The Laboratory Guidance and Whole Effluent Toxicity (WET) Test Review Criteria document provides the regulatory context for WET testing and related services provided by labs. Having an understanding of the purpose of WET testing in Washington State can help labs provide better service to.

If the objective of the test is to determine the toxicity of an effluent in the receiving system, a local receiving water is recommended for use as dilution water provided that the receiving water meets specific.

The NELAC Institute (TNI) is a (c)(3) non-profit organization whose mission is to foster the generation of environmental data of known and documented quality through an open, inclusive, and transparent process that is responsive to the needs of the community.

The organization is managed by a Board of Directors and is governed by organizational Bylaws. Whole effluent toxicity tests should not be used alone, as inflexible guidance (i.e., as set in stone), without consideration of site‐specific conditions, and without thought.

However, compared to measurements of resident communities, WET tests have a major advantage: they can be adjusted based on site‐ and situation‐specific conditions Cited by: Home > Toxicity Testing.

Toxicity Testing Glossary Definitions for the most common industry terms. Sprague () prepared an extensive review of studies that compared toxicity test results to receiving-water impact, and concluded that effects measured in sublethal toxicity tests correlate with environmental effects most of the time, especially if water collected upstream of the effluent discharge is used as the control/dilution water.

short-term chronic test estimates the toxicity of an efflu-ent by exposing test organisms to different concentrations of effluent. The test results are based on survival and reproduction of the organisms using static renewal system.

This report and the accompanying video describe how the test is set up, initiated, monitored, renewed, and termi. Whole effluent toxicity (WET) is a direct measure of the toxicity of an effluent, using the survival, growth or reproduction of biological organisms as the test endpoint.
