About Us - Andrew and Teisha Vandekop - Well Water Finders

Hi! I’m Andrew Vandekop, the Well Water Finder! Using patented technology invented by my family, we help landowners determine where to drill a water well. It was my father Franz who came up with the initial design of a system that uses electromagnetic waves to find the depth of water under the ground. Thanks to his genius, Well Water Finders can survey your land and pinpoint exactly where water is located to assist a water well driller in hitting water the first time.

It all started about 20 years ago when when my dad initially came up with the design. Along with geophysical research from my mother Bridget, the three of us obtained a US patent (US 6188221) and traveled the country helping landowners find water, oil and gas, under their properties.

About five years ago, we developed enhanced capabilities to map the location and depth of aquifers and ground strata, and launched EM Locator Technology, LLC. In November of 2020, we were granted a second U.S. patent (US 10830915).

In 2021, my wife Teisha and I created Well Water Finders, LLC. We use the EM Locator technology to help people find water and oil and gas. We currently serve the great state of Texas, and are working to serve communities all over the world, helping them find water.
