The typical geological profile in the Edgerton region consists of a thick sequence of sand and gravel extending from the surface, generally underlain by clay or silty gravel layers, and in deeper areas, glacial deposits transition into limestone and then sandstone bedrock. Most private residential wells are screened in the sand and gravel (surficial aquifer) or the upper sandstone, with a typical residential well depth around 80-100 feet and high capacity wells extending into the sandstone and limestone below 120 feet.

Recommended Method
Geological data from a representative sample of Edgerton and surrounding area wells indicates the most common layer sequence starts with sand and gravel from the surface (extending typically 40-80+ ft), occasionally interrupted or underlain by clay or clayey gravel. In high-capacity or older wells, the sequence continues to limestone (avg. 130-160 ft) and sandstone (below ~130 ft, anchoring wells to about 180-210 ft in the deepest cases). The median static water level ranges from 10-30 ft below grade. Most domestic wells target the sand/gravel aquifer or the top of the sandstone for sustainable high yields (15-35 GPM commonly reported). Standard casing extends to the bottom of the unconsolidated drift or just into the bedrock, with grout (cement or bentonite) typically placed to at least casing depth.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 60 ft | Sand & Gravel | Coarse to medium sand and gravel, occasional stones, tan/brown color, may be interbedded with minor clay or silt lenses. | Color: Tan/Brown Hardness: Loose to medium |
60 – 75 ft | Clay/Clayey Gravel/Silty Gravel | Gray or brown clay, occasionally with gravel or silty material, acts as an aquitard in some locations. | Color: Gray/Brown Hardness: Hard to sticky |
75 – 91 ft | Gravel/Sand & Stones | Clean gravel and sand, possible large stones, transition to coarser material near base of unconsolidated section. | Color: Mixed/Grey Hardness: Medium to hard |
91 – 130 ft | Clay or Silt (locally present, may be thin or absent) | Dense gray or brown clay; sometimes silty, sometimes absent; where present can vary 5-15 ft thick. | Color: Gray/Brown Hardness: Hard |
130 – 160 ft | Limestone/Dolomite | Hard, gray limestone or dolomite bedrock; upper few feet may be fractured or shaly. | Color: Gray Hardness: Hard |
160 – 210 ft | Sandstone | Soft to firm, water-bearing sandstone; color from buff to reddish, high porosity; continues beyond 180 ft in deeper wells. | Color: Buff/Reddish Hardness: Soft to medium |
