About soil and septic evaluations in Georgia
Georgia's on-site sewage rules (Chapter 511-3-1) still define 'Percolation Test' and 'Percolation Rate' as rule terms, but the standard documented submission for a septic permit is a Level III Soil Survey, a soil-morphology evaluation rather than a timed drainage test. The person who prepares it holds a DPH Certified Soil Classifier credential: a $100 application fee, a written exam, current liability insurance on file with the State Environmental Health Office, and renewal every two years with 30 hours of continuing education (standard renewal $400, late renewal $500). Confirm any classifier's current certification against DPH's certification page and roster before hiring -- do not take a company's word for its own credentials.
The Level III Soil Survey itself is private-market priced: two Georgia-specific secondary sources report roughly $400 to $600 for a standard residential survey (with one source's upper estimate at $800), plus a possible Level 4 follow-up study at an additional $200 to $400 reported by only one source and not independently corroborated. The county permit fee is separate and set locally; the one district verified directly, Cobb & Douglas Public Health District, charges $110 for site review plus $250 for inspection/permit, $360 combined. Combining the reported survey range with that district's fee produces roughly $760 to $1,160 before installation; your own county's fee and site's survey quote will move that number.
