Abstract
Total organic carbon (TOC) is of concern to water providers due to the propensity of natural organic matter to react with chemical disinfectants to form carcinogenic byproducts called trihalomethanes (THM's). The natural occurrence and physical/chemical removal of natural organic matter in the lime softening process were investigated. Various jar test methods were employed to investigate removal of TOC from surface waters throughout eastern South Dakota. Results from each jar test method were compared statistically to other jar test methods. Jar test results were also compared semi-quantitatively with pilot-scale and full-scale results in an attempt to produce a bench-scale method that would simulate pilot-scale and full-scale removal of TOC. The molecular weight distribution of dissolved natural organic matter from various South Dakota surface waters was analyzed and compared.
