Did you know that more than 70,000 analyses are run on Northglenn's drinking water every year?
The City of Northglenn water quality laboratory at the Water Treatment Facility is charged with ensuring that the city's drinking water meets all state and federal drinking water regulations. The water quality laboratory provides water sampling, monitoring, testing and reporting. Laboratory staff also responds to customer concerns and assists other city departments with water quality testing.
We are state-certified for 13 contaminants in drinking water. Water samples are analyzed from the rivers, canals, and lakes that feed our water system all the way through the treatment process, out to your home, and during and after the waste treatment process. We run about 30 different methods ranging from simple field measurements to complex organic analyses.

Zeolite, or resin beads, can escape from the water softener into the internal plumbing. This can happen even if the softener is not in use. Proper maintenance should prevent this issue. (Northglenn has only moderately hard water and in most instances, a water softener is not necessary.)
