Monitors dissolved petroleum hydrocarbons and gases in groundwater, continuously and automatically. Replaces or supplements periodic groundwater sampling — delivering real-time data on plume stability and remediation performance without repeated field visits. Real time sensor data routinely updates groundwater models for improved risk assessment.

  • What It Measures: LiORA Water Sensor measures CO₂, O₂, CH₄, total hydrocarbons from EC2-EC12, including BTEX, temperature, pressure, and relative humidity. 
  • How It Measures: Uses non-dispersive infrared (NDIR) to detect hydrocarbons and gases dissolved in groundwater. The multi-channel design separates different hydrocarbon types, reducing cross-interference and improving accuracy in mixed-contaminant conditions.  
  • Data & Security: Data is measured, transferred, and securely transmitted every 30 minutes via long-range wireless (LoRaWAN) and stored both on device and cloud platform. 
  • Detection Performance: PHC range: 0–140 mg/L | Resolution: 0.005 mg/L 
  • How It’s Installed: Sensors can be readily deployed in water, including within existing 2” (or greater) monitoring wells.
