groundwater analysis Applications

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 and animate the results has lagged far behind the simulation technology. EVS-PRO, MVS, and EnterVol offer professional level presentation tools worthy of the current state-of-the-art in modeling. Visualization of groundwater and solute transport modeling results can be performed with all versions of C Tech’s software except for EVS for ArcView. EVS-Pro, MVS, and EnterVol are particularly well suited for animation and visualization of earth science modeling results from third party modeling systems such as USGS MODFLOW, MT3D, GMS©, Groundwater Vistas© and Visual MODFLOW©. Both combine animation capabilities with a powerful suite of visualization tools in a fully customizable environment.

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!

Sites with soil contamination often are also subject to contamination of the groundwater.  Groundwater contamination can be very complex and a thorough understanding of the geology of the aquifer and contaminant sources is critical in planning remediation efforts.  EnterVol offers C Tech’s proven technology within the ArcGIS environment.

There are many businesses that release emissions into the air due to their daily processes. Because there are regulations in place to minimize pollution, these businesses need the help of air testing companies to make sure they are in compliance with the regulations. We perform air emissions testing to let your business know whether it falls within the set guidelines, as well as emissions monitoring services to ensure you remain within the regulations. This will keep the environment around your plant healthy and ensure you don’t accrue fines for violations.

EVS, MVS, and EnterVol excel in their ability to handle analysis and visualization of geophysical data. For example, 3D resistivity can be analyzed from 2D ground arrays and airborne surveys. Electrical resistivity surveys offer the ability to inexpensively collect vast quantities of three-dimensional subsurface data. Environmental sciences, mining, archaeology and many other disciplines can benefit from these measurement techniques. However, their large irregular datasets offer significant challenges related to analysis and visualization. C Tech’s EVS , MVS, and EnterVol excel in their ability to address these complex issues.

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.

The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote lab results can take several days to a week. InfraCal TOG/TPH Analyzers allow for oil in water testing at the well site in less than 10 minutes. The sampling requires a few simple steps that can be performed by non-technical personnel. The water is mixed with the extraction solvent, shaken, and then presented to the analyze for measurement. The same InfraCal TOG/TPH Analyzer can be used for TPH in soil if a spill or pond leak occurs to determine the contaminated area. The analyzer features: -Results in under 15 minutes -Detect levels as low as 10 ppm -Portable, rugged, lightweight, easy-to-use -Battery operable -Ideal for field or lab use

C Tech is known worldwide for our innovative approaches to Soil contamination modeling. Soil contaminant data can often span 6 orders of magnitude or more. Extremely high gradients coupled with limited budgets make it very challenging to develop reasonable models of contaminant distributions. EnterVol incorporates C Tech’s proven expert systems to conquer the challenging process of developing reasonable volumetric plume models. EnterVol provides the ability to present reams of complex geologic and environmental contamination data in a form that is easily comprehended by a judge, jury or the public. In our world where 3D models are commonplace on television, environmental litigators cannot afford to present complex geochemistry data with graphs and charts. You need defensible, data driven models with the realism to win the jury’s minds and the statistical foundation and sound science to stand up to the most rigorous cross examination.

The migration of magma towards the surface in a volcano is usually accompanied by the release of gas that was previously dissolved in the magma itself. In an open conduit volcano, most of the gas escapes through the main conduits of the volcano and then through the craters. However, a significant proportion (approximately 10%) of the total quantity of gas can escape laterally through faults and fractures that are normally present in the flanks of a volcano. Therefore, increases in the amount of gas emitted usually indicate the initial stages of magmatic migration towards the surface.

The Series 8900 Naphthalene Analyzer provides direct measurement of Naphthalene in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits and at remediation and Superfund sites. The Series 8900 Naphthalene Analyzer employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Naphthalene and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Naphthalene is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Monitoring the dilution and movement of a tracer introduced into the water column provides an excellent means of determining the path that may be followed by a discharge and the rate at which dilution is likely to take place. Fluorescent dyes such as Rhodamine, Fluorescein or Agma are the most frequently used tracers for such investigations. Chelsea Technologies has been providing dye tracing systems for over 30 years. Typical applications include sub-sea pipeline leak detection, pollution studies, natural water flow analysis (rivers, lakes, ocean currents, cave water flows, groundwater filtration etc), sewer and storm water drainage analysis. The Chelsea systems can be configured for a wide variety of tracers, are highly sensitive, robust, and deliver real-time data. They can be moored, profiled, towed or affixed to ROV / AUV platforms.
