Recommended Method
A representative geological sequence for Frederic, Wisconsin, based on well logs, consists of an upper sand or sand/gravel layer, underlain by alternating clay and coarser granular units (sand, gravel, silt). In a few deeper wells, a hardpan, silt, or occasionally a weathered bedrock is hit at greater depths. Most productive residential wells are completed in the main sand/gravel aquifers above any hardpan or silt encountered, with static water levels commonly between 6 and 59 feet and estimated well yields exceeding 5-15 GPM. Wells are mostly rotary-drilled, cased through the unconsolidated zone, and grouted from surface to casing tip.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 15 ft | Sand or Sand & Gravel | Fine to coarse grained sand, may be mixed with gravel; occasionally includes topsoil at very shallowest depth. | Color: Varies (often light brown to tan) Hardness: Loose to medium |
15 – 50 ft | Clay, Clay & Gravel or Clayed Sand & Gravel | Mostly clay or a clay/gravel mix; may have some coarse components. Acts as a confining or semi-confining layer. | Color: Gray to brown Hardness: Firm |
50 – 80 ft | Sand & Gravel (coarse to medium) | Primary water-bearing unit for many wells. Generally well sorted, may be described distinctly as coarse sand or sand & gravel. | Color: Yellow to tan to gray Hardness: Medium to medium-coarse |
80 – 110 ft | Sand, Coarse Sand & Gravel or Silt/Hardpan | Sand and gravel remains common but may transition to silt, hardpan, or highly compacted material (occasionally with some cementation). | Color: Gray, tan Hardness: Medium to hard |
110 – 145 ft | Silt, Hardpan, or Weathered Sandstone/Traprock | Less frequently reached by residential wells; where encountered, serves as a lower confining unit or transition into bedrock. May be described as hardpan, silt, or (rarely) traprock. | Color: Gray, brown Hardness: Hard |
