Cryptosporidium & Giardia

WaterOne constantly monitors water quality to identify and remove undesirable microbes like Cryptosporidium and Giardia. These microbes most commonly seep into rivers, lakes, and streams as runoff from high concentrations of animal fecal matter. They have the potential to cause gastrointestinal irritation in humans.

Fortunately, WaterOne's rigorous treatment process removes harmful microbes like Cryptosporidium and Giardia, meeting and exceeding regulatory standards as well as our customers' high expectations for safe, reliable water.

Public safety is our priority. If WaterOne detects these or any other harmful substance in the water supply, we are required by law to notify the public. To ensure we reach you with important information about water quality and your water service, sign-up for Notify JoCo.
