97 - How are Alaska Water Systems Interdependent with Other Infrastructure? A Systematic Literature Review

The provision of clean water services is critical to ensure the vitality of Alaskan communities. Water systems in Alaska operate differently than those in the contiguous US given the arctic climate, remote geography, and unique workforce considerations. For example, some communities rely on water delivered using trucks and many households use traditional sources (e.g., rainwater, ice melt). This unique context reconfigures how water systems relate to other critical infrastructure services (CISs), such as transportation and electricity. For instance, the high energy costs needed to heat water systems in Alaska can exacerbate water insecurity. In another example, some communities with delivered water services can be limited by transportation challenges such as limited connectivity, roadway damage, and reduced visibility during winter weather. While we recognize that water-related challenges in Alaska are often linked to other CISs, it remains unclear how these interdependencies shape services—for instance, which connections are sources of vulnerability? Through a systematic literature review, we seek to understand the underlying network of interdependencies between water systems and other CISs in Alaska. We employ a qualitative content analysis of scholarly literature to identify relevant CISs and how they influence the provision of water services. By enhancing our knowledge about infrastructure interdependencies in Alaska, we develop holistic management approaches that can lead to improved services for end-users. Further, our work identifies key research gaps and opportunities, guiding future efforts to address the complex interplay of CISs in Alaska.
