DEQ may require concurrent chemical-specific analyses on samples collected for WET testing purposes where there is reason to believe substances may cause or contribute to whole effluent toxicity. Permittees must submit the results of concurrent chemical-specific testing with the WET test report. Permittees must collect sufficient sample volumes for the testing laboratory to perform concurrent chemical-specific testing in addition to the WET testing.
