Study
- Citation
- Richards, S., Withers, P. J., Paterson, E., McRoberts, C. W., & Stutter, M. (2017). Removal and attenuation of sewage effluent combined tracer signals of phosphorus, caffeine and saccharin in soil. Environmental Pollution.
- Study description
- This study investigated the attenuation of phosphorus, caffeine and saccharin resulting from septic tank effluent. This was investigated through adsorption and desorption experiments.
Response
- Cause term/trajectory
-
Effluent - sewage
- Cause description
- Attenuation of phosphorus from septic tank effluent within soil
- Effect term/trajectory
-
Water quality - nutrients (phosphorus)
(Decrease)
- Effect description
- Adsorption of phosphorus in soil results in removal of phosphorus prior to discharge to environment
- Response measure type
- Other
- Response measure description
- This study used the soil distribution coefficient (Kd) as the measure of adsorption of the contaminant. The contaminant adsorption and desorption was measured over time.
