Typically karst areas only, otherwise we drill to underground aquifers like porous bedrock past confining layers that hold water. Most are not underground caves but layers of porous substrate like sand and gravels, bedrock fractures
Do you have a pic of how you fastened your camera to the downhole rig? I’d like to do the same for my old well, but don’t want to risk losing my camera.
I think it'd be neat if somebody did a bore exploration video like this only to find small critters living in some water-filled void. It would be an opportunity for doing some science at that point. (If things could live off of deep ocean vents, then why not some other mineral consuming bacteria?)
and this is why my former landlord told me not to drink out of the tap it was well water, that shit stunk and gave me heartburn. i thought wells were clean
No normally, the PVC extends to stable rock. In my area casing typically is only the first 60-80ft of a 200-foot well. Below that, the bedrock will be fractured, allowing water to flow. This well appears to be drilled down into an aquifer that looks like it has been pumped dry. This is not what a well typically looks like inside. At least in my area. The purpose of casing and casing grout is to keep surface water out of the borehole in order to prevent chemicals and pathogens from the surface groundwater from entering the well. Casting is also used to keep soft layers from collapsing into the borehole, but casing is expensive so it typically stops at stable rock.
PVC casing? And it appears badly ruptured. Well casings in the NE are typically steel and about 50’ long. 100’ if you have a well driller who isn’t a gambler. And an aquifer that low would be a sign to move. Cool video tho.
I'm trying to figure out the insane pump you need to get the water up this high, or am I missing something here? (drilling wells isn't very common in The Netherlands, where I'm from, though they used to be more common in rurar areas back in the days)
