Organic Geochemistry Research Lab
(OGRL)
The U.S. Geological Survey (USGS) Kansas Water Science Center Organic Geochemistry Research Laboratory (OGRL) was established in 1987. The OGRL is a multidisciplinary program that contributes knowledge about the distribution, fate, transport, and effects of new and understudied organic compounds that may affect human health and (or) ecosystems.
The OGRL consists of two units: Algal and Other Environmental Toxins (AET) Unit and Environmental Organic Chemistry (EOC) Unit. The OGRL does independent and collaborative research, develops robust analytical methods, and provides fee-for-service analytical laboratory analyses.
Algal and Other Environmental Toxins Unit
The Algal and Environmental Toxins Unit has the capability to detect toxins that could be harmful to human health and the environment.
-
Enzyme-linked immunosorbent assay (ELISA) techniques in low and high salinity waters for the following toxins: anatoxin-a, cylindrospermopsin, microcystin, and saxitoxin.
-
Liquid chromatography/high resolution mass spectrometry for the following:
-
Total and dissolved freshwater toxins (includes 13 analytes)
-
Total and dissolved marine toxins (includes 9 analytes)
-
Total and dissolved freshwater and marine toxins (includes 21 analytes)
- Nontarget screening
-
Environmental Organic Chemistry Unit
Using state-of-the-art instrumentation and techniques, the Environmental Organic Chemistry Unit analyzes samples from various matrices to determine the occurrence of organic contaminants in the environment.
-
Sample preparation, including filtering, accelerated solvent extractions, bioassay extractions, and solid-phase extractions.
-
Liquid chromatography/tandem mass spectrometry methods in water and solids (soil, sediment, and biosolids) for the following:
-
Artificial sweeteners (includes 5 analytes)
-
Atrazine
-
Glyphosate, aminomethylphosphonic acid (AMPA), and glufosinate
-
Four class antibiotic method (includes 33 analytes)
-
