Fecal Coliform
9.1
Constituents of Concern: Fecal Coliform Bacteria Reason for Listing: Standard Violations Applicable Water Quality Standard for Class B Waters: • Fecal coliform shall not exceed a geometric mean of 200/100 ml (membrane filter count) based upon at least five consecutive samples examined during any 30 day period, nor exceed 400/100 ml in more than 20 percent of the samples examined during such period.
TMDL Development Analysis/Modeling: Load duration curves are based on cumulative frequency distribution of flow conditions in the watershed. Allowable loads are average loads over the recurrence interval between the 95th and 10th percent flow exceeded (excludes extreme drought (>95th percentile) and floods (
