Testing for Legionella bacteria within the garrison began May 14 and will run for approximately three weeks. Water samples are being taken from buildings with boilers of more than 400 liters and have showers. There are approximately 131 buildings identified, including family and unaccompanied housing, schools, clinics, gyms and hotels. Notification letters will be sent out one week in advance of the sampling and results are expected within 14 days after sampling. If there is an issue with a building, notification will go out to residents within a day, and flushing of the system will occur with a follow up sample taken within seven days.
