Solids Pollutant Category

All parameters for suspended and settable solids. This category does not include chemical-specific solids, such as suspended copper. Section 3.3.2 of the Technical Users Background Document for the DMR Pollutant Loading Tool describes how the Loading Tool identifies solids parameters and calculates the total solids load.

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