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

Aquatic Toxicology (Bioassay) Laboratory

The highly qualified bioassay laboratory (one of only two U.S. Department of Defense accredited laboratories in the world) provides a full range of evaluation and testing services. 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
  • Sulfur hexafluoride tracer services 
  • Nonaqueous phase liquid (NAPL) mobility and hydrocarbon identification
  • Disinfection byproducts
  • Taste and odor-causing compounds
