The WHO and HOW of Diver Data

Our new blog series to inform, educate, and share the benefits of capturing your data with a Van Essen Instruments’ Diver.

Who Uses Diver Data & How is Diver Data Used?

By Harry Samby

Over the last several weeks, we all panicked to some extent about COVID-19 crisis. Grocery store shelves are depleted of goods like toilet paper and hand sanitizer. Schools are closed, offices employees are work from home.

Many of us may be in self-quarantine, however, that does not mean we can’t stay in touch. We, as a team, want to connect with you through this blog series featuring our premier suite of Diver datalogger products and services.

Who uses Diver data?

At Van Essen Instruments, groundwater is our business. We offer instrumentation for recording water level and water quality measurements. This data is stored in non-volatile memory for continuous measurement and data collection without having the technicians go on the site for pulling samples repetitively. We support a range of clients from engineering companies, drilling and energy companies, environmental consulting, land developers/construction, oil & gas, governmental/regulatory bodies such as ministries and conservation authorities, and mining companies. Our global client network uses Diver data for diverse applications.

Diver Data Applications

Long-term Water Level Monitoring

  • Diver dataloggers are ideal for long-term or continuous monitoring of groundwater levels. Long-term, systematic measurements of water levels provide essential data needed to evaluate changes in water resources over time, for predictive modeling, and effective monitoring of ground-water management plans.

Aquifer Storage & Recovery (ASR)

  • ASR is a water resources management method for storing water underground during wet periods and recovered when needed during dry periods. Continuous water level and water quality monitoring can help to develop and refine ASR techniques.

Groundwater Extraction from Pumping

  • Pumping tests are a reliable way of determining representative mass hydraulic conductivity of an aquifer. It is important to monitor and understand the groundwater levels prior to drilling any wells that will have significant drawdown. The Diver data collected by monitoring groundwater can be used to determine the amount of groundwater that can safely be withdrawn.

Land Development

  • The urban development project has a huge impact on the groundwater level as it causes water to run off much faster than it would normally.  This leads to reduced charging of the underlying aquifer. Effective groundwater monitoring is the best way to protect the local community, ensure a dependable and affordable groundwater supply, and protect the quantity available for future use.

(De)Watering of Mines

  • Successful dewatering requires a hydrogeological assessment of the mine site. Developing a mine below the groundwater level presents many challenges. Poorly controlled groundwater will have negative impacts on the safety, efficiency, and economics of mining operations. Groundwater investigations such as Installation of the monitoring well and Pumping test play a key role in the development of mine dewatering systems.

Wetlands Monitoring

  • Wetlands are under threat from a variety of human-induced changes to their hydrology. An understanding of wetland hydrology and hydrogeology, water level management and monitoring of change has become essential to restore wetlands. the conductivity of water bodies such as ponds may be monitored to warn if the salinity is in danger of falling outside of the tolerable range for certain water species.

Salt Water Intrusion

  • Salt water contamination in the coastal aquifers has resulted in the closure of many groundwater supply wells due to excessive groundwater pumping. Thus, continuous groundwater management plans must be in place to account for potential changes in water quality that might occur because of saltwater intrusion by monitoring freshwater interfaces in coastal communities to help protect against saltwater intrusions.

Remediation & Landfill Application

  • Groundwater contamination typically forms a “plume” that moves outward and downward into surrounding and underlying aquifers. Landfill plumes may contain dissolved carcinogens, volatile organic compounds, and ions such as sodium, calcium, iron, sulfate, chloride, which makes landfill leachate electrically conductive. Acids dissolved in water release hydrogen ions into a solution, which also enhances electrical conductivity.  The change in electrical conductivity of polluted groundwater can be detected with Diver datalogger.

Apart from the above, Diver dataloggers are also being used for the following applications; watershed, drainage basin, and recharge area studies, storm water run-off monitoring, wellhead protection area (WHPA) studies, predictive modeling and compliance.
