Treatability Research Laboratory

The Treatability Research Center specializes in bench scale treatment and technology development for water, wastewater, soil, and solids. Technologies are developed or evaluated, and processes are optimized to determine the most effective solution for meeting our clients’ project objectives. Treatability evaluations may include the following:

  • Jar testing and zeta potential analysis
  • Ozone treatment and/or advanced oxidation (AOP) treatment
  • Disinfection byproduct (DBP) formation potential tests
  • Rapid Small Scale Column Tests (RSSCT) for adsorptive media
  • Stabilization and solidification evaluations
  • In Situ Chemical Oxidation (ISCO) testing
  • Taste and odor treatment and analyses

Aquatic Toxicology (Bioassay) Laboratory

Eurofins TestAmerica Corvallis carries Oregon NELAP certification, with the ability to add additional certifications as needed. Our National Pollutant Discharge Elimination System (NPDES) / toxicity compliance experience spans a broad range of contaminants and aquatic environments (e.g., freshwater, estuarine, lake, stream, wetland, and tidal). The staff performs thousands of toxicity tests ranging from simple acute testing to lifecycle chronic and bioaccumulation studies. This experience includes testing over 40 different marine and freshwater vertebrate, invertebrate, algal, and plant species. Representative services include:

  • Toxicity Reduction Evaluations (TREs)
  • Toxicity Identification Evaluations (TIEs)
  • Whole Effluent Toxicity (WET) Tests
  • Toxicity Treatability Evaluations (TTEs)
  • Water Quality Based Effluent Limits (WQBELs)
  • Bioassay Testing and Chemical Analyses
  • Criteria Development
  • Permit Reviews and Evaluations
