The biological condition of Cox’s Creek and Cox’s Rivulet: November 2002

Abstract

The condition of Cox’s Creek and Cox’s Rivulet downstream of the Scottsdale WWTP discharge was assessed by conducting a biological survey of aquatic macroinvertebrates in early November 2002. This survey was designed to provide a picture of the condition of the receiving streams for the Scottsdale WWTP discharges in comparison with state-wide standards derived from a large database of minimally polluted reference sites. Four other local control stream sites were also sampled for comparison, in Hurst Creek and Tuckers Rivulet. Macroinvertebrates samples were collected using a standard kick sampling technique, hand sorted and the fauna identified and counted prior to data analysis.
