Editing Wastewater organic pollution load (section)

== Boundary Conditions ==
The boundaries of the wastewater organic pollution load signal include all organic matter discharged from municipal and industrial wastewater treatment systems into surface waters that contributes to oxygen demand. This encompasses both treated and untreated effluent releases that contain biodegradable organic compounds. Excluded from this signal are organic loads from non-wastewater sources such as natural organic matter from terrestrial runoff, atmospheric deposition, or in situ biological production within the water body. Additionally, discharges that do not contribute to oxygen demand, such as inorganic pollutants or non-biodegradable substances, are outside the scope of this signal.
