Systems susceptible to asbestos contamination due solely to source water shall monitor at every entry point to the distribution system during normal operating conditions. Systems susceptible to asbestos contamination due to both source water and corrosion of asbestos-cement pipe shall sample at a tap served by asbestos-cement pipe and under conditions where asbestos contamination is most likely to occur. NOTE 2: Systems shall measure the residual disinfectant level at the same locations in the distribution system where, and at the same time when, total coliforms are sampled. NOTE 3: Systems shall take routine daily samples at the entrance to the distribution system. Systems shall take additional three-sample sets in the distribution system at the following locations:

(a) If chloramines are used to maintain a disinfectant residual in the distribution system or if chlorine is used to maintain a disinfectant residual in the distribution system and there are no disinfection points after the entrance to the distribution system (i.e., no booster chlorination), the system shall take three samples as close to the first customer as possible at intervals of at least six hours.

(b) If chlorine is used to maintain a disinfectant residual in the distribution system and there are one or more disinfectant addition points after the entrance to the distribution system (i.e., booster chlorination), the system shall take one sample at each of the following locations: as close to the first customer as possible, in a location representative of average residence time, and as close to the end of the distribution system as possible. NOTE 4: Systems taking one sample shall take the sample at a location reflecting maximum residence time in the distribution system. Systems taking more than one sample shall take at least 25% of the samples at locations representing maximum residence time of the water in the distribution system and shall take the remaining samples at locations representing at least average residence time in the distribution system and representing the entire distribution system, taking into account number of persons served, different sources of water, and different treatment methods. NOTE 5: Systems shall take routine daily samples at the entrance to the distribution system. Systems shall take routine monthly or additional three-set samples in the distribution system; each three-set sample shall consist of one sample at each of the following locations: a location as close to the first customer as possible, a location representative of average residence time, and a location reflecting maximum residence time in the distribution system. NOTE 6: For initial base point monitoring, systems shall take four consecutive quarterly samples during the first three-year compliance period. If a system does not detect any VOC, it shall take one sample annually beginning with the next three-year compliance period. NOTE 7: During the first quarter of initial base point monitoring, GW systems shall take a minimum of one sample that is representative of each well. Under all other circumstances, systems shall sample at every entry point to the distribution system during normal operating conditions. NOTE 8: The minimum number of samples shall be as set forth in Rule 62-550.518(2), F.A.C. NOTE 9: Systems shall conduct repeat monitoring in accordance with Rule 62-550.518(7), F.A.C., and systems that routinely collect fewer than five samples per month shall collect at least five samples during the next month the system provides water to the public. NOTE 10: The Department shall waive the final two quarters of initial monitoring for a sampling point if the results of the samples from the previous two quarters are below the regulatory detection limit. Additionally, under the conditions described in Rule 62-550.519(1)(c), F.A.C., historical data may be used to satisfy initial monitoring requirements. NOTE 11: Quarterly monitoring for gross beta shall be based on the analysis of monthly samples or the analysis of a composite of three monthly samples. For iodine-131, a composite of five consecutive daily samples shall be analyzed once each quarter. Annual monitoring for tritium and strontium-90 shall be conducted by means of the analysis of a composite of four consecutive quarterly samples or analysis of four quarterly samples.
