RESULTS <br />3.1 Effects of the Waste Sample Designated "1000 E Channel Mixing Area Green Liquid <br />On Ground" on Fathead Minnows <br />The results of this test are summarized in Table 1. The LC5o of this sample was <250 mg/L, <br />which is less than the Title 22 "Hazardous Waste" classification threshold of 500 mg/L; <br />accordingly, this sample should be considered "hazardous" with respect to fish toxicity.
