E. Project Description
In 2010 and for the duration of the BP oil-spill, Dauphin Island's primary source of drinking water originated from a shallow well aquifer. This aquifer is known to be susceptible to surface contaminants, and extensive testing and protection efforts had to be performed throughout the oil-spill and subsequent cleanup. The integrity of this aquifer, which now serves as the sole backup to Dauphin Island's drinking water needs, remains ill-fated in the event of another disaster such as that in 2010. The BP oil-spill highlighted the risk associated with some of the components of Dauphin Island's water production and distribution system, and these issues must be addressed. Further distressing Dauphin Island's water production capability is that no inter-connections with other utilities are practical. The remoteness of the island constitutes a critical need for long-term sustainability of a primary resource. Planned improvements to find and develop another viable water source must be made, along with interconnection improvements and overall distribution flexibility.
