News release: UAF police find no bombs after morning threat
Updated Tuesday, Sept. 30, 2025, 2:52 p.m.The University of Alaska Fairbanks Police Department has determined that no explosive devices were present at the buildings mentioned in two Tuesday morning emailed bomb threats. Normal operations at the UAF Troth Yeddha’ Campus in Fairbanks resumed around 11:30 a.m.
Police received the first email early Tuesday morning. The email, which came from an anonymous address, said that an explosive device may have been left somewhere near the Elvey Building on the west ridge of campus.
Police issued an emergency alert and then blocked off access to West Ridge for about 5 hours while they searched the building and nearby outdoor areas. UAF also canceled morning classes on the Troth Yeddha’ Campus as a precaution, and asked employees working on West Ridge to stay home until the police were able to determine it was safe.
During the response to the initial email, another email with nearly identical language was received saying there might be another device at the Rasmuson Library. Police were able to quickly search the library and the areas outside the building and determined there was no bomb.
Investigation of the incident is ongoing. The UAF Police Department is working with state, local and federal law enforcement agencies on the investigation. The emails appear to be fraudulent and are similar to those reportedly received by multiple other universities in the United States this morning.

Sampling, testing ongoing
Updated Friday, Feb. 14, 2025, 4:25 p.m.UAF has established and ongoing testing and flushing plan. That plan includes monthly water testing, typically on the second Monday of each month, which is aligned with guidelines from the American Industrial Hygiene Association.
Flushing of water systems is happening continuously where needed and regularly at the following locations:
Hess Village
UA Museum of the North
Akasofu Building
Murie Building
Two fire hydrants between the Museum and the Reichardt Building
Showers in the following buildings are being flushed daily for 15 minutes:
Duckering
UA Museum of the North
Lower level of the Virology Building
Murie Building
Akasofu Building
Flushing helps decrease water temperatures, maintain chlorine levels and create an environment hostile to the bacteria. During these efforts, people may see workers running faucets and taking samples in campus buildings.
Showers reopen in Usibelli, Akasofu buildings
Updated Friday, Nov. 15, 2024, 4:15 p.m.In mid-October, we informed the campus community that certain showers in the Akasofu and Usibelli buildings were closed after legionella bacteria were detected in water samples. After taking the following actions, UAF has reopened affected showers:
Flushed water lines and fixtures to increase water flow and chlorine levels in affected areas
Installed circulating pumps, which will help maintain optimal levels of chlorine in areas with lower water use
Replaced shower heads in the Akasofu and Usibelli buildings, as well as the nearby Murie Building
Conducted follow-up sampling
Thus far, the efforts are working and all showers on campus are open. UAF will continue to work with Facilities Services, consultants and our water provider on a comprehensive plan. In the meantime, we are continuing mitigation measures.

Water system update
Updated Tuesday, Nov. 5, 2024, 5:30 p.m.Following last month's finding of legionella bacteria in low usage locations in the UAF domestic water distribution system, UAF initiated a proactive testing and treatment plan. Testing results indicate that the flushing and treatment have been effective at reducing the presence of bacteria in locations with low water usage. Testing also confirmed the need for flushing where water sits stagnant. UAF will continue flushing and testing to ensure that the bacterial occurrence remains below action limits.
UAF students, faculty and staff should anticipate seeing Facilities Services personnel continuing to flush water systems around campus and collecting water samples. If and when bacteria are found in ongoing testing, affected fixtures will be temporarily closed for flushing. On weekends, Facilities Services will conduct specialized treatment in specific low-water-usage buildings.
It is important to note that UAF's drinking water remains safe and meets all regulatory standards. We encourage anyone with questions to review our FAQs or contact Facilities Services at 474-7000.
Showers closed in two buildings as precaution
Updated Friday, Oct. 18, 2024, 1:45 p.m.UAF has closed showers in the Usibelli and Akasofu buildings after water in the buildings tested positive for legionella bacteria. Users of the showers in those buildings should use the showers at the Student Recreation Center, which recently tested negative for the bacteria. The water in both buildings, and on the UAF campus, is safe for drinking.
What is Legionella?
Legionella is a bacteria that occurs naturally in the environment and can be found in public water systems. According to the Centers for Disease Control, vulnerable populations may be susceptible to Legionnaires' disease or Pontiac fever if they breathe in small water droplets containing the bacteria, such as those produced in showers. Legionella bacteria does not cause illness when people drink the water and does not spread from person to person.
What actions is UAF taking?
Although no other instances of legionella have been identified on campus, we will be testing the water in our buildings in the coming days. Users may see periodic shower closures on campus while UAF conducts sampling or makes water adjustments. We are also increasing the chlorine levels throughout the campus water system to disinfect the supply lines. The water will still be safe to drink, but users may taste or smell the slightly higher levels of chlorine. Flushing water throughout the system may also cause some slight discoloration. Running the water for 30 seconds should eliminate the discoloration.
