Anlab .w,rurncestwaofutrot►T r..i �..r Sparger Hazardous Waste Test: Samples AC19258, AC19259, AC19260 August 1993 Page ♦ 2 RESULTS Test results for sample AC19258 are summarized in Table 2. A review of the survival data shows that :here was 100% survival in the lab control at the end of the test. This result met the test acceptability criterion of at least 90% survival during the 96 hour exposure period. Representative control fish had a mean standard length of 8.6 mm (range 8.3 to 9.0 mm) and a mean wet weight of 0.0039 grams (range 0.0033 to 0.0048 grams). A review of the survival data for Sample AC19258 shows that there was 100% survival in the 750 mg/I and 250 mg/1 test treatments, and 95% survival in the 500 mgA test treatment at the 96 hour exposure period. The results of this screening assay indicate that the-LC50 is greater than 750 mg/I, and that 1.1 ie 5dmple should be classified as not ha:ardour under the CCR Title 26 Section 22 criteria. Test results for sample AC19259 are summarized in Table 3. A review of the survival data for Sample AC19259 shows that there was lo% survival In the 750 mg/I test treatment, 90%survival in the 500 mg/1 test treatment, and 100%survival in the 250 mg/1 test treatment at the 96 hour exposure period. The results of this screening assay indicate that the LC50 is greater than 750 mg/l, and that the sample should be classified as not hazardous under the CCR Title 26 Section 22 criteria. Test results for sample AC19260 are su,-nmarized in fable 4. A review of the survival data shows that there was 100% survival in the lab control at the end of the test. This result met the test acceptability criterion of at least 90%survival during the 96 hour exposure period. A roviow of the survival data for Sample AC:19?F0 shows that there Was 100% survival in the 750 mg/I, 500 mg/I, and 250 mg/1 test treatrrents at the 96 hour exposure period. The results of this screening assay indicate that the LC50 s greater than 750 mg/I, and that the sample should be classified as not hazardous under the C:CR Title 26 Section 22 criteria.
