Study
- Citation
- Berretta, C., & Sansalone, J. (2011). Speciation and Transport of Phosphorus in Source Area Rainfall–Runoff. Water, Air, & Soil Pollution.
- Study description
- This study examines the speciation of phosphorus in rainfall and runoff from a paved surface. The study looked at the event based loads and the dissolved and particulate fractions of phosphorus in runoff.
Response
- Cause term/trajectory
-
Water quality - pH
(Increase)
- Cause description
- Increased pH between 6 and 8.5
- Effect term/trajectory
-
Water quality - nutrients (phosphorus)
(Change)
- Effect description
- Change in phosphorus speciation. The dominant species found in the stormwater was orthophosphates and it was found to be largely driven by the pH - as pH increased, so too did the orthophosphate presence.
