Tools of the Trade: Online Geologic Maps
Geology is vitally important in selecting a location for a new well, determining how deep the well needs to be, estimating potential yields and identifying potential water quality problems. While…
Tools of the Trade: Google Earth
When we are siting locations for new wells, we have a variety of tools we use to increase our chances to drill a productive well. One of my favorite tools…
Water Exploration in Karst
They say that the only thing certain about karst is its uncertainty, and that definitely holds true in Middle and East Tennessee. Even though karst geology does present some challenges…
Wellhead Protection and Source Water Assessment
When locating a new well, finding the water is only part of the challenge. Making sure that water that the well produces is clean – and is likely to stay…
Vertical Profiling of Wells
Vertical profiling of wells for both flow and water quality characteristics can be an extremely useful technique when it comes to dealing with ongoing well issues, or in final design…
Well Video Logging: A Key Diagnostic Tool
It is hard to overestimate the value of video logging when it comes to diagnosing problems with a water supply well. While various diagnostic tools and chemical tests are available,…
Well Entrance Velocity – An Often Overlooked Well Performance Factor
On the face of it, it would seem that bringing as much water as possible into a well as fast as possible would be a good thing, however that does…
Using Specific Capacity to Monitor Well Performance
Because it usually requires very little effort to collect the data necessary for the calculation of Specific Capacity, it is an extremely useful measurement that can be used to identify…
Well Health – The 3 Major Categories of Well Performance Problems
All wells will experience performance declines over their lifespans, some wells more rapidly than others. For instance, wells in alluvial deposits, while generally more productive than bedrock wells, tend to…
The Importance of Proper Well Development
We see many wells, including new ones, that are not performing as they should, with specific capacity and well efficiency much lower than they should be for the hydrogeological conditions.…
