Crockett County, Tennessee
The most common soil here is Grenada, on about 26% of the land: a silt loam, smooth, like flour. Loring and Collins come next.
About 8% of the land drains well, and 21% stays wet for long stretches; groundwater comes within two feet of the surface under 64% of it.
USDA rates 96% of the land very limited for a standard septic drain field, and 95% very limited for homes with basements. That means extra cost or special design, not that it can't be done.
Worth knowing: 34% of the land floods occasionally or more.

Soil Orders in This Area
The USDA classifies every soil into one of 12 soil orders. Here are the dominant orders found in this survey area.
What This Means
Building & Foundations
About 95% of soils are rated "very limited" for dwellings with basements. Specific challenges include steep slopes, poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.
Septic Systems
About 96% of soils are rated "very limited" for septic absorption fields. Despite good drainage overall, limitations may stem from shallow bedrock, steep slopes, or seasonal conditions. Engineered or alternative systems are frequently required. Always get a professional perc test before purchasing land that needs septic.
Gardening & Agriculture
Drainage is generally favorable for gardening. Adding compost and mulch will improve fertility and water retention. Test your soil's pH before planting — most vegetables prefer 6.0-7.0.
