NOTE 1: Systems susceptible to asbestos contamination due
				  solely to 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. 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.
