DeKalb County Releases 2026 Drinking Water Quality Report

County Surpasses State and Federal Standards

The DeKalb County Department of Watershed Management (DWM) has released its 2026 Drinking Water Quality Report, also known as the Consumer Confidence Report (CCR). The report confirms that DeKalb County continues to exceed all state and federal drinking water quality standards, delivering safe, high-quality drinking water to its customers. 

Serving more than 780,000 residents, DWM is responsible for not only treating and distributing drinking water, but also collecting and treating wastewater across DeKalb County. In accordance with regulatory requirements, DWM rigorously tests the county’s tap water to ensure it meets or exceeds water quality standards.

To maintain this high standard, DWM collects and tests more than 250 water samples each month from various points throughout the distribution system. In addition, the department performs 45 production control tests daily—365 days a year—to monitor water quality in real time.

The 2026 CCR includes detailed data from water quality testing conducted throughout 2025. It is available on DWM’s website at www.dekalbwatershed.com and is being shared via community and social media platforms including Nextdoor, Facebook, and X (formerly known as Twitter).
