Distributing the CCR for a Large Water System (>500 customers) Community public water systems that serve more than 500 people must mail a copy of their CCR to every customer and make an
attempt to provide the CCR to non-bill-paying customers, such as nursing home residents.
Surface Water, TOC, and Your CCR: Guidance for Public Water Systems If you treat surface water, find TOC (total organic carbon) information needed for your CCR in this guidance. TOC data and
the corresponding wording DO NOT appear in the CCR template we have developed for your system.
