The Drinking Water Branch has two compliance sections that are in charge of implementing the Safe Drinking Water Act (SDWA) rules and regulations applicable to approximately 4,043 active Public Water Systems (PWS). The Revised Total Coliform Rule (RTCR) & Compliance Support Section is responsible for implementing the Revised Total Coliform Rule and also maintaining inventory information. The Chemical & Surface Water Compliance Section is responsible for implementing the SDWA regulations in regards to Chemical rules and the Surface Water Treatment Rule. Staff utilize the Safe Drinking Water Information System (SDWIS)/State database to update, manage, and evaluate the rules and regulations in order to determine compliance with a system’s monitoring and reporting requirements. Reviewers provide guidance to ensure systems are in compliance. Systems that do not comply are referred to the Enforcement Section for formal enforcement action. The Total Coliform and Compliance Support section also offers the Small Systems Laboratory Assistance Program (SSLAP) [PDF]to provide free laboratory analysis of Total Coliform and Nitrate for Government and Nonprofit Public Water Systems that serve a population of 100 or less.The results are used to determine compliance.
Starting April 1, 2016, the Revised Total Coliform Rule (RTCR) went into effect for all Public Water Systems in the state.

Electronic Sample Entry (eSE)
- What is the electronic Sample Entry (eSE) application?
- The eSE application can be used by laboratories that process drinking water sampling results that would like to report the sampling results electronically using IDEM’s eSE application. Submission of drinking water sampling results electronically is an alternative to using paper forms to fulfill reporting requirements.
- ESE is Live!
- As of October 1st, 2015, certified Laboratories are able to submit and report drinking water sampling results electronically.
- Are you a certified Laboratory that would like to use the eSE application?
- If you are interested in using the eSE application, you will first need to submit the eSE subscriber agreement form to IDEM. The eSE Subscriber Agreement Form is available on the IDEM Forms page.
