Recommended Method
Based on a synthesis of the sampled well logs from the Comstock Park and immediate region, the representative geological profile is characterized by initial surficial sand or sandy-clayey material (0-5 ft), underlain by thick sections of clay with subordinate inclusions of stones or gravel (5-60 ft). These are typically followed by a series of sand, sand with gravel, or sandy/gravelly clay units (60-145 ft), with the principal water-bearing zone (moderate to high-yield) encountered from about 90 to 145 ft below grade. Occasional deeper clay and sand/gravel/clay units may occur, but most residential wells are completed within the upper 100-150 ft. Wells yielding 5-20+ GPM are frequently reported when completed in these sand or sand/gravel zones.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 5 ft | Sand/Sand & Clay | Fine surficial sand or sandy-clayey loam, occasional stones | Color: Light brown to gray Hardness: Loosely consolidated |
5 – 60 ft | Clay (with stones/gravel layers) | Hard to firm gray or brown clay, may contain stones/gravel layers or lenses, occasional silty intervals | Color: Gray to reddish-brown Hardness: Hard to compact |
60 – 90 ft | Sand/Silty Sand/Sand & Gravel | Medium to coarse sand, locally silty with gravel inclusions, water bearing | Color: Tan to gray Hardness: Loose to medium compact |
90 – 145 ft | Sand & Gravel / Coarse Sand | Coarse sand and gravel, principal aquifer zone, high permeability, frequent well screens here | Color: Variegated gray/yellow Hardness: Loose to moderate |
145 – 160 ft | Clay/Sandy Clay (local) | Clay, sandy clay, or clay with gravel, less frequent and may locally be absent | Color: Gray to brown Hardness: Compact |
