Sources of Pollution
In order to develop robust wetland treatment systems it is necessary to define and categorize the types of wastewater a system can treat.
- Stormwater – typically runoff of mineral and organic materials with intermittent flows.
- Agricultural Wastewater – runoff from intense agriculture with continous/intermittent flows.
- Industrial Wastewater – runoff and leachates from industrial processes with continuous/intermittent flows.
- Municipal Wastewater – continous flows from residential and commercial sources.
Each of these sources may overlap one another depending on the circumstances.
