Groundwater Monitoring for Water Management

by HERON Instruments Inc.     based in Dundas, ONTARIO (CANADA)

Fresh water is one of the planets most critical resources essential to all land based life It is also one of the planets most rapidly diminishing resources. Conservation and protection of existing supplies and the rehabilitation of degraded sources are one of the most urgent problems facing humanity today.

Air monitoring equipments for soil contamination monitoring

by Gradko International Ltd     based in Winchester, UNITED KINGDOM

Previous land uses or accidental spills can result in Volatile Organic Compound (VOC) contamination of soils. Volatile and semi-volatile compounds can then permeate through the soil and may persist for several years. This contamination can be traced and measured using our Soil Probes in conjunction with our VOC sorbent tubes. Soil probes are also useful in checking the effectiveness of remediation actions. This monitoring technique provides a cost-effective identification of hazardous gases.

Data analysis and visualization tools for monitoring well decommissioning

by C Tech Development Corporation     based in Henderson, NEVADA (USA)

Contaminated groundwater sites worldwide are engaged in regular sampling of monitoring wells at a typical cost of $1,500 per well-sampling event. On most sites, many wells are redundant or geostatistically insignificant and can be decommissioned.
EVS-PRO and MVS`s Well Decommission module analyses all available data and quantifies the impact on site assessment quality associated with removing each well. The impact of removing a well is quantified in terms of its impact on the geostatistical plume extent.
During remediation plumes are shrinking and may drift. This can necessitate decommissioning of some wells and adding new wells. C Tech`s well decommissioning and DrillGuide© technology provide the tools to properly monitor and guide the remediation efforts at the lowest possible cost.

Data analysis and visualization tools for groundwater modeling

by C Tech Development Corporation     based in Henderson, NEVADA (USA)

Groundwater and Solute Transport modeling is a sub discipline of environmental sciences with unique needs. Modeling has long utilized 3D simulations, but the ability to visualize the results has lagged far behind the simulation technology. EVS-PRO and MVS have long offered professional level presentation tools worthy of the current state-of-the-art in modeling, and EnterVol now opens that door to GIS professionals around the world. Visualization of groundwater and solute transport modeling results can be performed from third party modeling systems such as USGS MODFLOW, MT3D, GMS©, Groundwater Vistas and Visual MODFLOW© using C Tech’s tools to convert these modeling outputs into EFF format. In conjunction with Lawrence Livermore National Laboratory and IT Group, C Tech performed the visualization and animation of the output from a Groundwater Vistas MODFLOW and MT3D99 simulation of a large industrial complex in the central valley area of California.  This site exhibits highly channelized flow which is evidenced by the flow paths. Note that flow in the lower aquifer crosses underneath the upper channels at about 30 degrees!

Ground Penetrating Radars (GPR) for Archaeology

by Transient Technologies LLC     based in Kyiv, UKRAINE

In archaeology using GPR you can process considerable areas of planned excavations. Therefore, the needed excavation area can be substantially reduced. Time and financial costs reduce as well. Examining historical buildings GPRs allow to find hidden rooms, spot areas of demolition in the object structure. What is remarkable, you can make a noncontact research with GPR (e.g. above ground surface).

Monitoring of VOCs in Porewater

by SORBISENSE     based in Tjele, DENMARK

Monitoring VOCs in porewater in the unsaturated zone is now possible.

Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.

The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.

A simple construction with multiple options

The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.
