ASSESSING THE ECOSYSTEM IMPACT OF DRINKING WATER ORTHOPHOSPHATE ADDITION ON URBAN WATERSHEDS

Summary:

In collaboration with Dr. Emily Elliot this NSF Rapid Response Research project will assess changes in the microbial ecology, water chemistry and nutrient availability in water collected from DW pipes and hydrologically connected urban streams before and after PO4-3 addition in Pittsburgh.

The overall aims of the study are to:

  1. Determine the role of leaking infrastructure on urban stream nutrient and microbial dynamics.
  2. Document how PO4-3 additions influence microbial communities in hydrologically connected urban streams and potentially shift nutrient limitation and eutrophication potential.

This work is supported by an NSF RAPID grant (DEB-1929843)
