Through the incorporation of the DPSIR model, the GSAA enables the characterization of broader sustainability challenges and the response function. [...] It is a tool that is flexible and can be adapted broadly, as long as the project team understands the purpose of the approach and makes the effort to adapt it to the specific conditions of the study area. [...] Lastly, resources dedicated to groundwater sustainability assessment projects could be considered as “wasted” if the results of the assessment cannot be effectively communicated to the public and to the decision-makers. [...] The nature of the assessment – broad or narrow – and the issues being examined will inform the make-up of the team. [...] The pilot projects noted that framing the groundwater issues and the indicators into the DPSIR framework can increase the complexity of the assessment.
