Mapping Contaminated Groundwater

If you are a business owner, farmer, or government official charged with municipal planning, you may find it crucial to understand the location of extent of a contaminated groundwater resource. We canhelp you locate the groundwater resource precisely, and discover to what extent the resource exists in the subsurface. When you are able to pinpoint contaminated groundwater, you can select culinary or irrigation well locations with confidence. With AquaTrack you can:

• Map and tract contaminated groundwater
• Identify areas of salt water intrusion
• Accurately map groundwater resources
• Continually monitor groundwater resources
• Optimize culinary or irrigation well placements

AquaTrack is a patented, magnetic-based groundwater mapping solution that has proven extremely accurate and cost effective in mapping groundwater resources.

Why Choose Us?

When you choose Willowstick, you will receive detailed maps that delineate areas of high and low water concentrations as well as the preferential flow paths of the water within the subsurface. Armed with this information you can effectively monitor changes in the groundwater, optimize production well locations, and enhance exploration of new resources.

The information generated by this revolutionary technology helps you understand the current utilization of your groundwater resources or the impact that pollution may have upon the overall supply. As a business owner or government representative, you will be equipped to respond to problems, maximize productivity, and minimize environmental impact.

And this information will greatly enhance the placement of culinary or irrigation production wells. Because you will be able to “see” the character of the resource, you will be able to ensure that production wells are strategically placed so that well-construction costs are mitigated and that the well can supply sufficient water for future needs.

Smart Exploration

Because we provide you with a map of the exact location of water, your exploratory efforts become much less complicated and much more reliable. Most geophysical technologies energize the ground and then, through their interpretative processes, estimate the location and extent of groundwater. AquaTrack directly energizes the groundwater of interest and the result is a much more conclusive understanding of where groundwater is and where it is not.

We can usually conduct your Willowstick survey in a matter of days instead of weeks and months, as is often the case with other geophysical methods. In addition, the AquaTrack survey is non-intrusive and does not require bulky equipment or the detonation of explosives. In fact, in most cases, a survey can be conducted using existing wells. Because of these advantages, you will realize significant value per dollar spent over traditional groundwater mapping techniques.

How it Works

AquaTrack uses a low voltage, low amperage, audio frequency electrical current to energize the groundwater. Electrodes are placed strategically in wells or other water bearing media near the survey area. Because the groundwater is a conductor, the electrical current follows through the groundwater between the electrodes.

The AquaTrack receiver measures the specific magnetic field generated by the electrical current, filters out interference, and amplifies the signal. Repeated measurements are recorded over time to ensure consistent results. The recorded data is corrected to remove fluctuations due to natural phenomena and man-made interference. The horizontal and vertical magnetic field magnitudes and directions can be measured to further define the extent and paths of groundwater.

The AquaTrack survey data are normalized to show relative highs and lows in the field data. These are referred to as anomalies that represent areas of different physical conditions. The changes in conductivity represent an increase or decrease in the presence of groundwater. In the simplest terms, the AquaTrack technology identifies where groundwater is most present in your area of investigation.
