This dataset contains groundwater monitoring data collected from monitoring wells across 10 districts in Malawi between 2024 and 2025. # Malawi Groundwater Monitoring Time-Series Dataset (2024–2025) This dataset contains groundwater monitoring data collected from monitoring wells across 10 districts in Malawi between 2024 and 2025. The data were captured using automated data loggers installed in monitoring wells and were collected and managed by BASEflow. The dataset provides time-series measurements of key groundwater parameters, enabling detailed analysis of aquifer behavior across multiple geographic locations. Variables Included - Date – Date of measurement - Waterpoint Name – Name of the monitoring site - District – Administrative district where the monitoring well is located - Latitude & Longitude – Geographic coordinates of the monitoring well - Source – Data collection method (automated data logger) - Water Level – Groundwater level measurement (typically meters below ground level, depending on installation reference) - Temperature – Groundwater temperature (°C) - Conductivity – Electrical conductivity (µS/cm), indicating dissolved ion concentration and groundwater quality characteristics The use of automated loggers ensures high-frequency, consistent, and reliable measurements suitable for time-series analysis and hydrogeological assessment. 1. **Purpose and Use Cases 1. Groundwater Resource Monitoring** - Tracking spatial and temporal groundwater level variations across districts - Assessing seasonal recharge and depletion patterns - Identifying long-term aquifer trends 2. **Water Quality Surveillance** - Monitoring conductivity trends as a proxy for salinity and mineralization - Detecting potential contamination or quality shifts 3. **Climate and Drought Analysis** - Supporting drought early warning systems - Evaluating groundwater resilience to climate variability 4. **Infrastructure Management** - Informing borehole design and pump installation depths - Supporting preventive maintenance planning - Assessing borehole performance over time 5. **Hydro …
