Hydrogeophysical Imaging- Topliff Drill

HYDROGEOPHYSICAL IMAGING

OVERVIEW

Hydro was contacted by the Topliff Family Trust to image the aquifer beneath their property. A declining water table caused the well yields at three wells to fall to less than 200GPM each. The aquifer-imaging surveys were conducted in three areas of the property, and the most-promising area was selected from a comparison of all the new data to the existing wells. One small area was unique in that it showed good sand and gravel quality at a greater depth than the current wells.

MAIN CHALLENGE

When working around existing wells, it is sometimes difficult to get accurate data due to the electromagnetic effects of running pumps and electrical lines. One of the areas investigated was immediately surrounding an existing well to determine if drilling a nearby replacement was a better decision than drilling a new well in a new area.

HYDRO’S SOLUTION

Hydro was able to have the electricity turned off enabling successful imaging around the declining well. The image showed that the aquifer did not significantly improve in the areas 360 degrees around the well. The new area data looked superior to the data at the existing well, so Hydro Resources was able to focus the test hole drilling in the best area shown by our aquifer-imaging
system. Other test holes were drilled outside Hydro Resources’s recommendations and the findings in those areas were very poor for groundwater development.

ADVANTAGE

Six test holes were drilled on the property, and the recommended test hole encountered porous and permeable deeper aquifer material than was found at existing wells. Our recommended site was drilled and completed, consistently producing over 1600 GPM. According to the public records, this is the highest volume well ever drilled in the entire Township.
