Several social studies of water highlight the mutual shaping of water and society. Recent interdisciplinary approaches aim to account for and ultimately serve the groundwater–society interactions. This chapter’s goal is to introduce the readers to socio-hydrology, and particularly socio-hydrogeology, as well as to the hydrosocial literature. Conceptual frameworks and cases are presented for each of these bodies of literature, in order to highlight the difference of these two ways of thinking “interdisciplinarity” in groundwater context. Several case narratives also draw attention on the biases that may occur from unquestioned power asymmetries, discourses, and knowledge, in the pursuit of sustainability. The specificities of the complex enmeshment of surface water, groundwater, and social and political issues around groundwater use and governance make the case for bringing together physical and human (critical) geographies, seeking complementarity and cross-sectoral exchanges and actions.
