Typical Well Depth
Static Water Level
Recommended Method
The representative well profile for the Ashland region is characterized by initial silty or sandy topsoil, underlain by a thick sequence of red, sticky, or firm glacial clay (often extending over 80–100 feet). Interbedded within or underlying the clay, coarse sand, sand & gravel, or mixed sand/hardpan intervals are present and sometimes water-bearing. At greater depths, sand and gravel layers become thicker and more frequent; in some wells, sandstone or clayey sand is encountered below 100–200 feet. The average static water level is between 15–100 feet, depending on well depth and specific location. For a residential yield of 5–15+ GPM, wells are typically 120–200 feet deep; higher-capacity or sandstone wells may reach 200–270+ feet.
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 2 ft | Topsoil | Organic or mixed sandy/silty topsoil, dark color. | Color: Dark Hardness: Soft |
| 2 – 85 ft | Clay (glacial) | Primarily red or sticky/firm glacial clay; may be interbedded with minor silt, some sand inclusions possible. | Color: Red to Brown Hardness: Sticky to firm |
| 85 – 120 ft | Sand & Gravel (water-bearing) | Coarse sand to sand & gravel, occasional hardpan and cobble/boulder zones; lithified enough for modest water yields. | Color: Tan to Brown Hardness: Medium, sometimes hard |
| 120 – 175 ft | Sand (coarse, water-bearing) | Coarse sand, cleaner and more permeable, often main aquifer zone, may include minor gravel/hardpan bands. | Color: Tan to Yellow Hardness: Medium |
| 175 – 200 ft | Mixed Sandstone/Sandy Layers or Clayey Fine Sand | Transition to fine sand, sandy clay, or locally sandstone bedrock. Can be harder, lower yielding, but present in deep wells. | Color: Light to tan Hardness: Hard/Firm |
