Nutrient Aggregation Function
A function in the Advanced Search that can calculate aggregated phosphorus and aggregated nitrogen loads. Section 3.1.3 of the Technical Users Background Document for the DMR Pollutant Loading Tool describes how the Loading Tool performs nutrient aggregation.
Search Considerations: The Loading Tool calculates aggregated nitrogen and phosphorus loadings by selecting pollutant loadings associated with parameter codes in ICIS-NPDES and PCS that are on the nitrogen and phosphorus lists. These lists are available in the Technical Users Background Document for the DMR Pollutant Loading Tool.
