Everything You Need to Know About Locating Well Water in California

As many Americans (especially Californians) know, there’s been a severe drought going on out west for quite some time now. In fact, the drought began almost six years ago and has been the driest period California has ever seen in the 163 years the state has been recording its weather. While the drought has affected about 98 perfect of the state, there is some hope. There is evidence that California is actually sitting on an enormous amount of groundwater. It’s estimated that there are 2.7 billion tons of freshwater sitting below the surface!

The only problem is that we don’t know exactly where all of that groundwater is located. Drilling all over the place in hopes of striking it rich is a waste of time and money. Locating well water in California is an intricate and time-consuming process, but it’s well worth it in the end.

How do we detect groundwater?

The first step in locating groundwater is finding a plot of land. Our customers will contact us if they feel like they need the benefits of having fresh water at their disposal 24/7. After we’ve arrived on site, our professionals drill four steel rods into the ground, and run cables from the rods to an advanced Seismo-Electric Survey Instrument system. Next, we’ll set off a black powder charge into the ground, which creates a pressure wave. If the pressure wave moves over a source of groundwater, a disturbance will be detected by the Seismo-Electric Survey Instrument system. That disturbance will let us know that there’s water, and also how far down we’ll have to drill to get to it.

We run this test five times to ensure our customers are getting accurate information. Once the tests are complete, our experienced geophysicist looks over the data to validate our field findings. After the results are back, and we’ve confirmed you have groundwater, you’re free to drill away and enjoy all of the benefits that come with owning your own well.

We can perform the groundwater test on any number of different properties. We do testing on residential, commercial and agricultural sites. We also test land that’s undeveloped or is about to be developed. Since fresh water is somewhat scarce in California, finding groundwater on a site can greatly increase the property’s value.

Is the process worth it?

While it certainly is time-consuming and difficult, locating well water in California is worth every second spent searching. If you want proof, you could talk to some of our recent clients. We recently found a drill site for a client that is producing over 800 gallons of water per minute (GPM)! The client was only hoping to get about 80 GPM from the well, so getting 10 times more water than they were expecting was quite a pleasant surprise.

Contact National Groundwater Surveyor Inc. when you’re ready to start the process of locating well water in California. We look forward to assisting you and helping you access groundwater for your residential, commercial or agricultural property!
