In October 2023, potentially cancer-causing chemicals, PCBs, were found in Poe Hall, North Carolina State University's education and psychology building. Since the closure, WRAL 5 On Your Side has received 215 reports of cancer cases in people who worked or studied in the building.
Many of the people who reported illnesses to 5 On Your Side have expressed frustration with N.C. State leaders, saying the university was slow to act and not responsive to their concerns.
Other WRAL Top Stories
5 On Your Side's year-long investigation into Poe Hall has prompted change and action from N.C. State.
A week after 5 On Your Side reported that N.C. State was no longer participating in a federal health investigation, the school of education faculty passed votes of no confidence against N.C. State’s Chancellor Randy Woodson and Vice Chancellor and Provost Warwick Arden.
After 5 On Your Side's report in February, N.C. State reversed its decision and is now working with federal health investigators.
Despite the university's efforts to keep independent investigators out of Poe Hall, an agreement was eventually reached. In July, outside experts were finally allowed inside Poe Hall to conduct their own testing.
In November, a group of local attorneys told WRAL News that they represent hundreds of people who believe Poe Hall gave them cancer or other illnesses. They say they're planning to take legal action against N.C. State, which is the owner of the building, and Monsanto, the manufacturer of the PCBs.
Here's everything we know so far about the Poe Hall investigation at North Carolina State University.

Why did NC State close Poe Hall?
N.C. State announced in November 2023 that Poe Hall would close after testing in October 2023 unveiled the presence of PCBs in the building.
What are PCBs?
Polychlorinated biphenyls, or PCBs, are cancer-causing chemicals that do not break down easily and can be found in the air, water and soil.
PCBs are essentially forever chemicals. They were used in building materials because they are pressure and fire resistant. Experts say most buildings built between 1950 prior to a ban in 1979 have PCBs. Unless the PCB materials were actively removed, PCBs remain in many buildings today since the chemicals don’t degrade.
How do PCBs affect human beings?
People exposed to PCBs in the workplace may experience irritation of the nose and lungs, gastrointestinal discomfort, depression and fatigue and changes in the blood and liver, according to the state.
PCBs are considered a probable carcinogen and linked to several types of cancer.
How are PCBs detected?
PCBs are invisible and detected only through extensive air, dust and surface sampling.
Unlike asbestos, PCBs can affect a person even if they’re not disturbed – thanks to their ability to spread from walls and surfaces to the air. But not all buildings that were built with PCBs have this problem. The only way to know is to test. There’s very little existing regulation that requires PCB testing. In most cases, you only have to test if you think there may be a PCB problem.
How do you get rid of PCBs?
PCBs can only be removed through professional removal.
What did the Poe Hall test results reveal?
N.C. State's preliminary PCB testing results revealed concentrations of PCBs in Poe Hall were 38 times higher than what the EPA deems unsafe for humans. Much of the PCB contamination was found in the HVAC system at N.C. State's Poe Hall.
Five reports, based on tests done in October 2023 and November 2023, indicated varying levels of PCBs in the HVAC system and on surfaces inside Poe Hall.
After NCSU closed Poe Hall, Geosyntec Consultants took 14 air samples and 67 surface samples, searching for PCBs inside Poe Hall.
Geosyntec’s testing occurred with the HVAC system turned off at Poe Hall. They recommended turning on the HVAC system to do more air and surface wipe sampling after bulk samples are analyzed.
Experts said the tests used were not sensitive enough to gauge exactly how contaminated Poe Hall is.
"I have major problems with the method of analysis," said Dr. David Carpenter, director of the Institute for Health and the Environment at the University of Albany.
Carpenter analyzed the report and said the fact that Poe Hall's HVAC system has been off since November distorts the view of what's going on.
Second round of testing reveals HVAC as source of PCBs in Poe Hall
A second round of tests in North Carolina State University's Poe Hall has identified a gold insulation sealant found in the HVAC ducts as the primary source of the PCBs.
The report said the 17 air samples taken showed PCB concentrations, albeit below the EPA recommended exposure levels for evaluating PCBs in school indoor air.
Dr. David Carpenter, director of the Institute for Health and the Environment at the University of Albany and an expert on environmental causes of human disease, took issue with the fact that the tests were only designed to detect certain PCBs, although there are 209 different types of the toxin.
Independent experts have told WRAL many times that an adequate test for a building the size of Poe Hall would require 1,000 samples to really understand where the chemicals were coming from and how people were being exposed.
Will more testing be done?
In July, new testing of Poe Hall began. And this time independent testing will be allowed.
Attorneys working on behalf of those who developed cancer after spending time in a university building made a deal with N.C. State: The university would allow them to conduct their own testing of the building, and in exchange, the results of the testing would be confidential.
The resolution ended a four-month-long fight to get into the building. Spearheading the battle was Darren Masier, a former N.C. State graduate student who petitioned the court to gain access to Poe Hall after the university refused to allow large-scale independent testing of the building.
Dr. Masier’s attorneys petitioned the court, arguing N.C. State was "delaying justice" by not allowing alumni and employees, like Masier, to have their own investigators test Poe Hall. The testing conducted by the private consulting firm N.C. State hired to investigate PCB exposure in Poe Hall was insufficient, Masier's attorneys argued.
N.C. State appealed the judge’s decision to allow independent testing, arguing the issue belongs in a separate court that handles workers' compensation claims.
After a lot of back and forth, N.C. State and Masier's attorneys came to an agreement. In July, outside experts were finally allowed to conduct independent testing of Poe Hall.
For seven days, experts took samples trying to figure out the level of PCB contamination throughout the building.
Results will take about a month to get back.
We're also awaiting the results of the NIOSH's Health Hazard Evaluation of Poe Hall. N.C. State said the results are expected sometime in the fall semester.
Were any other NC State buildings tested for PCBs?
WRAL has been investigating PCBs discovered inside Poe Hall for nearly a year and has now uncovered nearly two dozen other campus buildings contaminated with the same chemical.
In total, 22 N.C. State buildings tested positive for PCBs inside, outside or both since 2017.
The cancer-causing chemicals have been detected on the outside and/or inside of dorms, a library and classroom buildings.
One of the places where PCB levels were found above EPA hazardous waste levels indoors, was Gold Residence Hall in 2019. Records also show the inside of Turlington Residence Hall and five other buildings have also tested positive for PCBs at varying levels.
Metcalf, Bowen and Carroll residence halls were among the 20 buildings where PCBs were detected on the outside.
The following buildings at N.C. State tested positive for PCBs:
- Holladay Hall
- Nelson Hall
- 111 Lampe Drive (formerly) Daniels Hall
- Mann Hall
- Ricks Hall
- NC State University Greek House 7
- NC State University Greek House 8
- Page Hall
- Bowen Hall
- Caldwell Hall
- Carroll Hall
- Gold Hall
- Metcalf Hall
- Tompkins Hall
- Turlington Hall
- DH Hill Library
- Harris Hall
- NC State University Greek Houses 11 (demolition project)
- 207 Oberlin Rd (demolition project)
- 209 Oberlin Rd (demolition project)
- Poe Hall
- Scott Hall

How many people associated with Poe Hall have cancer?
By early February, WRAL 5 On Your Side had received 40 reports of cancer in people who spent time at Poe Hall, including several deaths. By June, 5 On Your Side received more than 200 total reports of cancer cases in people who worked or studied in Poe Hall.
In most cases, 5 On Your Side received new reports of cancer with each story published. Hundreds of sources told WRAL News they received no notification from NCSU about the situation at Poe Hall.
Are the number of cases a statistical anomaly?
It is up to local state and federal health departments to investigate and determine cancer clusters.
Based on 5 On Your Side’s investigation, more than a third of the reported cancer cases are breast cancer. In 2022, the rate of diagnosis of breast cancer in Poe Hall was three times higher than the rate of diagnosis in Wake County, where N.C. State is located.
What health investigations are happening regarding Poe Hall?
After months of WRAL investigations, the Centers for Disease Control and Prevention is now working to determine if there is a connection between PCBs in Poe Hall and employee cancer cases.
In October, WRAL News exclusively obtained a letter indicating that the federal government plans to investigate a potential cancer cluster at the building. The investigation, led by the NIOSH, specifically focuses on workers who were exposed to PCBs in Poe Hall.
"We are taking action to understand the occurrence of cancer among North Carolina State University employees who worked in the building," wrote Jessica Rinsky, an epidemiologist with the U.S. Department of Health and Human Services.
Rinsky asked the state of North Carolina to cross-reference Poe Hall employees with the state’s cancer registry and provide local cancer data to determine if an excess of "specific cancer types" occurred among workers in Poe Hall.
The move marks a new step in the federal government's ongoing investigation into the safety of workers at Poe Hall – now taking a focused look at cancer rates and diagnoses potentially linked to the building.
In January, N.C. State University stopped participating in a Health Hazard Evaluation with the NIOSH, an institute within the CDC.
The news was frustrating to the many workers and students who fear they became sick because of the PCBs in Poe Hall.
