Recommended Method
Across the West Branch region, the typical well profile shows an upper interval of varying sand and gravel (often mixed with clay), usually followed by one or more clay confining units, and then lower sand/gravel aquifers. The most consistent and productive water-bearing zones are coarse sand and gravel in the lower half of typical wells. Most domestic wells range from 40-70 ft deep, with high yields at 10-15 GPM. Shallower sand and gravel zones are present but sometimes separated from the lower water-bearing unit by clay. Regional total thickness to refusal/bedrock not observed in sampled logs, but typical geologic section extends to 90-100 ft. Residential construction typically screens the main sand and gravel aquifer between 30 and 70 ft below grade.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 6 ft | Sand, occasionally mixed with gravel | Fine to medium sand, locally some gravel. Represents surficial outwash or glacial sands. | Color: Tan to brown Hardness: Soft |
6 – 15 ft | Clay or Sandy Clay | Massive, locally silty or gravelly clay; poorly permeable. | Color: Red, gray, or tan Hardness: Firm to hard |
15 – 36 ft | Sand and Gravel (Aquifer) | Coarse sand and gravel, dominant water-bearing unit. May include minor clay partings. | Color: Tan to brown Hardness: Medium to coarse |
36 – 52 ft | Clay/Hardpan | Tight clay, occasional silt or very fine sand. Relatively confining; locally several feet thick. | Color: Gray, red, or tan Hardness: Hard |
52 – 68 ft | Sand or Gravel (Lower Aquifer) or Sand with some clay | Clean sand or sand and gravel, main productive zone for deep residential/high capacity wells. | Color: Tan, gray Hardness: Medium |
68 – 99 ft | Sand with some Clay or Gravel | Coarser sand, sometimes with clay lenses. Water-bearing in thick, continuous zones. | Color: Brown, gray Hardness: Coarse |
