[pdf] Sonic drilling employs a high frequency, rotary vibratory drill that is designed to fluidize, overburden, and fracture rock faces. This process results in seamless casing advancement or continuous core samples that can be accessed without the application of drilling fluids.
[pdf] Some drillers dig blindly, which increases the risk of striking a weak aquifer. Seasonal Variations – Groundwater levels fluctuate, especially during droughts, reducing output in certain regions. Over-pumping – Drawing water too quickly can reduce pressure in the aquifer, lowering yield.
