HydroMetrics - Nitrate GW50
Groundwater Optical Nitrate Sensor
Many countries around the world are in the process of adopting nitrate caps via nitrogen discharge allowances to manage nitrate losses into freshwater bodies and groundwater drinking supplies from agricultural production.
One area that remains unclear is how nitrate losses will be reliably measured to monitor and enforce these limits. Current approaches are principally based on modelling, rather than direct measurement of nitrate losses, as options such as regular physical sampling or real-time sensors are too expensive to be scalable. To address this, Lincoln Agritech has developed a low-cost sensor capable of measuring the concentration of nitrates in groundwater via monitoring wells.
Connectivity is key to data access
Speed of access is important
