A colour-matched control was not considered necessary owing to the pale colour of the sample Source of Test Organisms: CSIRO Culture CS-327 (axenic laboratory culture) Test Initiated: 13 May 2008 at 1330h Summary of Test Method: The test temperature was 25 ± 1 o C. The test vessels were 20mL borosilicate glass scintillation vials with 20mL test solution. There were 4 replicate vessels per treatment. The initial cell density was 10,000 cells/ ml, determined by haemocytometer counts. Cell densities were enumerated at 72 hours by haemocytometer counts. The test vessels were shaken by hand 2 times per day.

The percent saturation of dissolved oxygen was determined to be 32% in this affected replicate vessel. QA/QC Parameter Criterion This Test Criterion met?

The sample was centrifuged prior to testing to remove particulates. Sample Physico-chemistry Comments ph ms/cm DO (%) E08074 (As received) Light brown coloured solution E08074 (Centrifuged) Light brown coloured solution = Salinity; ms/cm = Conductivity; DO = dissolved oxygen Test Method: This test measures the decrease in light output of the marine bacterium Vibrio fischeri after exposure to the sample for 5-, 15- and 30-min. The toxicity is expressed as the concentration of sample that causes a 50% reduction in the light output of the bacteria (EC50 value). The lower the EC50, the more toxic the sample. The 90% Test Protocol was used, with MOAS adjustment (Azur Environmental, 1998). Eight concentrations of each sample (27-90%) were tested (each in duplicate) using 2% NaCl as the diluent and control water. Exposure duration was 5, 15 and 30 minutes. The lowest observable effect (LOEC) and no observable effect (NOEC) concentrations were calculated using Bonferroni s t-test (ToxCalc Version , Tidepool Software). Phenol was also tested for quality assurance purposes.

8 Page 2 of 14 Results: The NS Outfall sample was not toxic to the bacterium, with no significant inhibition observed at any concentration tested. There was, however, significant stimulation (2-13% stimulation) of light output in most test concentrations following exposure for 5, 15 and 30 minutes.
