Fracking chemicals: Organic screening

David Bradley

Jul 15, 2015

thumbnail image: Fracking chemicals Organic screening

An organic screening framework has been used to identify organic components of hydraulic fracturing fluid that have potential groundwater risks associated with their use in the event of a spill. Of 659 different substances examined, researchers identified just 15 that could be problematic.

Infrared emissions of pentaerythritol tetranitrate deposited as contamination residues on various substrates were measured to generate models for its detection and discrimination from the emissions of the substrates.

The fluorescent properties of dissolved organic matter in fens and bogs in a Northern Minnesota peatland were studied using excitation-emission matrix fluorescence spectroscopy with parallel factor analysis, identifying four humic-like components and one protein-like component.
