and for all water systems. Complete records must be made available to the
department upon request.
(2) A
supplier shall keep a daily record of the samples and control tests required in

softening, or filtration shall keep a daily record of the operations performed
in the treatment process together with measured flows, phenolphthalein (p)
alkalinity, total alkalinity, hardness (where softening is utilized), chemical
doses, observations, and costs related to the operation of the plant.
