Recommended Method
Most Hayward-region wells show a sequence dominated by unconsolidated glacial/fluvial sand and gravel (sometimes mixed with silt or coarse gravels) from the surface, frequently with at least one clay-rich horizon at varying depth. Deeper wells (>90 ft) may penetrate multiple aquifer units including coarse gravels and minor rock fragments or silt, but the prevalent aquifer is in the sand/gravel zone. Water is typically encountered between 20 and 55 feet below the surface, with static levels in that range. The most common drilling method is Rotary-Mud Circulation. Casing generally extends through the upper 30–100 feet depending on final depth and construction method, and bentonite grout or drill slurry is used to seal the annulus in the upper intervals.
