The city is revising its measurement of the nitrate levels in the Shadow Ridge well system, which currently serves nearly 500 residents in Greely, after Metro reported that rising toxicity in the well had remained largely unaddressed.

At Tuesday's Environment and Climate Protection Committee meeting, staff corrected their own report which, when released a week earlier, stated that nitrate levels in the well had reached 5.1 mg/L. According to updated figures, the well contains only 4.5 mg/L of nitrates — still within the acceptable limit for safe consumption, but reflecting a steady increase since 2008.
