Recommended Method
Analyzed well logs around Amery consistently show an unconsolidated glacial sequence overlying deeper consolidated layers. From the surface, wells usually encounter a thin organic topsoil (0-2 ft), followed by variable sand and sand/gravel layers (up to 60-80 ft). This is frequently underlain by interbedded clay or clay with gravel (to ~90 ft), then more gravel, sand, or broken limerock (frequently to 125-180 ft). In some wells, the deepest layers are sandy, sandrock, or sandstone, encountered below 125-150 ft. For residential wells requiring 5-15+ GPM, screens are commonly set in thick, clean sand/gravel or coarse sand layers, often between 60 and 120 ft, sometimes deeper with casing seated just into consolidated or hard layers. High capacity wells typically need to reach the deeper sand/sandstone units or largest gravel layers.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 2 ft | Topsoil/Organic | Loose surface soil, organic-rich. | Color: Dark brown/tan Hardness: Soft |
2 – 15 ft | Sand | Fine to medium sand, unconsolidated, some variations in color (tan/yellow/brown). | Color: Tan/yellow Hardness: Loose |
15 – 60 ft | Sand & Gravel | Well-sorted sand and gravel, primary residential aquifer. Coarse zones commonly targeted for screen/set. | Color: Tan/gray/yellow Hardness: Medium-Loose |
60 – 90 ft | Clay (with minor gravel lenses) | Dense glacial clay, occasional sand/gravel or broken up gravelly clay zones. | Color: Brown/gray Hardness: Hard |
90 – 125 ft | Gravel, Clay, Limerock (broken up) | Alternating layers of gravel, clay, occasional limerock and hardpan, transitional to deeper aquifer units. | Color: Gray/brown Hardness: Medium to Hard |
125 – 170 ft | Sandrock/Sandstone | Medium to fine sandrock or sandstone, principal deeper aquifer where present. | Color: Yellow/gray Hardness: Medium |
170 – 180 ft | Medium Sand/Occasional Hardpan | Transition to medium sand, sometimes encountered as 'hardpan' at depth. | Color: Gray/brown Hardness: Medium |
