Contaminants of Emerging Concern

Legend Technical Services, Inc. of St. Paul, Minnesota is on the forefront of research and development in analytical chemistry. We offer expertise and state-of-the-art instrumentation to aid public and private research on Contaminants of Emerging Concern (CEC). For additional information and pricing, contact us or call (651) 221-4064.


LEGEND offers low-level analysis of many contaminants to meet complex testing parameters. Recent additions to our CEC testing include PFAS Analysis in soil and groundwater as well as 1,4-Dioxane Low Level Analysis in water. LEGEND determines PFAS by liquid chromatography triple quadrupole mass spectrometer (LC/MS/MS) and 1,4-dioxane by high-resolution gas chromatography/mass spectrometry (GC/MS). By using specialized laboratory techniques, various contaminants can be measured in units as low as parts per trillion (ppt).
