Nautilus Environmental has two offices in the United States and one in Western Canada (Nautilus Environmental Company). We specialize in consulting in the areas of risk assessment, watershed management, site-specific water quality objective and criteria development, water effect ratio studies, toxicity reduction, regulatory representation and litigation support, and integration of biological, chemical, and toxicological data.

In support of these efforts, we conduct marine, freshwater, and terrestrial bioassays on a variety of sample types including sediments, soils, municipal and industrial effluents, stormwater runoff, chemical and agricultural products, and receiving waters. We also provide hazardous waste characterization for liquid and solid samples under California and Washington regulations.
