5.3.3 Toxicity Testing
In order to obtain coopration of the processing facilities to permit sampling on site for
toxicity, it was agreed to report the toxicity information without direct reference to the site.
For this reason toxicity data are reported as Facility A, B, and C.
Acute and chronic testing of effluent from Facility A, Facility B, and Facility C was carried out
between August 30 and October 20, 1993. Three samples of effluent were tested from Facility A and
Facility B, while four samples were tested from Facility C. As noted in the following table,
toxicity was assessed using rainbow trout (Oncorhynchus mykiss), Ceriodaphnia dubia (a
freshwater daphnid), Selenastrum capricornutum (a freshwater alga), and Photobacterium
phosphoreum (a luminescent bacterium). Rainbow trout and Ceriodaphnia testing was carried out
by EVS Consultants, Selenastrum testing by B.C. Research Corp., and Photobacterium testing
(using the Microtox method) by Integrated Resource Consultants Inc.
