Nutrient-rich fertilizer runoff and sewage effluent can boost algae growth, which starves the water of oxygen, causing eutrophication.
Samples were collected from catchment waters, precipitation, dry deposition, agricultural fertiliser and sewage effluent.
The test water was artificial sewage effluent to simulate the infiltration of reused wastewater.
The use of treated sewage effluent in agriculture has been a current practice in several countries.
This, of course, lowers river levels, which could result in a higher percentage of sewage effluent in the water unless the water is properly treated.
