Groundwater Risk Assessment and Management Strategies
Summary
Groundwater underpins drinking-water supplies, agriculture and ecosystem services worldwide, yet it faces mounting threats from overexploitation, contamination and climate-driven variability. Risk assessment brings together data on aquifer properties, recharge and human pressures to identify zones of greatest vulnerability. Approaches range from index-based methods that rank contamination susceptibility, through process-oriented modelling of flow and transport, to probabilistic frameworks that quantify uncertainty. Management strategies integrate these assessments into land-use planning, abstraction control, contaminant source regulation and infrastructure design to prevent or mitigate adverse outcomes. Early-warning tools and decision support systems increasingly couple groundwater models with meteorological forecasts to anticipate flooding or drought. Adaptive management requires stakeholder engagement and policy instruments that balance supply demands with long-term aquifer health. Recent advances have emphasised high-resolution mapping, integrated surface–subsurface modelling and risk communication to translate complex science into actionable guidance. The global significance of groundwater risk assessment lies in its capacity to inform sustainable resource allocation, protect public health and preserve ecosystem functions in a changing climate.

Technical terms
Aquifer: A subsurface geological formation capable of storing and transmitting groundwater to wells and springs.
Groundwater flooding: Inundation caused by rising groundwater levels exceeding the ground surface or drainage capacity.
Vulnerability index: A quantitative measure of the susceptibility of an aquifer to contamination or external stressors.
Inundation modelling: Computational simulation of water spread over land taking into account surface and subsurface flow.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
