How to Read the Table

GREEN: Better than average water quality compared to other sites in the watershed

BLACK: Average water quality compared to other sites in the watershed or N/A

RED: Worse than average water quality compared to other sites in the watershed

GRAY: The average value from all sites in the watershed. Useful for comparison.

*All averages are arithmetic means, except for E. Coli and/or Fecal Coliform, which are calculated as geometric means. For purposes of calculating a mean, values that exceed the measurement limit (e.g., <0.05, 60+, <33) are assumed to be 20% greater or less than their limit (e.g., 0.04, 72, 26.4).

Water Quality Standards

For 25.7% of the data records, Nitrate+Nitrite exceeded 10 mg/L. 10 mg/L represents the U.S. Public Health Service recommended limit of 10 mg/L NO3-N (nitrate-nitrogen) in drinking water.

For 42.9% of the data records, E. coli bacteria exceeded 235 CFU/100 ml. 235 CFU/100 ml represents Iowa's single sample maximum water quality standard for primary contact recreational use (Class A1), secondary contact recreational use (Class A2), and children's recreational use (A3).
