The depth of a water well can have many determining factors. Location of the well is one factor that can affect depth, cleanliness of the water, and cost. Choosing a location is important, most experienced water well companies have historical records that have been recorded throughout the country. These records can be referenced to give you a good estimation of the geological formations in your region. Historical archives can also give homeowners a good estimation of the drought depths (lows and highs) of the water table. From the first recorded depth until today.
How deep can you drill a well, could be a loaded question. Groundwater is located at some depth everywhere on earth. Just because you can find water doesn’t mean it is safe to drink. Knowing the geography of your region is the best advantage that we have today. If you want clean water, it has to be filtered. That does not necessarily mean that you have to go out and buy a filter. The best man-made filters you can buy are modeled off of natural occurrences. That is why well drillers sometimes drill down past freshwater to reach a purer source. The earth is one of the best filters, just next to evaporation, and boiling. The advantage the earth has over a store-bought filter is depth / scale. For the water to get deep underground, it has to flow through many natural filters, dirt, sand, rock, and carbon. All the best particulate filters are layered and located right under our feet. This is why the aquifer data is so important.
In areas of drought, it’s always a good idea to take into consideration the amount of time it takes an aquifer to fill up. If the ground is dry and water is able to penetrate the substrate without any resistance .The particulates are not able to bond as well if the water table stays a consistent depth in an aquifer, The water retrieved will be more consistent. It is not possible for any company to know the exact depth a well will end up being, before it is started. A good estimation can be accurate, but before water is reached it is still just an estimation. It is our best practice to take into account all variables and communicate openly with the landowner before the ground is broken.
