Data was collected by the SDDENR and by a survey sent out and collected by Paul Saffert and Dr. Delvin DeBoer from the water treatment utilities utilizing surface water sources. Enhanced coagulation jar tests, as defined by the D/DBP Rule, were performed on a representative sample of the surface waters of South Dakota. TOC removals were established from the 3x3 matrix of the D/DBP Rule and from the Stage 2 Enhanced Coagulation Jar Test Protocol. Simulated Distribution System tests were set up to establish a link between TOC removal and THM formation. Generally speaking, the source waters in the State of South Dakota are amenable to enhanced coagulation. Ferric chloride generally removed higher levels of TOC at lower doses than alum during coagulation. THM concentration was dependent on several factors including TOC concentration, pH, chlorination time and temperature.
