Small Drinking Water Webinar Series 2023 Recap

EPA's Office of Research and Development (ORD) and Office of Water (OW), in collaboration with the Association of State Drinking Water Administrators (ASDWA), host this free webinar series to communicate the latest information on solutions for challenges facing small drinking water systems. The series topics vary each month and are primarily designed for state, territory, and tribal staff responsible for drinking water regulations compliance and treatment technologies permitting. We have compiled the webinar recordings that were released in 2023 as part of this series below:

The Small Drinking Water Systems Webinar Series is scheduled to continue in 2024. Some of the subjects that are likely to be featured this year include Lead Service Line Inventory Guidance, PFAS Treatment, Disinfection Byproducts, and many other topics.

Arsenic in Drinking Water

Arsenic is a heavy metal and a regulated contaminant in drinking water and wastewater effluent. In 2001, under the Arsenic Rule, EPA adopted a lower standard for arsenic in drinking water of 10 parts per billion (ppb) which replaced the previous maximum contaminant level (MCL) of 50 ppb. Arsenic is a semi-metal element in the periodic table. It is odorless and tasteless. It can enter drinking water supplies from natural deposits in the earth or from agricultural and industrial practices. 

We have 180 resources (and counting) on Arsenic in our Documents Database that provide valuable information on this topic. You can search for documents about the arsenic rule, complying with the arsenic maximum contaminant level, the reporting requirements for the annual Consumer Confidence Reports (CCR), and many other useful guides that will help you to deliver safe and clean water to utility customers. 

To access the wealth of Arsenic related knowledge within our database just select "CATEGORY" in the dropdown then choose "Arsenic." Once you make that selection, a second dropdown will appear where you can choose "HOST," “TYPE,” or “STATE” to narrow the search even further. If you have a specific search term in mind, use the “Keyword Filter” search bar on the right side of the screen.

This is part of our A-Z for Operators series.

Consumer Confidence Report Rule Revision Updates

Everyone has a right to know what is in their drinking water and where it comes from. That is why the original consumer confidence reports (CCR) rule was established in 1998 after amendments were made to the Safe Drinking Water Act in 1996. The goal of the reports is to provide community members with updated information about the state of their drinking water that is both accurate and accessible. These reports are also known as annual water quality reports and every community water supplier needs to submit one by July 1st each year. 

America’s Water Infrastructure Act of 2018 later called for an amendment to the rule that would require the U.S. EPA to revise CCR regulations, allow electronic delivery of CCRs, and require large systems to deliver CCRs twice a year. The U.S. EPA is currently in the process of revising the Consumer Confidence Report Rule. After meeting with various stakeholders about improving the effectiveness of communicating drinking water information, they identified five areas that could use improvement: 

1. CCR understandability,
2. Reporting MCLs in numbers greater than or equal to 1.0,
3. Reporting period for including a Tier 3 Public Notice (PN) in the CCR,
4. Certification of CCR delivery and content by the CWS to the primacy agency, and
5. Electronic delivery of the CCR.

The U.S. EPA is anticipating that the final rule should be released by March 2024. Many resources and documents are available on the U.S. EPA website about how to comply with CCR requirements.
