Disinfectant residuals, disinfection byproducts and disinfection byproduct precursors. Samples will be collected according to the approved sample site plan. A system using chlorine dioxide will collect one sample daily at the entry point to the distribution system. If a daily sample exceeds the maximum residual disinfectant level of 0.8 mg/L, the system shall collect a three-sample set in the distribution system within 24 hours. The three-sample sets must include one sample near the first customer, one sample reflecting average residence time and one sample reflecting maximum residence time if the system does not booster chlorinate at a site near the first customer at least six hours apart. An acute violation occurs with a distribution sample exceedance following a daily sample exceedance. A nonacute violation occurs with two consecutive daily sample exceedances.
