About SepticSoil

SepticSoil answers one question for land buyers, builders and agents: is a septic system likely to work on this lot? We pull the public data a soil evaluator would look at first and explain it in plain English.

Data sources

• USDA NRCS Soil Survey (SSURGO) via Soil Data Access: "ENG - Septic Tank Absorption Fields" interpretation, water table, bedrock, drainage, hydrologic group.
• FEMA National Flood Hazard Layer: flood zone at the point.
• USGS Water Data OGC API: groundwater wells within one mile.
• U.S. Census Geocoder: address to coordinates.
