This document presents results from a 48-hour acute toxicity test conducted in February 1999 for the Port of Seattle, exposing water fleas (Ceriodaphnia dubia) to copper-contaminated water collected from Miller Creek. The test found that all organisms survived at concentrations up to 50 micrograms per liter, while complete mortality occurred at concentrations of 100 micrograms per liter and above. Water quality parameters including pH, dissolved oxygen, and specific conductivity were monitored throughout the test period.