"If they understood what these women have gone through, what their families have gone through, they could at least act like they care," said a current N.C. State employee who did not want to be named, for fear of job retaliation.
Following 5 On Your Side’s report, N.C. State reversed its decision and re-asked the CDC to investigate.
This came three weeks after lawyers working on behalf of the university told federal health investigators that they did "not need additional help."
What is a Health Hazard Evaluation?
A Health Hazard Evaluation (HHE) is a free and independent investigation by the CDC's National Institute of Occupational Safety and Health (NIOSH) to identify workplace hazards and make recommendations to protect employees’ health.
The final report from the HHE can make a determination about the potential effects of PCBs found in Poe Hall, but the NIOSH does not have the authority to require N.C. State to take any particular action.
On Aug. 29, Maimone said N.C. State gave NIOSH investigators everything they wanted three weeks earlier. From that point, Maimone said results would take about two months to come back.
"I would expect that sometime in the fall semester we would get those results," Maimone said.
Is NCSU collecting health information?
No, the university is not collecting health information despite the fact that more than 200 people associated with Poe Hall have reported cases of cancer. NCSU remains focused on testing the building environment of Poe Hall.
Many people who reported their cancers or illnesses to N.C. State told WRAL that they never heard back from the university. So they began reporting cases of cancer and serious health issues to 5 On Your Side. N.C. State confirmed with WRAL News that it's not collecting health information.
"N.C. State is not formally collecting information on health conditions..." the university said.
If you have a complaint about Poe Hall and N.C. State, please contact WRAL 5 On Your Side.
Did the PCBs in Poe Hall cause these cancer cases?
Woodson maintains he is unable to comment on specific health issues, such as cancer, until the university-sanctioned building investigation is complete. That messaging has proved frustrating for hundreds of people who spent time in Poe Hall and want more concrete health information.
Dr. Zack Moore, state epidemiologist with the North Carolina Department of Health and Human Services, said it's very difficult to establish cancer clusters – particularly when you're talking about a single building versus an entire community.
What are the legal challenges in this situation?
Attorneys working on behalf of the former student, Darren Masier, argued the testing conducted by the consultants hired by N.C. State to investigate PCB exposure in Poe Hall was insufficient.
In light of the decision, N.C. State was told it had 30 days to turn over documents related to Poe Hall and let the outside experts into the building. Less than two weeks later, the university appealed the decision, meaning outside experts cannot enter Poe Hall.
In June, a panel of appellate court judges ruled that Masier’s team could test Poe Hall but could not take depositions. Later that month, N.C. State appealed to the state supreme court and is now asking the court to put in place a full stay on any pre-suit discovery, including testing and depositions.
An agreement was finally reached in July, ending a four-month-long fight to get into the building. Outside experts can get into Poe Hall at North Carolina State University to test for cancer-causing chemicals known as PCBs, according to an agreement between N.C. State and attorneys for Dr. Darren Masier filed in court.
Did NC State know about PCBs in Poe Hall prior to 2023?
Records show N.C. State knew of PCBs at Poe Hall since 2018.
Records released to WRAL 5 On Your Side by North Carolina State University revealed that tests showed the presence of PCBs on the exterior of Poe Hall.
According to the 2018 report from Matrix Health & Safety Consultants, LLC, caulk samples collected on the exterior of Poe Hall showed PCB levels up to 17,000 parts per million (ppm). PCBs in excess of 50 ppm are considered hazardous special waste, according to the EPA. That means the levels of PCBs found in Poe Hall in 2018 were 340 times higher than EPA guidelines.
WRAL News asked N.C. State if additional interior testing was conducted in 2018 in light of the detection of PCBs in the exterior caulking.
"To our knowledge, no health concerns were expressed related to the renovation, and there was no indication from consultants doing the outdoor testing that indoor testing was needed," said Mary Cole Pike, a spokesperson for N.C. State.
Did NC State ignore employees' complaints and concerns about Poe Hall?
A former NCSU worker and worker, at the time, battling breast cancer said she notified her direct superior about multiple breast cancer cases in Poe Hall. She said nothing was done.
Faculty battling breast cancer and working in Poe Hall reported environmental concerns to the department of labor, EPA and university leaders.
How quickly did NCSU react to health concerns in Poe Hall?
In an email given exclusively to 5 On Your Side, one N.C. State administrator said he hit "dead ends" a couple of times while trying to alert the University’s Environmental Health and Safety department about potentially concerning rates of cancer. Memos from the CDC show a federal health investigation stalled for months as they waited for the go-ahead from N.C. State.
