Analytical Chemistry and Toxicology

Analytical Chemistry and Toxicology

KLI offers analytical chemistry and aquatic toxicology services for environmental, regulatory compliance, and hazardous waste studies. Specifically, KLI offers comprehensive laboratory services for the chemical analysis of contaminants in soils and sediments, sludges, water, and tissues. Toxicological services include acute and long-term aquatic toxicity testing for freshwater and marine species and product testing under Good Laboratory Practices (GLP) standards. The capacity of handling both chemical and toxicological analyses within our laboratories allows us to perform multidisciplinary programs such as toxicant characterization studies, Toxicity Identification Evaluations (TIE), and Toxicity Reduction Evaluations (TRE). KLI's laboratories utilize a rigorous Quality Assurance/Quality Control (QA/QC) program. Strict sample tracking and chain of custody procedures are followed in the laboratory as required by EPA, FDA, or RCRA. EPA, ASTM, or COE-specified and state-approved methods are used as appropriate for organic and inorganic analyses and toxicological testing.

Analytical Chemistry

KLI's laboratories offer the capability of performing routine analyses of soils, sediments, sludges, water, and tissues. Laboratory facilities include state-of-the-art instrumentation such as gas chromatograph/mass spectrometers and atomic absorption spectrophotometers. Services include:

Analyses of hazardous materials, effluents, wastewater, sludges, and industrial discharges for priority pollutants
Ability to handle soil, estuarine and marine sediment, water, seawater and tissue (bioaccumulation) matrices
Determination of fuel and solvent concentrations in various matrices
Pesticide analyses for both agricultural and environmental applications
Trace metals analyses in a metals-free clean laboratory, using ultra-low detection limits for both seawater and fresh water samples
Chemical analysis of drinking water
Agricultural support and consulting: analyses of nutrients, soil, water quality, and composting products
Specialty analyses of organotins and PCTs at very low detection limits using marine waters, sediments, and tissues
Dredge material testing using EPA and U.S. Army Corps of Engineers special protocols
The use of standard EPA methods for gas chromatographic analysis of organic contaminants in various matrices
Field sampling capabilities to address leaking underground storage tanks including on-site soil vapor analyses
Solid waste characterization: Experience with CAM and EP/TCLP procedures on soil and sediment samples, sludges, and other materials

Toxicological Testing

KLI offers 15 years of experience in aquatic toxicology using a wide range of life stages of marine, estuarine, and fresh water species. Testing is performed following state and federal standardized protocols. In addition, we perform bioassay testing adhering to strict GLP requirements for product testing. KLI has the experience and ability to conduct bioassays for testing water, sediments, soils, sludges, and other materials, including:

Dredged material according to EPA and COE Tier I, II, and III "Green Book" protocols
Industrial and municipal effluents
Drilling fluids and produced waters
Nonpoint source environmental samples such as agricultural drain water and urban runoff samples
Hazardous materials testing according to California 22 protocol
Aquatic GLP testing of industrial products

KLI's toxicological laboratories provide:

Three-species effluent characterization
Sediment solid phase, suspended phase, and elutriate bioassays
Phase I, II, and III Toxicity Identification Evaluation (TIE) and Toxicity Reduction Evaluation (TRE) testing
Sediment and water quality evaluations
Commercial product testing
Culture capabilities for marine crustaceans, molluscs, and polychaetes
Microtox™ Testing
Mobile bioassay trailers for on-site effluent evaluation and bioaccumulation studies
U.S. EPA intercalibration testing
