PFASs are a large family of long-chain fluorinated chemicals used in many manufacturing and industrial applications, including fire suppression and oil, stain, grease, and water repellency. Among the many PFASs, perfluorooctoanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are the most commonly produced. A major use of PFASs was in fire extinguishing aqueous film forming foam [...]
The inhalation of indoor air contaminated with trichloroethylene (TCE) can cause direct health effects. It is paramount to monitor for acute and chronic TCE exposure with the best possible technologies that reach low-detection limits and provide timely, accurate data. OTIE’s scientists and engineers are getting ahead of the environmental industry’s curve on vapor intrusion (VI) [...]
Over the last two decades, there have been growing concerns over emerging contaminants from a group of manmade chemicals known of per- and poly-fluorinated alkyl substances (PFAS). These compounds were often used in fire-fighting foam and a wide variety of commercial and industrial applications. PFAS are persistent and resist degradation in the environment. An increase in [...]
