TestAmerica Corvallis

TestAmerica Corvallis provides solutions for our clients’ most difficult problems.  If you have questions about our capabilities, please contact Kathy McKinley (TestAmerica Corvallis) at 541-243-0974. 

TestAmerica Corvallis is staffed by scientific professionals who support some of the most technically challenging projects around the world.  The laboratory offers a broad range of capabilities with an emphasis on treatability and process engineering studies and aquatic toxicity testing. 

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

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
  • Evaluation of Uncontrolled Releases

Specialty Laboratory Services

In addition to providing standard analytical testing to support environmental remediation projects, pilot testing, and routine monitoring, the laboratory provides specialty testing for the following:

  • PFAS water treatment studies
  • Flame retardants in wastewater
  • Pore water generation
  • Nonaqueous phase liquid (NAPL) mobility and hydrocarbon identification
  • Disinfection byproducts
  • Geotechnical characterization of soils (sieve analysis, grain size, bulk density, etc.)
