Septic services in Adams Run, South Carolina

Operators based within 12 miles of Adams Run

Listed by where the business is, not by who it says it serves. Every operator here was on the SCDES Onsite Wastewater Contractors list on the date its record shows, and the address it is placed by comes from that same list, so this is a checkable claim rather than a service-area promise. A South Carolina licence is issued by the state, not by a county, so operators further out can work here too; these are simply the ones closest to you.

Soil and septic suitability around Adams Run

The USDA has already rated this ground for exactly one use: a septic tank absorption field. Within 4 miles of Adams Run — 31,989 acres across 35 soil map units — it rates 99% of the land very limited for that use and 0% somewhat limited, and almost none with no limitation at all.

What the limitation actually is

A rating on its own tells you nothing you can act on. The reasons do, and around Adams Run the leading one is depth to saturated zone on 99% of the mapped area, followed by seepage, bottom layer on 83%. In full:

Limiting featureShare of areaWhat it means on site
Depth to saturated zone99%A seasonal water table sits too close to the surface
Seepage, bottom layer83%The layer beneath the trench is porous enough that effluent could reach groundwater without being filtered
Ponding29.6%Water stands on the surface
Filtering capacity27.2%The soil drains so fast it would not filter the effluent
Slow water movement12.3%Water moves through the soil too slowly for a drain field to keep up

Shares overlap: most soils here are limited for more than one reason at once, so these do not sum to 99%.

The soils themselves

The named soils and land types that make up most of the ground around Adams Run. Wadmalaw alone accounts for 17% of it.

“None in profile” means SSURGO records no bedrock or other restrictive layer within the depth it describes, not that none exists.

Area of interest: a 4-mile radius around the USGS Geographic Names centre point for Adams Run (GNIS 2812939, 32.7219, -80.3466), chosen because five of this state's communities are unincorporated and have no boundary to use, and because the lots that need a septic permit are in the ring around a town rather than inside it. Soil from USDA-NRCS Soil Data Access, SSURGO interpretation “ENG - Septic Tank Absorption Fields”, area-weighted by mapped acreage and by each component's share of its map unit.

This is a survey, not an evaluation of your lot. The permit decision rests on the site evaluation SCDES carries out for the specific parcel.
