Bioassay - WET Testing

SL provides a variety of industrial, mining and municipal clients with a full line of WET freshwater testing.

SL Biomonitoring Department specialize in biological assessments of freshwater habitats such as pond outfalls, streams, rivers, lakes, reservoirs and wetlands. Organisms are tested in an isolated photoperiod and temperature-controlled environment. The majority of the freshwater organisms utilized for testing are cultured in-house, but excellent relationships with vendors are maintained in order to provide timely testing for clients.

Tests include the 24-48 hour static screening tests that look only at the toxicity of a full-strength sample, and the 6-8 day chronic toxicity tests that not only look at survival, but encompass more subtle parameters such as growth rates and reproduction. Tests are conducted using walk-in environmental chambers that accurately control lighting, photo period, and test temperature.
