Where’s the Lead?

In fall 2022, UNC’s Environment, Health and Safety department began testing water fixtures for lead in University buildings. As of mid-February, EHS, with help from student volunteers, had tested 3,022 fixtures — sinks, drinking fountains, ice machines and other sources — in 232 buildings and found 443 water sources had some trace of lead. More than 85 percent of all water fixtures tested negative.

Green pins indicate no tests found lead in a building’s water fixtures. Yellow pins show where EHS found at least one fixture had up to 15 parts per billion of lead, the level at which the Environmental Protection Agency requires public water utilities to take action to remove the lead from water. Red pins are buildings that had at least one test that showed 15 ppb or more in the water. UNC is not a public water utility and receives its water from the Orange Water and Sewer Authority. This map will be updated as EHS posts additional test results. To access EHS’ database of test results, go to
