has a goal for lead exposure in drinking water of zero. To guarantee clean water for US kids, it is necessary to detect lead at or below health-based standards to take necessary steps to get the lead out.

Community Outreach and Citizen Scientists

Citizen science uses public participation to collect scientific data and empower citizens to work with scientists to make progress on a large scientific issue. Using a community-based approach to testing and fixing lead in drinking water ensures that child care administrators, staff, and parents understand the problem and can help take collective action to improve the likelihood of clean water for kids now and in the future. Through this program, child care and school administrators receive standardize guidance to act as citizen scientists and help ensure that their centers are providing lead-free water for children.

Spotlight on Children’s Exposure to Lead

Clean Water for Carolina Kids™ is part of a greater clean water for US kids movement to reduce children’s exposure to lead from drinking water. Redmon and Levine, in conjunction with academic researchers, governmental scientists, children’s advocacy groups, childcare administrators and parents, have banded together based on the belief that children should have access to clean water, and that water itself rather than children’s blood should be tested to prove that the water is safe to drink. RTI has shared study protocols and findings with the state of North Carolina Department of Health and Human Services, the NC Childcare Commission, Duke University, the University of North Carolina at Chapel Hill, and NC Child. Based on the need for testing and feasibility documented in our pilot study, the North Carolina Commission for Public Health is taking steps toward lead-free drinking water in childcare centers by childcare sanitation guidelines for all licensed childcare centers. The new rule was approved in September 2019 and requires childcare centers and elementary schools with pre-K Head Start programs to test water used for drinking and food preparation, to communicate findings to parents, and to mitigate any sources that exceed state action levels.

EPA Grant Supporting Statewide Testing

Under a grant provided by the United States Environmental Protection Agency, we are currently enrolling and testing all open licensed child care centers and pre-Kindergarten Head Start programs in elementary schools across the state of North Carolina.

Roy Award for Environmental Partnership Winner

Our approach to address lead in drinking water at childcare centers and schools was awarded Harvard’s prestigious Roy Award for Environmental Partnership in the fall of 2020. The mission of the biannual Roy Award is to “encourage governments, companies, and organizations to push the boundaries of creativity and take risks that result in significant actions that benefit the environment.” Selection criteria for the award are based on a partnership with at least two different sectors and organizations, innovation demonstrating a leap of creativity, effectiveness in achieving tangible results, significance in successfully addressing a challenging environmental problem, and transferability of the approach to be successfully replicated in other settings to tangibly improve the quality of our environment.

The program also received the Environmental Business Journal Award for Project Merit in 2020 and a Mutual of America Community Partnership Award in 2021.

Clean Water for US Kids™ Moving Forward

The Clean Water for Carolina Kids™ program is dedicated to eliminating childhood exposure to lead in drinking and cooking water at North Carolina child care centers and schools. With additional federal grant funding, we plan to expand the testing program to include voluntary enrollment of family child care homes, followed by voluntary enrollment of elementary schools without Pre-Kindergarten Head Start programs.
