Frequently asked questions

Q: How does your Seismo-electric system work?

The GF6 and a seismic source are used together to generate and collect the seismo-electric signal. The seismic source is used to create a sound wave (pulse). When the sound wave moves through aquifers the water in the aquifer moves relative to the rock formation. Ions in the water are dragged away from their partners bound to the rock and the electrical disturbance created travels to the surface at the speed of light and is detected by the antenna array. Each signal is separated in time from its neighbors by the propagation time of the down going seismic pulse. This gives unambiguous depth and thickness data, as with reflection seismic. The form of each signal gives information about the depth and thickness of the aquifer and this is used to estimate the likely yield from a water well drilled at the survey site.

Q: What are the site requirements for Dig Well Drilling to complete a well water survey on my property?

  • We need to have safe access to each sounding site with our 4X4 vehicle (otherwise in acceptable weather we can do remote soundings which require an additional investment).
  • The area to be tested generally needs to be a minimum of 50 feet away from any type of electrical power source (primarily underground power, underground pipe lines, and some buildings).
  • We need to have enough unobstructed native surface material (topsoil/sediments) to drive (install) four 3 foot 3 inch long 3/4 inch diameter electrodes into the ground. The electrodes are placed in a straight line and require an area that is approximately 16 feet long and 1 foot wide to complete each sounding. (The definition of unobstructed surface sediments is surface sediments that contain approximately 30% or less large gravel or cobbles. If the surface sediments contain more than 30% large gravel or cobbles then more soundings may be required to collect a sufficient amount of definitive information.)

Q: Where should I have the survey completed on my property?

In most cases, the property owner tells us the general area that they would like to have their water well, which is where we complete the survey. If you are unsure of approximately where you would like your well drilled or there are a number of dry or poor performing wells in the area then you have a few options to narrow the search for the right place to complete the survey. One option is to have Dig Well Drilling complete an extended sounding profile survey (soundings completed in a line but separated by approximately 250 feet) completely across your property which may help us located some good areas to focus on with a more detailed close sounding survey. Another option is to have a study of the existing wells in the area, which may help find a pattern common to the good wells.

Q: How many soundings will I need on my property?

Every property varies and some properties need many more soundings than others but as a general rule we recommend a minimum of 5 or more soundings for residential clients and 10 or more soundings for agricultural or land development and sometimes in residential areas where obtaining water is known to be difficult. We also recommend that the soundings be completed in a profile (line) or an organized pattern of some kind. The number of soundings needed to locate a usable water source will vary by area.

Q: Can you tell me anything while at my property?

The data collected on a subject property requires numerous hours of processing and research to ensure that the most accurate estimations are made by our field surveyors. The signal that is collected in the field does have some obvious signs that can indicate groundwater but, depth and yield estimations can only be made after the data is properly processed. We avoid any type of field interpretation to prevent mistakes.

Q: How long does it take to get the final results?

Mainly due to work load, it takes about three weeks to provide the final report to each client. For a small additional investment, we do provide a report expedite option which will make the final report available in as little as 7 business days.

Q: Are there any other geophysical methods used to help locate water?

There are quite a number of geophysical methods that have been used in an effort to help locate water. Unfortunately, the method we use is currently one of only two methods that obtains its signal directly from groundwater. Our system provides unambiguous depth and thickness details about the aquifer. Additionally, it is the only method that can provide you with approximate yield estimates that are directly derived from the signal we record from the movement of groundwater. Most of the methods that have been used in the past have significant limitations, including; poor depth resolution, inability to provide reasonably accurate yield estimates, and high cost just to name a few.

Q: How will my water well driller find well water?

Until now there were no accurate or affordable options to locate water wells. The two most common options are either picking a spot or well witching. Most well drillers will not suggest where to drill a water well because of the potential liability involved. Dig Well Drilling can survey your property and provide a printed report containing approximate water depth and yield.

Q: Will I have to drill more than one well to find water?

Although having to drill more than one well to find usable water does not happen every time, it does happen and when it does, it often more than doubles the original estimated cost of the well. We can help prevent the need for drilling more than one well by giving you a report that will help you find well water the first time.

Q: Should I hire a dowser to tell me where to drill?

Water well witching or dowsing has been around for a long time and often appears that it may work. It is important to remember that there is no scientific evidence to prove that water well witching works any better than just picking a spot to drill a well. Dig Well Drilling can successfully locate a good water well site and show the estimated depth to water and expected yield with reasonable accuracy by using seismo-electric technology.


*Our RISK-FREE GUARANTEE is for our combined services of water location (surveyin) and well drilling. After Dig Well Drilling has completed a survey and has recommended a site to drill (and drilling is done within 90 days of the survey) we will guarantee water to be present or the cost of drilling is free! We guarantee water to be present when surveying is done within 90 days prior to drilling. We cannot guarantee quality of water. Dig Well Drilling cannot recommend drilling in an area with an interpreted yield of less than 6gpm due to factors in the drilling process that can at times significantly, and detrimentally affect the final yield of a low yield aquifer. Non-recommended yields have the possibility of being as low as 0.0gpm. Since the aquifer conditions may be changing with time, it is possible that these changes could adversely affect its yield. It is because of this possibility that Dig Well Drilling suggests that if the client chooses to drill a well at any of the locations that Dig Well Drilling surveyed; the well should be drilled within 90 days of the survey completion date. If the client is using the combined services of water locating and drilling from Dig Well Drilling and the client chooses to drill at a site that has an interpreted yield of less than 6gpm, Dig Well Drilling cannot guarantee water to be present and cannot guarantee the cost of drilling. Dig Well Drilling does not provide drilling services outside of the 150mile radius from our business location in Nyssa, Oregon (except in certain cases, please contact us if you are close to the 150mile range and want our RISK-FREE GUARANTEE).
