About soil and septic evaluations in Delaware

Delaware requires a DNREC-licensed Class D Soil Scientist/Site Evaluator for a full site evaluation. Class D authorizes individual soil evaluations, soil investigation reports, feasibility studies, and percolation, permeability, or hydraulic-conductivity tests; D.1 covers ordinary new and replacement work, with D.2 and D.3 adding broader studies. Class A is a narrower percolation-testing credential and does not authorize the full evaluation. Class D applicants follow specified education and supervised experience paths, pass DNREC's written exam, and satisfy a certification or field-practicum path. Licenses expire each December 31 and require 10 hours of continuing education. Use DNREC's Class D dataset to find candidates, then confirm current status because the sources do not establish its refresh schedule.

DNREC posts a $250 one-time site-evaluation review fee. This is the public review charge submitted with the Class D scientist's report, not the scientist's private fee. Other posted charges include $250 for a septic repair or component replacement, $250 for holding-tank construction, $250 annually for a holding-tank inspection, and $100 annually for a system compliance inspection when applicable. No current Delaware provider price was available from the reviewed sources, so there is no sound market range to quote. Ask several Class D evaluators for itemized quotes, confirm whether excavation or equipment is included, and keep the private fee separate from DNREC's review charge.
