Water Surface vs Groundwater

Ambience: drilling for water
Rorrer: We have our six-inch air hammer drilling through bedrock in hopes of finding adequate fractures that have plenty of clean groundwater.

When you're drilling a well, you want to make sure you're not getting surface water but ground water. What's the difference? Stay Tuned. I'm Jim Metzner and this is the Pulse of the Planet.

Rorrer: So right beneath our feet you're going to have some surface water that's probably influenced not only by the rainfall and snowfall, but the river as well.

Eric Rorrer is President of Rorrer Well Drilling Incorporated; he's been drilling wells for over 25 years.

What we want to differentiate between surface water and groundwater is to get our well casing all the way down into a good, competent bedrock. Once we do that, the water then has to flow through all of this formation the rocks, the dirt, and, basically, allow Mother Nature enough time to clean the water. Once it gets down through all of the fractures and all of the bedrock, then, as it flows into the well, it's went through that process and now is considered groundwater. So, if we try to get the water in a surface application, then it's going to be influenced heavily by rain, by snows, by anything at all on top of the ground close to the surface. It's not going to have time to filtrate through the ground.
We are very fortunate in this country and very blessed to have a lot of groundwater, but, like any natural resource, we have to be good stewards of that groundwater. We cannot pump it out endlessly for various uses and not have enough water to filtrate back through the ground to replenish that groundwater and those aquifers. So, responsible management, responsible use of the groundwater is, indeed, very important. It's not an endless supply.
