Every year, Summerville CPW publishes a Consumer Confidence Report. The 2026 CCR covers testing data from the prior year and tells you what's in your tap water by the numbers. I'm walking through it on camera this week, page by page.
What the CCR covers
The CCR lists every regulated contaminant CPW tested for, the detected levels, the federal Maximum Contaminant Level, and the range across the system. It's a public document. You can request a copy from CPW or download it from their website.
The numbers that matter for Summerville residents
CPW's hardness runs around 7.2 grains per gallon. The EWG database flags 11 contaminants above their health advisory guidelines, including total trihalomethanes at roughly 168 times and haloacetic acids at approximately 368 times the EWG advisory levels. These are legal under EPA standards.
CPW uses chlorine as its primary disinfectant. The 2026 CCR will show chlorine residual levels and disinfection byproduct readings. CPW is investing $43.5 million of a $96 million treatment upgrade focused on the treatment process.
The 18-minute video
I'm reading the actual CCR PDF on camera with annotations. Every number I cite is on-screen with the source document visible. No interpretation without citation.
Watch the video, then call (843) 302-5720 if you want a free test to compare your tap's numbers to what the CCR reports system-wide.
