(1) A public water system that uses a surface
			 water source and does not provide filtration treatment shall report monthly to
			 the Department the information specified in this paragraph beginning December
			 31, 1990, unless the Department has determined in writing that filtration is
			 required, in which case the Department may specify alternative reporting
			 requirements, as appropriate, until filtration is in place. A public water
			 system that uses a ground water source under the direct influence of surface
			 water and does not provide filtration treatment shall report monthly to the
			 Department the information specified in this paragraph beginning December 31,
			 1990, or 6 months after the Department determines that the ground water source
			 is under the direct influence of surface water, whichever is later, unless the
			 Department has determined, in writing, that filtration is required, in which
			 case the Department may specify alternative reporting requirements, as
			 appropriate, until filtration is in place.
(a) Source water quality information shall be
			 reported to the Department within 10 days after the end of each month the
			 system serves water to the public. Information that shall be reported includes:
(i) The cumulative number of months for which
			 results are reported.
(ii) The
			 number of fecal and/or total coliform samples, whichever are analyzed during
			 the month (if a system monitors for both, only fecal coliforms must be
			 reported), the dates of sample collection, and the dates when the turbidity
			 level exceeded 1 NTU.
(iii) The
			 number of samples during the month that had equal to or less than 20/100 ml
			 fecal coliforms and/or equal to or less than 100/100 ml total coliforms,
			 whichever are analyzed.
(iv) The
			 cumulative number of fecal or total coliform samples, whichever are analyzed,
			 during the previous six months the system served water to the public.
(v) The cumulative number of samples that had

(vi) The percentage of samples that had equal
			 to or less than 20/100 ml fecal coliforms or equal to or less than 100/100 ml
			 total coliforms, whichever are analyzed, during the previous six months the
			 system served water to the public.
(vii) The maximum turbidity level measured
			 during the month, the date(s) of occurrence for any measurement(s) which
			 exceeded 5 NTU, and the date(s) the occurrence(s) was reported to the
			 Department.
(viii) For the first 12
			 months of recordkeeping, the dates and cumulative number of events during which
			 the turbidity exceeded 5 NTU, and after one year of recordkeeping for turbidity
			 measurements, the dates and cumulative number of events during which the
			 turbidity exceeded 5 NTU in the previous 12 months the system served water to
			 the public.
(ix) For the first 120
			 months of recordkeeping, the dates and cumulative number of events during which
			 the turbidity exceeded 5 NTU, and after 10 years of recordkeeping for turbidity
			 measurements, the dates and cumulative number of events during which the
			 turbidity exceeded 5 NTU in the previous 120 months the system served water to
			 the public.
