Contaminants Tested

The following contaminants were tested:

  • Petroleum hydrocarbons
  • Metals (e.g lead and cadmium)
  • Volatile Organic Compounds (solvents historically used in maintenance/cleaning)
  • Semi Volatile Organic Compounds (compounds found in petroleum products)
  • Pesticides/herbicides
  • Polychlorinated Biphenyls (coolants historically used in electrical equipment)

Contaminant Category Historical Sources

  • Total Petroleum Hydrocarbons (TPH): Diesel fuel, gasoline, engine oil, grease
  • Metals: Batteries, truing (grinding) for train wheel and track maintenance, treated wood (rail ties)
  • Volatile Organic Compounds (VOCs): Solvents, degreasers, painting products (resins, sealants, solvents, lacquers, varnish)
  • Semi-volatile Organic Compounds (SVOCs): Paint strippers, resins, adhesives, degreasers
  • Pesticides/Herbicides:Landscape maintenance and pest management
  • Polychlorinated Biphenyls (PCBs): Coolants and lubricants in transformers, capacitors and other electrical equipment. Also found in fluorescent light fixtures and hydraulic oils.
