Permittees are responsible for having their laboratory(ies) test wastewater analytes that are both in their NPDES permit and included in Study 34. For required Whole Effluent Toxicity (WET) tests, permittees must participate even if the test conditions (e.g., temperature, time of acute test, synthetic seawater matrix, etc.) in the permit do not exactly match those in Study 34. Refer to "WET Testing Laboratory Instructions" (page 5) for more information.
