Great question about well depth for drinking water! The answer really depends on a few factors, like the geology of the area and the water table.
But speaking of drilling, have you heard of the Traveling Block? It's a key component in the drilling process and helps to control the movement of the drill string.
When it comes to drilling for drinking water, it's important to have the right equipment and expertise to ensure the well is properly constructed and safe for use. One thing to keep in mind is that drilling deeper doesn't necessarily mean better water quality. In fact, drilling too deep can sometimes lead to contamination from natural sources like arsenic or fluoride.