Emails obtained through public records requests and sources show that N.C. State University delayed the ability of federal agencies and the university to address Poe Hall. Records show the EPA and an N.C. State administrator had difficulty reaching university leadership regarding Poe Hall for several weeks.
Emails from the EPA reveal that the agency learned about the closure of Poe Hall from WRAL News. In one email, sent weeks after Poe Hall closed, an EPA PCB expert asked two university administrators: "Is there an N.C. State contact to discuss this situation? I still have not heard anything from the university."
Records show the email was sent to Amy Orders, N.C. State’s senior director of emergency preparedness and strategic initiatives, and Robert Segura, the university’s director of environmental health and safety.
NCSU said it is now cooperating with the EPA and CDC.
We asked Woodson about the breakdown in communication between N.C. State and the EPA.
"I’m not going to answer that," Woodson said.
Woodson eventually said he didn’t engage with the EPA.
Another email from the EPA showed that an EPA employee was interested in visiting Poe Hall, but the agency confirmed that visit never happened.
When asked why N.C. State has not let agencies like the CDC, EPA or independent investigators into Poe Hall to test the building and assist in learning what students and employees were exposed to, the chancellor said Poe Hall is university property.
"We’re the building owner. It’s critical for us to evaluate the building and understand what the nature of the building is," Woodson said.
In July, the university finally agreed to allow outside experts to test Poe Hall.
How do NC State workers and alumni feel about the university’s handling of Poe Hall?
Many people have been critical of NCSU's response, characterizing it as slow and coldhearted.
In February, department of education faculty passed votes of no confidence against N.C. State’s Chancellor Randy Woodson and Vice Chancellor Provost Warwick Arden. The move was purely symbolic – but rare.
Referencing Woodson, the committee wrote, "Due to his mismanagement of the Poe Hall PCB contamination and cancer cluster issue, the faculty of the College of Education at North Carolina State University no longer have confidence in the leadership of Chancellor Woodson."
The results of the vote are as follows:
Chancellor Randy Woodson
- Votes of no confidence: 54%
- Votes of confidence: 25%
- Abstained votes: 22%
Executive Vice Chancellor and Provost Warwick Arden
- Votes of no confidence: 58%
- Votes of confidence: 17%
- Abstained votes: 25%
Dean of the College of Education Paola Sztajn
- Votes of no confidence: 49%
- Votes of confidence: 35%
- Abstained votes: 15%
WRAL News later discovered that N.C. State re-requested its investigation of Poe Hall just hours after the vote of no confidence against Chancellor Woodson.
Woodson announced in July that he will retire at the end of the 2024-25 school year. This comes after more than 210 people who worked or studied in Poe Hall reported to 5 On Your Side that they developed cancer after spending time at the university building.
What is the university doing to help those who spent time in Poe Hall?
PCBs can be detected through a blood test. Several N.C. State students have told WRAL 5 On Your Side that they’ve been unable to obtain such a test through the campus health system.
When asked if the university would consider partnering with a group that could test for PCBs, Woodson said that consideration would come after the National Institute of Occupational Safety and Health completes its investigation into Poe Hall. The CDC told WRAL News that a typical investigation takes 6 to 12 months to complete.
"At this time, the university is not offering health testing or reimbursement for health testing related to Poe Hall because we're still in the evaluation phase of the building's environment," Woodson said.
Is NC State going to test other buildings on campus?
Despite calls from workers and students, N.C. State leadership told WRAL News it has no plans to test other buildings for PCBs unless the building is about to undergo renovation and PCB presence is suspected. This is in accordance with EPA guidance, which suggests that building materials suspected to contain PCBs be directly tested for their presence and removed if renovations are planned.
In September, WRAL discovered that 22 N.C. State buildings have tested positive for PCBs since 2017.
What's going to happen to Poe Hall?
Charles Maimone, N.C. State executive vice chancellor for finance and administration, said in September that the building will essentially be stripped down to its skeleton structure.
He relayed that N.C. State’s engineering analysis found that the structure of Poe Hall is sound – and by not tearing everything down and starting over, the university will save $13 million and about a year of construction time.
He said it will take about three years to rebuild.
"Once we start deconstruction of the building, to rebuild it is three years," Maimone said during the virtual meeting about the timeline after permission and funding is obtained.
What’s needed now, according to Maimone, is permission and money from the North Carolina Legislature to move forward on the project.
In June, a new budget proposal brought forth by House Republicans said the state could spend as little as $5 million if Poe Hall needs a minor overhaul. But it calls for spending up to $180 million in case the building needs to be fully gutted and rebuilt. However, plans to renovate Poe Hall have stalled in the state Senate.
