Abstract : Freshwater is a critical resource to sustain both societal needs and ecosystem services. Although freshwater is a renewable resource that can be replenished through hydrological cycles, increasing demand from existing and new societal needs, including energy system deployments, may exacerbate water-stress. Traditionally, water footprint approach, which sums up consumptive water use along the supply chain, has been the primary method used in life-cycle analyses to account for water use impact (Lee et al., 2019). However, both freshwater supply and demand vary substantially across the United States, therefore impact of water consumption on local water resource should reflect spatial variations in water availability (Xu et al., 2019b).
To enable cross regional comparison of water-stress impact of regional water consumption scenarios, Argonne National Laboratory developed the Available Water Remaining for the United States (AWARE-US) model (Lee et al., 2019). AWARE-US used the global AWARE framework proposed by the Water Use in LCA (WULCA) Working group (Boulay et al., 2018). Argonne improved it by incorporating observed freshwater supply and demand data and refining the spatial scale at the U.S. county level. The AWARE-US model has been applied to evaluate the water stress impact caused by water consumed for the deployment of hydrogen fuel cell vehicles and algae biofuel production in the United States (Lee et al., 2019; Xu et al., 2019a). In addition, because water availability also changes seasonally, Argonne developed a monthly version of AWARE-US model to enable seasonal water-stress impact assessment (Xu et al., 2020). To support easy-access and interactive analysis, we developed an online version AWARE-US model which is publicly available at This report provides a summary of the monthly AWARE-US model, and instructions for using the web-based water stress analysis model. More details regarding the development and the applications of AWARE-US can be found in our previous publications (Lee et al., 2019; Xu et al., 2020, 2019a).
