AbstractThe reduction of viruses and other pathogenic microorganisms has been demonstrated by Soil Aquifer Treatment (SAT) (Wilson et al., 1995). The capability of the process to remove Cryptosporidium parvum oocyst has not been documented. This project attempted to assess the effectiveness of the SAT process in the removal of C. pcirviun oocyst in secondary effluent. Water samples were collected from monitoring wells at the Sweetwater Recharge Facility and analyzed for the presence of C. parvum and the potential indicator species . C. parvum was found in the surface water samples but was not present in the monitoring well water samples. Clostridium perfi-ingens was used as an indicator species because of its comparable characteristics. Clostridium perfringens was found in one monitoring well water sample but not in the surface water samples. The results of this study suggest the effectiveness of the SAT process.
