Consumer Confidence Report iWriter Updated with RTCR Requirements

On April 6, EPA deployed a revised version of the Consumer Confidence Report (CCR) iWriter with the RTCR requirements. The CCR iWriter is a tool that enables community water systems (CWS) to produce a regulation compliant Consumer Confidence Report (CCR). For the 2017 CCRs (with data from 2016), Community Water Systems (CWSs) must include information and data for both the Total Coliform Rule (TCR) and RTCR. The CCR iWriter was revised to include applicable requirements for both the TCR events (through March 31, 2016) and the RTCR events (on or after April 1, 2016).  The TCR aspects of the CCR iWriter will be removed in 2018.
