Safe Drinking Water Information System

The Safe Drinking Water Information System (SDWIS) Monitoring Schedules portal gives communities the ability to query those monitoring schedules specific to their water system. These schedules are used for the basis of monitoring requirements applicable to compliance-related activities.

The Safe Drinking Water Information System (SDWIS) Consumer Confidence Reporting (CCR) portal gives communities the ability to query those CCRs specific to their water system.

The CCR computer generated report for calendar year 2017 is not yet available. Estimated availability 3/15/2018. Please check back often as updates will be posted as time nears.

The 2018 CCR is required to be delivered to customers by July 1, 2018. This date cannot be extended regardless of when the Illinois EPA computer generated report is available. It is recommended that you proceed on your own in generating the CCR if you need a lot of lead time to meet the July 1st deadline.

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 your supply had a violation during 2017, you are required to include an explanation. See SCHB, Chapter 2 CCR Page 10
  3. If you are going to use the CCR to satisfy Public Notice requirements for a violation, See SCHB, Chapter 2 CCR Page 19
  4. If you monitored for cryptosporidium in 2017, See SCHB, Chapter 2 CCR Page 8
  5. If you monitored for turbidity in 2017, See SCHB, Chapter 2 CCR Pages 16 and B-2
  6. If you monitored for UCMR contaminants in 2017, See SCHB, Chapter 2 CCR Page 16
  7. If you receive an E. coli indicator-positive ground water source sample in 2017, See SCHB, Chapter 2 CCR Page 9,
  8. If your system had to complete a Level 1 or Level 2 Assessment under the Revised Total Coliform Rule, there is mandatory language that must be added to the CCR.
