About soil and septic evaluations in Missouri
Missouri's construction rule (19 CSR 20-3.060) names two site evaluation methods -- a percolation test and a soil morphology evaluation -- and gives the administrative authority with permitting jurisdiction the power to decide which one your site needs. DHSS runs two matching registrations: a Registered Percolation Tester (DHSS-approved training course plus written and practical exams, or existing OSE/PE/geologist qualification) and a Registered On-Site Soil Evaluator, most commonly qualified as a soil scientist (15+ semester credit hours of soils coursework, 3+ specifically in soil morphology, then a written and field exam scored 70% or higher). Both registrations run on a 36-month renewal cycle with continuing education. Conducting either evaluation for OWTS design or installation without the required registration, or misrepresenting yourself as registered, is a class A misdemeanor under RSMo 701.053.
One verified Missouri operator (Show Me Soils, serving the area west of St. Louis including Franklin County) advertises $350 to $550 for the evaluation depending on location -- one operator's current price, not a market average; get quotes from two or three registered evaluators serving your county. The permit fee is separate and varies by jurisdiction: three counties checked directly charge $90 (Moniteau), $150 plus a separate $60 building permit (Monroe), and $510 (Boone) for new construction. There is no statewide flat fee.
