On 5/20/2008, EPA was notified that the Bridger Valley Joint Powers Board water system was shut down due to an inability to produce water below the 0.3 Nethelometric Turbidity Unit finished water turbidity limit. During the night of 5/19/2008, the system ran out of water in the storage tanks. This led to a loss of pressure in the distribution system, which may cause a net movement of water from outside the pipe to the inside through cracks, breaks, or joints in the distribution system. Since the town of Lyman public water system is a consecutive water system to the Bridger Valley Joint Powers Board water system, EPA is issuing an Administrative Order to the Town of Lyman in order to ensure the protection of public health for residents and water consumers.
