In an area of faulted, cavernous, carbonate rocks of Ordovician age near Lebanon, Missouri, sewage‐treatment‐plant effluent was traced from Dry Auglaize Creek, a losing Ozark stream, to Sweet Blue and Hahatonka Springs in an adjacent basin. Rhodamine WT dye (20‐percent solution) was used to trace the subsurface movement of the effluent. Activated charcoal packets and grab samples of water were collected at 10 sites where dye might be expected to reappear and at a control site outside the area. The leading edge of the dye reached Sweet Blue Spring, a distance of 22.5 km from the injection point, 25 to 30 days after injection, and Hahatonka Spring, at a distance of 29.0 km, 45 to 50 days after injection. The apparent underground travel rate, based on straight‐line distances between injection and resurgence points, was 0.6 to 0.8 km per day.
