Providing Quality Water

Terry Ranch Water Will Be Safe

Our certified water professionals conduct rigorous testing and analysis when a new water source is acquired. We identify the best treatment process to ensure safe drinking water for our community. Before purchasing the Terry Ranch aquifer water, Greeley researched to ensure the water met the city's high-quality standards. City engineers and independent experts collected over 7,000 water quality data points and analyzed the water for more than 575 contaminants. The studies proved the water is safe. For more information on these studies, reports, and independent resources, please contact Greeley’s Water Quality Program at (970) 336-4097.

Treatment Removes Contaminants

Uranium is a naturally occurring element commonly found in small quantities in plants, rocks, soil, water, and animals. While the Terry Ranch aquifer water contains low levels of uranium, we can remove this element easily during the treatment process. Greeley already removes uranium and contaminants from other water sources every day.

We will treat Terry Ranch water using an ion exchange process that works like a water softener. The city performed a 30-day pilot test using ion exchange treatment processes, proving this method can effectively remove uranium to non-detectable levels.

Listen to Laurie Sullivan, a senior project manager with Brown and Caldwell in Denver, explain the ion exchange treatment process:
