Examination of well logs from Three Rivers reveals the most common subsurface sequence is: a thin layer of topsoil or clay (0-5 ft), followed by various combinations of sand and gravel sometimes interbedded with clay layers. The sandy/gravelly zones typically become thicker and coarser below 15-20 ft and frequently serve as the main aquifer at 35-70 ft depth. Clays, when present, are commonly brown/gray and range up to ~30 ft thick but rarely extend below 60 ft. Most wells reach final depths between 43 and 90 ft, nearly always terminating in sand or sand/gravel. Typical residential wells draw from depths of 45-70 ft to achieve reliable yields of 10+ GPM.
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 5 ft | Topsoil or Clay | Black clay, topsoil, or red/brown clay—overburden layer. | Color: Black/red/brown Hardness: Soft |
| 5 – 15 ft | Sand (Fine to Medium) | Fine to medium sand, sometimes with minor gravel; occasionally red or yellow in color. | Color: Light brown/yellow/red Hardness: Medium |
| 15 – 35 ft | Clay/Sand & Gravel (variable) | Brown or gray clay interbedded with sand and gravel; thickness and grain size variable. | Color: Gray/brown Hardness: Medium |
| 35 – 55 ft | Sand & Gravel | Main aquifer zone; sand and gravel, often fine to medium, some coarse intervals; good water-bearing characteristics. | Color: Light brown/gray Hardness: Medium to loose |
| 55 – 70 ft | Sand/Gravel/Clay (transitional) | Alternating sand, gravel, and thin clay beds; color light brown to gray; transitions gradually to cleaner sand/gravel with depth. | Color: Gray/light brown Hardness: Medium to loose |
| 70 – 90 ft | Sand or Gravel (coarse, lower aquifer) | Coarse sand to gravel; typically the deepest and most productive aquifer encountered in sampled wells. | Color: Light gray/yellow Hardness: Loose |
