Recommended Method
Based on a synthesis of the submitted well logs, the representative geological profile for the Richland, MI area generally consists of upper layers of brown clay mixed with gravel or cobbles, interbedded fine or silty sands, and deeper substantial zones of gravel and sand & gravel. Some wells report intervals of blue/gray clay or fine sand and occasional presence of sandstone (outlier), but the most consistent pattern is an upper clay or clay/gravel cap transitioning downward to alternating sand/gravel and clay intervals. The principal water-bearing units used for supply are most often deeper sand & gravel lenses or beds below ~70-100 feet, with residential wells typically completed in sand & gravel at 80-110 ft. Static water levels vary from 15 to 60 ft below grade. Shallow productive zones exist, but higher and more reliable yields come from greater depths.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 25 ft | Clay & Gravel (sometimes with Cobbles) | Compact brown or gray clay, often mixed with gravel and occasional cobbles as a glacial deposit. | Color: Brown to Gray Hardness: Stiff |
25 – 50 ft | Clay, Sand & Gravel (transition zone) | Brown to gray clay with interbeds or pockets of sand, fine gravel, occasional silty or fine sand layers. | Color: Brown/Gray Hardness: Firm to Medium |
50 – 70 ft | Sand & Gravel (partially water bearing) | Mostly sand and coarse gravel, occasional minor clay bands, some cobbles possible; limited water yield. | Color: Tan/Gray Hardness: Loose to Medium |
70 – 93 ft | Clay (occasionally silty or with sand) | Gray or brown clay, sometimes silty or mixed with fine sand; typically less permeable and acts as aquitard. | Color: Gray/Brown Hardness: Stiff |
93 – 110 ft | Gravel & Sand (main water-bearing zone) | Coarse gravel and sand, high porosity and permeability, primary aquifer for most wells; excellent water production. | Color: Gray/Tan Hardness: Loose |
110 – 154 ft | Sand & Gravel or interbedded finer sediments (variable presence) | Deeper glacial outwash deposits, composition varies—may be mainly sand and gravel with occasional silt/clay interbeds. Not present in all logs, but encountered in some deeper wells. | Color: Tan/Gray Hardness: Loose to Medium |
