Abstract:

In order to study the effects of phosphorus (P) reduction at the John E. Egan Water Reclamation Plant (Egan WRP), the Metropolitan Water Reclamation District of Greater Chicago reduced the effluent P concentration to 0.5 mg/L.

Water, sediment, biological, and physical habitat data were collected from 3 stations in Salt Creek before and after P reduction. Mean total P (TP) downstream of the Egan WRP decreased from over 2 mg/L to 0.3 mg/L.

Sestonic chlorophyll a (chl-a) concentrations were highest upstream of Egan WRP, and were diluted by effluent. Before and after P reduction, algae was not limited by nutrient concentrations, but likely by light availability and residence time. Diel fluctuations of dissolved oxygen (DO) occurred at all three stations, before and after the P reduction.

There was no apparent stream response to lower P in the water column. There were no correlations between chl-a, TP, or turbidity.
