East Lansing Meridian Water & Sewer Auth
East Lansing, MI48823-7246
Typical East Lansing area wells penetrate glacial clays and gravels, underlain by bedrock composed mainly of shale and sandstone. Water is most often sourced from the upper bedrock aquifers at depths between 120 and 200 ft.

Recommended Method
A representative geological profile of East Lansing shows an upper sequence of brown/gray clay (with gravel in places), typically 15–30 ft thick, followed by additional silty to sandy clays with intermittent gravelly or sandy zones to about 60–75 ft. Beneath these fine-grained sediments, there is a consistent transition to bedrock, which is primarily shale interlayered with sandstone. In most wells, initial shale is encountered beneath 65–75 ft, sometimes with a thin sandstone/sandrock or sandy shale interval above or within the shale. Below this, most wells show alternating bands of shale and sandstone down to total depths of 150–425 ft. Yields are best from the upper sandstone or sandy shale zone. A typical residential well for 5–15+ GPM is completed between 140 and 200 ft, with static water levels commonly between 14 and 54 ft below ground.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 20 ft | Clay (Brown/Gray, Glacial) | Brown and/or gray clay. Locally includes gravel or sand, especially in basal part. | Color: Brown to Gray Hardness: Soft to Firm |
20 – 65 ft | Clay/Silty Clay (with Gravel & Sandy Lenses) | Gray or brown silty to sandy clay, frequent inclusions of fine gravel or sand especially towards base. Locally stoney. | Color: Gray, Brown Hardness: Firm |
65 – 90 ft | Sand or Sandstone Transition | Red, white, or gray sandstone, or compact sand beds, often marking base of glacial sequence or start of bedrock. Sometimes interbedded with shale. | Color: Red, White, or Gray Hardness: Medium |
90 – 230 ft | Shale Interbedded with Sandstone | Mostly gray or red shale, with occasional interbeds of sandstone or sandrock, sometimes with minor clay. Yields water to wells. | Color: Gray, Red Hardness: Soft to Hard (variable) |
230 – 320 ft | Thick Shale with Subordinate Sandstone | Dominantly shale, often soft to firm, with thin, hard beds or streaks of sandstone. Sometimes grades into harder sandstone below. | Color: Gray, Red, Black Hardness: Soft to Hard |
320 – 425 ft | Sandstone and Shale (Deeper Sequence) | Interbedded gray or brown sandstone and shale, more common in deepest wells. Sandstone is generally water bearing. | Color: Gray, Brown Hardness: Hard |
