Groundwater Monitoring Techniques

Measuring groundwater level or depth-to-water is critically important for identifying long and short-term trends, including declining water levels, saltwater intrusion, and aquifer recharge.

Time-series groundwater data is the foundation for groundwater modeling and forecasting that are useful for identifying drought, characterizing groundwater supply availability, and identifying changing groundwater conditions.

Groundwater monitoring techniques range from on-site measurements to modern remote data collection technologies, such as cellular or satellite communication. Water level, temperature, and/or conductivity measurements can be taken manually or a well can be instrumented with a groundwater level logger or CTD logger.

Near real-time data can be collected and automatically integrated into client servers or cloud-based software for access almost anytime. OTT HydroMet offers multiple level loggers and remote data transmission options to save time and resources spent in the field.

Aquifer Monitoring Around the Northern Texas Panhandle

Aquifer Monitoring Around the Northern Texas Panhandle

With 95% of local water from the Ogallala aquifer going to crop irrigation, this Texas team needed data on their groundwater resources. Read about how they used 37 monitoring wells with IRIDIUM® telemetry to send data into an online interactive map with near real-time groundwater data to share with the district.
