    In 1982, the Marine Corps discovered volatile organic compounds (VOCs) in several drinking water wells that fed into two of the eight water systems. The sources were traced to tetrachloroethylene (PCE) from a two dry cleaners – one on base, the other off the base and trichloroethylene which had been used in vehicle maintenance on the base ...

    The VOC Solvents Emissions Directive was the main policy instrument for the reduction of industrial emissions of volatile organic compounds (VOCs) in the European Union. It covers a wide range of solvent-using activities, e.g. printing, surface cleaning, vehicle coating, dry cleaning and manufacture of footwear and pharmaceutical products.

    Some subset of DOC constitutes the precursors of disinfection byproducts for drinking water. [15] BDOC can contribute to undesirable biological regrowth within water distribution systems. [16] The dissolved fraction of total organic carbon (TOC) is an operational classification. Many researchers use the term "dissolved" for compounds that pass ...
