Editing Urban stormwater pathogen load (section)

== Aggregation Semantics ==
Geographic aggregation of urban stormwater pathogen load involves summing pathogen loads across defined urban catchments or drainage basins to represent total pathogen transport within those areas. Temporal aggregation may vary depending on monitoring design but often includes event-based, seasonal, or annual summations to capture variability in pathogen loads associated with precipitation patterns and urban activity.

Cross-signal aggregation considers the integration of urban stormwater pathogen load with related signals such as combined sewer overflow discharge volume and extreme precipitation intensity. This allows for comprehensive assessment of factors influencing pathogen transport and the potential impacts on waterborne disease incidence rates. Aggregation semantics support multi-scale analysis from local stormwater systems to broader urban watershed contexts.
