Review Consumer Confidence Data







The report you are about to generate is designed to present the data you will need to assist with
creating a regulation-compliant Consumer Confidence Report (CCR). It does not, in and of itself,
satisfy the complete requirements of the Consumer Confidence Rule. You may wish to use EPA's CCR iWriter
tool to produce a regulation-compliant Consumer Confidence Report.  http://www.ccriwriter.com

IMPORTANT NOTICE: The CCR computer generated report for calendar year 2017 is now available. Check the data closely and contact the IEPA with any errors found.

The 2018 CCR is required to be delivered to customers by July 1, 2018.

If you had a Level 1 or Level 2 Revised Total Coliform Rule Assessment during 2017, you are required to add special language.
See the Sample Collector’s Handbook Chapter 3, Section 8.

If your supply had a violation during 2017, you are required to add an explanation and/or corrective action taken.
See SCHB, Chapter 2 CCR Page 10

Please note the following from the Sample Collectors Handbook:

  1. If your supply purchases water, you are required to include detections from your source water supply. See SCHB, Chapter 2 CCR Page A-1
  2. If you are going to use the CCR to satisfy Public Notice requirements for a violation, See SCHB, Chapter 2 CCR Page 19
  3. If you monitored for cryptosporidium in 2017, See SCHB, Chapter 2 CCR Page 8
  4. If you monitored for UCMR contaminants in 2017, See SCHB, Chapter 2 CCR Page 16
  5. If you receive an E. coli indicator-positive ground water source sample in 2017, See SCHB, Chapter 2 CCR Page 9,
