nitrite, and nitrate monitoring results if chloramines are used in
the water system; and
(x) the records of treatment effectiveness monitoring
for systems using reverse osmosis or nanofiltration membranes. Treatment
effectiveness monitoring includes the parameters for determining when
maintenance is required. Examples of parameters to be monitored include
conductivity (or total dissolved solids) on each membrane unit, pressure
differential across a membrane vessel, flow, flux, and water temperature.
At a minimum, systems using reverse osmosis or nanofiltration membranes
must monitor the conductivity (or total dissolved solids) of the feed
and permeate water once per day.
(C) The following records shall be retained for a period
of five years after they are no longer in effect:
(i) the records concerning a variance or exemption
granted to the system;
(ii) Concentration Time (CT) studies for surface water
treatment plants;
(iii) the Recycling Practices Report form and other
records pertaining to site-specific recycle practices for treatment
plants that recycle; and
(iv) the turbidity monitoring results and exception
reports for individual filters as required by §290.111 of this
title.
(D) The following records shall be retained for at
least five years:
(i) the results of microbiological analyses;
(ii) the results of inspections (as required in subsection
(m)(1) of this section) for all water storage and pressure maintenance
facilities;
(iii) the results of inspections (as required by subsection
(m)(2) of this section) for all pressure filters;
(iv) documentation of compliance with state approved
corrective action plan and schedules required to be completed by groundwater
systems that must take corrective actions;
(v) documentation of the reason for an invalidated
fecal indicator source sample and documentation of a total coliform-positive
sample collected at a location with conditions that could cause such
positive samples in a distribution system;
(vi) notification to wholesale system(s) of a distribution
coliform-positive sample for consecutive systems using groundwater;
(vii) Consumer Confidence Report compliance documentation;
(viii) records of the lowest daily residual disinfectant
concentration and records of the date and duration of any failure
to maintain the executive director-approved minimum specified disinfectant
residual for a period of more than four hours for groundwater systems
providing 4-log treatment;
(ix) records of executive director-specified compliance
requirements for membrane filtration, records of parameters specified
by the executive director for approved alternative treatment and records
of the date and duration of any failure to meet the membrane operating,
membrane integrity, or alternative treatment operating requirements
for more than four hours for groundwater systems. Membrane filtration
can only be used if it is approved by the executive director and if
it can be properly validated;
(x) assessment forms, regardless of who conducts the
assessment, and documentation of corrective actions completed or documentation
of corrective actions required but not yet completed as a result of
those assessments and any other available summary documentation of
the sanitary defects and corrective actions taken in accordance with §290.109
of this title (relating to Microbial Contaminants) for executive director
review;
(xi) seasonal public water systems shall maintain executive
director-approved start-up procedures and certification documentation
in accordance with §290.109 of this title for executive director
review; and
(xii) records of any repeat sample taken that meets
the criteria for an extension of the 24-hour period for collecting