What should you do?
If you normally use the showers in Akasofu or Usibelli, you are welcome to use the showers at the SRC until the showers in those buildings reopen. SRC membership will not be required to use the showers. Others on campus can continue to use water normally, but can also use the SRC showers if they prefer.
Where can you get more information?
You can find more information about legionella on the CDC’s website.
When will the showers reopen?
Showers in Usibelli and Akasofu were reopened on Nov. 13. All campus showers are currently open, or will have posted signage if closed periodically.
Is it safe to drink the water on campus?
The disease caused by the Legionella bacteria is not transmitted by drinking water. UAF does routine testing of its water, which shows that the water meets safe drinking water standards set by the government.
Is it safe to shower on campus?
We have closed the showers in the buildings that have tested positive for the Legionella bacteria. Other than the Usibelli and Akasofu building showers, people can use showers on campus. Several other locations on campus have been tested, including the SRC, Harwood Hall and the incoming water from College Utilities. The bacteria was not found in any of those other locations.
How does Legionnaires’ disease spread?
It spreads when someone inhales water droplets that contain the Legionella bacteria. It can also spread if someone aspirates water into their lungs. It is not spread from person to person or via ingesting water. For more information, visit the CDC’s website.
How did UAF discover the bacteria?
UAF tested the Usibelli Building, conforming with lease terms of an organization that leases space in the building. The bacteria in Akasofu was discovered during a research study conducted by a UAF researcher.
What is UAF doing about it?
UAF has an ongoing testing and flushing plan. That plan includes monthly water testing, typically on the second Monday of each month, which is aligned with guidelines from the American Industrial Hygiene Association.
Flushing of water systems is happening continuously where needed and regularly at the following locations:
Hess Village
UA Museum of the North
Akasofu Building
Murie Building
Two fire hydrants between the Museum and the Reichardt Building
Showers in the following buildings are being flushed daily for 15 minutes:
Duckering
UA Museum of the North
Lower level of the Virology Building
Murie Building
Akasofu Building
Flushing helps decrease water temperatures, maintain chlorine levels and create an environment hostile to the bacteria. During these efforts, people may see workers running faucets and taking samples in campus buildings.
What does it mean to flush water lines and fixtures?
It means running water through those systems, either by pumping the water through the pipes or by turning on things like faucets or showers and letting them run for several minutes.
Will the extra chlorine in the water be harmful to me?
No, the additional chlorine in the water is safe and will effectively disinfect the system.
What does increasing chlorine levels do?
Chlorine, when added to water in known concentrations, is a safe means to disinfect the water and kill harmful bacteria including the Legionella bacteria. Flushing the system will bring chlorine concentration levels up throughout the water system. As this water circulates through our water system, it will serve as a disinfectant while still remaining safe for normal consumption and use.
Is there still legionella in the water system?
UAF is conducting ongoing sampling. The most recent test results show that bacteria levels dropped in areas where flushing has happened. UAF is continuing to flush areas with low water use to continue that trend. Because legionella occurs naturally in the environment, it’s not uncommon to find it at low levels in public or residential water systems.
How much of the bacteria was in the water?
Levels varied depending on location, but all levels were below those that are of concern for causing illness in most individuals who are not immunocompromised or at high-risk. UAF is using guidance provided by state regulators to inform our response and ongoing mitigation efforts. You can read the guidance by downloading the PDF “Protocol for responding to the detection of Legionella pneumophila in drinking water distribution systems” that was published in the journal AWWA Water Science.
Does UAF routinely test for legionella bacteria?
No, testing for legionella is not required by state or federal regulations.
Is legionella dangerous?
Most healthy people are not affected by exposure to Legionella. However, in vulnerable individuals the bacteria can cause illnesses like Pontiac fever, which is a mild respiratory infection, and Legionnaires’ disease, which is a type of pneumonia. The CDC has more information about people who may be at increased risk of illness due to exposure.
What should I do if I am at increased risk of illness?
Reach out to UAF’s Environmental Health, Safety and Risk Management department for guidance. You can call them at 907-474-6603 or 907-474-6771.
What if I am sick and think I have Legionnaires’ disease or Pontiac fever?
Legionnaires’ disease cannot be diagnosed solely based on your symptoms. If you are ill, you can contact your medical provider. Students can contact the Student Health and Counseling Center. Your medical provider can discuss with you whether testing and/or treatment is necessary.
What if I still have questions?
If you still have questions, you can contact UAF’s Environmental Health, Safety, and Risk Management department at 907-474-6603 or 907-474-6771 or email UAF-fsdispatch@alaska.edu.
