  • TRC = To1.al Residual Chlorine tsamples were collected in two 2.5 gallon cubitainers. Temperature was measured in each cubitainer upon arrival.
4. Sample Manipulation: Samples from Outfall 101 and intake were warmed to test temperature (25.0 +/- l.0°C) in a warm water bath.

Aliquots of Outfall IOI and Intake samples were UV-treated through a 40-watt Smart UV Sterilizer (manufactured bv Emperor Aquatics, Inc.) for 2 minutes.

SUMMARY

/CONCLUSIONS

Exposures to samples collected September 11 - 16, 2022 from Outfall 10 I resulted in no toxic effects to fathead minnows or daphnids. The resulting IC2s values, for both species, were > I 00 percent. Exposure of minnows and daphnids to intake samples resulted in no significant differences from the controls during this study period.
