Ayobami Oni received the Blue Integrated Partnerships Extra Mile Award for water and environmental research conducted at the 2026 Summer Institute. The award recognizes Oni for developing a heat-tracer device designed to monitor groundwater velocity and direction.
Why it matters
Tracking groundwater movement is critical for identifying potential pollutant migration paths in fragile watersheds. This research provides a localized monitoring mechanism that can assist in water resource management.
The monitoring device uses a heater to generate thermal signals, which are captured by sensors to calculate groundwater flow. The system design incorporates circuit-board engineering and sensor calibration to interpret heat transport.
The players
Ayobami Oni
An environmental researcher and Purdue University graduate with expertise in agricultural and biological engineering.
Blue Integrated Partnerships
An organization focused on collaborative water research and environmental sustainability initiatives.
The details
The device operates by injecting controlled heat into the subsurface environment as a tracer. Sensors then measure how this thermal signal migrates with the water, allowing researchers to calculate velocity and direction using computational fluid dynamics. The development process involved iterative sensor calibration and circuit-board design to ensure precision in varied field conditions within the Río Grande de Loíza watershed.

The Tech Race
Oni's work sits within a growing field of low-cost, sensor-based groundwater tracking designed to outperform older, less precise well-monitoring methods. It follows a research trajectory focused on automating hydrogeological data collection in regions prone to precipitation variability.
This development offers a potential new tool for water resource managers and environmental scientists tracking pollution. Deployment in the field will eventually allow for more accurate mapping of contaminant migration in watershed systems.
The takeaway
The development of low-cost thermal tracer devices marks a shift toward more granular groundwater management. Researchers and stakeholders should look for upcoming field validation reports to see how the device performs against conventional flow meters.
