Auburndale region wells typically penetrate thick clay and till, with minor sand, overlying a transition zone (sand/sandstone or decomposed rock) that gives way to competent granite or, less commonly, sandstone at depth.

Recommended Method
Based on a synthesis of multiple well logs from the Auburndale area, the representative geological profile begins with a substantial upper clay (sometimes clay-with-stones or till) unit, often extending from the surface down to approximately 30–60 ft. Below this, there is typically a transition layer that may include sand, sand and clay, sandstone, or highly weathered granite (when present). The dominant bedrock is granite, encountered at depths ranging from about 50–65 ft and extending to the full depth of most wells (commonly 100–240 ft), with occasional wells reporting sandstone instead of granite. The most productive residential wells for 5–15+ GPM generally penetrate into the granite bedrock and are typically completed between 100 and 160 ft. High capacity municipal or irrigation wells may use the full granite thickness to 200–240 ft as observed in several logs.
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 40 ft | Clay/Till (occasional stones) | Dense, often brown or tan clay, sometimes includes stones or gravel. May locally include small amounts of silt or sand. | Color: Brown/Tan Hardness: Soft to firm |
| 40 – 60 ft | Transition (Sand, Sand+Clay, Decomposed Granite, or Sandstone) | Sand, mixed sand and clay, or decomposed/weathered bedrock. In some areas, this horizon may be absent or represented as layered sandstone within clay. | Color: Tan, Brown, Yellow, or Mixed Hardness: Loose to medium |
| 60 – 220 ft | Granite Bedrock (occasionally Sandstone lower; see local variability) | Competent crystalline granite, occasionally overlain or interbedded with sandstone in some locations. This is the primary water-producing formation in the area. | Color: Pink, Black, Gray Hardness: Very hard |
