Pathogen Indicators Pollutant Category

All parameters for total coliform, streptococci, and enteric. The Pathogen pollutant category query in EZ Search is the only query option for users to view discharges of pathogens. Because these parameters are reported in units that cannot be expressed as a mass discharge (count per 100 mL), they are excluded from all other Loading Tool searches. Section 3.3.2 of the Technical Users Background Document for the DMR Pollutant Loading Tool describes how the Loading Tool identifies pathogen indicator parameters and calculates the pathogen indicator discharges.

Search Considerations: The Loading Tool selects pollutant measurements for the Pathogen Indicators category if the measurements are associated with parameter codes in ICIS-NPDES and PCS that are on the pathogen indicators list. This list is available in the Technical Users Background Document for the DMR Pollutant Loading Tool.
