Science, Health & Safety

As the largest water system in Kansas, WaterOne's priority is producing high-quality water. Our customers rely on us to take the quality and safety of our water very seriously. It's a responsibility we deliver on.

WaterOne tests for over 100 regulated and unregulated contaminants in the drinking water. Each year, more than 18,000 samples are collected and nearly 120,000 tests are conducted to ensure our water is clean and safe. WaterOne closely monitors the volume and quality of its water supply, and before it reaches your tap it's been meticulously filtered and treated. 

See our Water Quality Reports for the latest data about our water, and read on to learn more about the minerals, metals, and other substances that are checked for in drinking water.
