Water Quality Parameter Water Quality Limit – Food Crop Irrigation Water Quality Limit – Restricted Access Irrigation Water Quality Limit – Unrestricted Access Irrigation
Total Coliform 2.2 total coliform 23 total coliform/100mL 2.2 total coliform/100mL
Fecal Coliform No Detect/100mL (some states prohibit usea) 200 fecal coliform/100mL No Detect/100mL – 20 fecal coliform/100mL
E. coli N/A 126 E. coli/100mL (only CO uses E. coli as a standard) 126 E. coli/100mL (only CO uses E. coli as a standard)
Turbidity 2 NTU N/A 2 NTU – 3 NTU
TSS N/A 20-30 mg/L 5 mg/L
BOD 10 mg/L BOD 20-30 mg/L 5-10 mg/L
CBOD N/A 15-20 mg/L 5-20 mg/L
pH N/A N/A N/A

Note: Many of these standards are based on water quality limits established for reclaimed water (treated wastewater), not stormwater specifically
