(1) REPORTING.
(a) Water suppliers shall report all of the
				  following information for each monitoring location to the department no later
				  than 10 days after the end of any quarter in which monitoring is required:
1. Number of samples taken during the
				  quarter.
2. Date and results of
				  each sample taken during the quarter.
3. Arithmetic average of quarterly results
				  for the four quarters immediately previous for each monitoring location (LRAA),
				  beginning at the end of the fourth calendar quarter that follows the compliance
				  date and at the end of each subsequent quarter. If the LRAA calculated based on
				  fewer than four quarters of data would cause the MCL to be exceeded regardless
				  of the monitoring results of subsequent quarters, the water supplier shall
				  report this information to the department as part of the first report due
				  following the compliance date or anytime thereafter that this determination is
				  made. If the public water system is required to conduct monitoring at a
				  frequency that is less than quarterly, the water supplier shall make compliance
				  calculations beginning with the first compliance sample taken after the
				  compliance date, unless the public water system is required to conduct
				  increased monitoring under s.
				  NR
				  809.63(2).
4. If the MCL for TTHM or HAA5s was violated
				  at any monitoring location.
5. Any
				  operational evaluation levels that were exceeded during the quarter and, if so,
				  the location and date, and the calculated TTHM and HAA5 levels.

				  state laboratory results. The fluoride concentration obtained by the operator
				  shall be noted on the data sheet prior to submission to the state
				  laboratory.
3. For public water
				  systems with large distribution systems and multiple sources, more than one
