Network Design Critical To Revealing Groundwater and Surface Water Interactions

Figure source is citation 5

California’s Sustainable Groundwater Management Act of 2014 (SGMA) requires that Groundwater Sustainability Agencies (GSAs) manage groundwater resources to avoid significant and unreasonable adverse impacts on beneficial uses of interconnected surface water1, 2. Surface Water Depletion is one of the six SGMA Sustainability Factors that GSAs and their Groundwater Sustainability Plans (GSPs) must consider and endeavor… Read more »

Tagged water-level measurements provide greater insight into network aquifer characteristics and pumping activity

Wellntel Tags

Wellntel systems collect detailed data on pumping activity, tagging these data to be useful in understanding the groundwater aquifer and the operational characteristics of network wells. Data Tagging The data that can be collected, tagged, and displayed in real time are: the water level in the well during each timed measurement – tagged as Timed… Read more »

Irrigation Management is improved with realtime groundwater-level monitoring

Pumping Activity in an Irrigation Well

The Wellntel Groundwater Information System provides a complete analytics platform – sensors, telemetry, and realtime analytics – that integrate real-time water-supply data with consumptive-use requirements to provide decision support for operational hydrology. As agricultural operations continue to expand in areas where available groundwater supplies are restricted either by lesser saturated thickness or by allocation limits,… Read more »

Pumping Influence In Central Texas Trinity Aquifer Revealed In Real Time

Figure 3

The Comal Trinity Groundwater Conservation District is employing Wellntel technology to create a cost-effective and powerful groundwater-monitoring network that will greatly increase hydrogeologic understanding and science-based resource management. Their network build-out began in October 2018 with 4 wells, scaling to 10 in early 2019. “The plan to establish monitoring wells in the Trinity Aquifer has… Read more »

Wellntel Matches Pressure Transducer Performance

Resulting comparison between Wellntel and Pressure Transducer shows very high correlation between instruments

In a side-by-side comparison with a combination pressure transducer and barometric pressure logger, Wellntel has shown that with proper calibration and “benchmarking,” Wellntel will deliver accuracy and precision on par with much more expensive and complicated instruments. Here are the results of a three-month study conducted by members of the South Benton County Community Groundwater Network,… Read more »

Groundwater insights allow businesses to meet sustainability goals

Wellntel for the Sustainable Businesses

It was once thought that groundwater monitoring would be the exclusive purview of government scientists, agencies and regulators. Wellntel upends that premise by enlisting, teaching and enabling citizens and community groups to themselves become collectors of groundwater data. We’ve seen that businesses are as interested as citizens and communities in sustainability, and need groundwater facts to meet their profit goals, their goals… Read more »

Wellntel at Badger Rock Center finds hydrologic connections

Surface Water and Groundwater Level - Badger Rock Center, Madison, Wisconsin

Wellntel systems at the Badger Rock Center are tracking groundwater and water in storage on the south side of Madison, Wisconsin. Data from the systems help neighbors, gardeners, teachers, students, and facility managers to see connections between rainfall, rainfall collection, pumping for irrigation, and groundwater levels in the shallow aquifer underlying the school, its gardens, and the neighborhood. Recently,… Read more »

Surface water nutrient loads shown to receive significant contribution from groundwater

Warning sign

Dense groundwater-level data – as gathered by Wellntel CGNs – are essential to meet TMDL testing needs Total Maximum Daily Load (TMDL) guides restoration The US EPA’s 303(d) Program of the Clean Water Act assists states, territories and authorized tribes in submitting lists of impaired waters and developing the Total Maximum Daily Load (TMDL) for a… Read more »

As central oversight lessens, neighbors take resilience into their own hands

A reach of the Little Plover River in the Central Sands area of Wisconsin

The need for continuous hydrological data is growing, while the ability of government agencies to collect and interpret these data is flat or declining.

Wellntel data confirm satellite-based groundwater trends

Water levels measured by Wellntel System in California well, 2016/2017

Providing networked data at the level needed to make informed decisions, take action, and manage local groundwater resources This colorful map, developed by the National Aeronautics and Space Administration, provides an important view of the extent and level of drought and wetness in shallow aquifers across the United States. These regional conditions vary seasonally and… Read more »
