Detailed Summary

The most common hydrostratigraphic sequence in the Lakewood area starts with surficial sand and/or sand and gravel (up to ~30-40 feet), underlain by variably thick layers of clay, silt, or sandy clay (commonly 10-40 feet where present). Beneath this, a second thicker sand or sand and gravel aquifer is prevailed, with occasional finer beds (silt or clay), with the deepest interval sometimes reaching granite bedrock below ~80-240 feet. The majority of productive residential wells are screened in the lower sand/gravel interval from 35 to 82 feet. Wells terminating on granite are uncommon except at greater depths. Typical static water levels range from 20 to 70 feet below surface. This profile is averaged from a random sample of permitted private wells in the region, discarding unusual or extraneous records for generalized mapping.

Expected Geological Layers

Depth (Feet)Formation TypeDescriptionCharacteristics
0 – 30 ftSand or Sand & GravelFine to coarse surficial sand, often with gravel - glacial outwash or ice contact deposits; locally mixed with some silt. Highly permeable.
Hardness: Unconsolidated
30 – 50 ftSandy clay, silt, or clay (discontinuous)Tan or gray sandy clay, silt, or clay - can be absent in some wells but forms an aquitard where present.
Hardness: Plastic to compact
50 – 82 ftSand or Sand & GravelCoarse sand and/or gravel - highly transmissive main water-bearing unit. Occasional intervals described as water-bearing sand. This is the most common domestic aquifer.
Hardness: Unconsolidated
82 – 240 ftGranite Bedrock (where encountered)Fresh to weathered granite - forms aquiclude; wells rarely drilled into this unit except as needed for supply.
Hardness: Very hard crystalline
