Findings > Non-metals

  • Aquatic Life Cold 1 standards were used to compare with analytical results for the five non-metals that apply in evaluating streams for classification as Colorado Outstanding Waters.

  • Also shown in the tables below are a comparison of total nitrogen and phosphorus (nutrients) with interim standards and results from additional sampling for bacteria concentrations.

  • The analytical results are from samples collected seasonally since summer 2020 at nine study area streams, the same shown in metals findings.

  • As evident from examining the tables below, only bacteria concentrations (E. coli and total coliform) on occasions at some streams were higher than the standards.
