Our Hydro-geology Survey consists of investigating the local watershed and water cycle, including surface and subsurface water, in order to understand the sources of groundwater in porous/fractured rock environments.  This Survey results in identifying the optimum areas to install a water supply well on a specific parcel.

The subsurface investigation is supplemented with an electromagnetic tool (EM-tool) that identifies the best subsurface drilling target with a very high success rate for a specific parcel.  

Ground surface hydrology, sub-surface geology, and topographical landmarks are an essential part of understanding the value of different locations.  Our reconnaissance-level (recon-level) surveying service delivers information and advice to facilitate the success of a productive water supply well.

Collecting local data on existing water wells in the area, ground surface topography elevations, and using the EM-tool, provide correlations of hydro-geologic consistency which supports a better water well drilling target that minimizes the need for multiple installation of test wells.

If there is any water beneath your property, it would collect more readily in porous/fractured rocks identified by this recon-level Hydro-geology Survey in association with the EM-tool.

Our services provide a Preliminary and Interpretive Commentary of a recon-level Hydrogeology Survey that is specific to a particular land parcel.  The Survey is complemented with an EM-tool.  In addition, the Commentary includes a portion of a topographic map (showing the property location and any important hydro-geologic features to estimate planned well depths) and a Google Earth aerial photograph (showing the approximate locations of the traverses and the property boundaries).

  A brief discussion of the local geology based on internet accessible reports and maps (that are cited) is included in the Commentary.  

The Commentary includes:

1.    A brief evaluation of the local precipitation;

2.    Estimated average elevation of the parcel;

3.    Estimated average elevation of relevant and important hydr-ogeologic features;

4.    A summary of the depths of other wells reported to the CA Department of Water             Resources that were installed within a 0.5-square mile of the parcel;

5.   Traverses on the parcel are selected to avoid any cultural features or obstacles

            that may impact the EM survey; and

6.    Traverses are also chosen to allow easy access to the target location for a drilling rig thus minimizing costs to install access roads for the drilling equipment.

The Commentary includes a brief summary (and rationale) of the Hydro-geology which is used to estimate the approximate depth of the target for a water supply well.  In addition, a brief discussion is included on the general procedures of installing a water supply well and recommended onsite inspection during the installation of the well.  A discussion is included on the depth to drill the exploration well, especially in fractured rock environments.

A cross section is like cutting an apple vertical in half

and viewing the inner mechanical fabric.

  It's very simple, like an X-ray

- Black represents: Porous and or fractured formations. Water collecting zones.

- White represents: Harder compressed granitics, above illustration.

If there is any water beneath your property,

it would collect more readily within the black area.
The heart of the black area should be the approximate drilling target for your water well when coupled with the hydro-geological aspect.

Black arrow in the chart shows the area where a water witcher (dowser), would select for drilling.  Upper right hand corner.   Not in the optimum area.

Only computer technology can image the geometry of your subsurface like an X-ray.

*The Computer Scan shows you the drilling target, where to drill for the potential of water and the Computer Scan will show you where not to drill.

Computerized electronic instrumentation coupled with hydro-geological data generates more coherent subsurface Hydro-geological data.

With this information you eliminate misleading advice based on
inaccurate or inappropriate surface studies.

You then can make better informed drilling decisions, and you
will be able to pinpoint your drilling targets more precisely.
