Full Scale Coal Tar Remediation Related to Former Roofing Products Manufacturing

CONTAMINANT SUMMARY: Coal tar repurposed from a nearby Manufactured Gas Plant (MGP) for the roofing manufacturing process. MGP coal tar that was brought onto the site leaked into the subsurface, contaminating the soil and groundwater with benzene, toluene, ethylbenzene, and total xylenes (BTEX), naphthalene, and polycyclic aromatic hydrocarbons (PAHs).

CONTAMINANT SUMMARY: Manufactured gas was made primarily from coal, as well as many other organic feedstocks. During the gas manufacture, tars were created and leaked, spilled or discharged to the environment. These tars are not susceptible to natural degradation and are made up of 500 to 3000 different compounds. More dense than water, toxic coal tar tends to sink into the groundwater environment where they contaminate passing ground water.

Total Petroleum Hydrocarbons

CONTAMINANT SUMMARY: Total petroleum hydrocarbons (TPH) are a wide range of chemical compounds that are derived from crude oil. Crude oil is used to produce petroleum based products including diesel fuel, heating oil, and gasoline. Crude oil derived products can exist as immiscible compounds forming non aqueous phase liquids (NAPLs)  acting as long term sources of soil and groundwater contamination. TPH compounds can have detrimental health and environmental effects.  TPH contaminants are released to the environment from industrial, residential and private uses.  To eliminate these environmental hazards VeruTEK combines desorption and dissolution enhancement with a combination of our patented plant based surfactants, green catalysts and powerful oxidative/reductive compounds including sodium persulfate, hydrogen peroxide and green synthesized nanoscale zerovalent iron (GnZVI).

CONTAMINANT SUMMARY: Heating oil is a low viscosity, flammable liquid petroleum product used as a fuel for furnaces or boilers in buildings. Heating oil is commonly delivered by tank trucks to residential, commercial and municipal buildings and stored in above-ground storage tanks  located in the basements, garages, or outside adjacent to the building. It is sometimes stored in underground storage tanks. Leaks from tanks and piping are an environmental concern. Various federal and state regulations are in place regarding the proper transportation, storage and burning of heating oil, which is classified as a hazardous material (HazMat) by federal regulators.

Polychlorinated biphenyl (PCB)

CONTAMINANT SUMMARY: Polychlorinated biphenyls (PCB)
, a group of toxic chemicals once in widespread use, are insoluble and extremely resistant to natural decay. PCBs belong to a broad family of man-made organic chemicals known as chlorinated hydrocarbons. PCBs were domestically manufactured from 1929 until their manufacture was banned in 1979. They have a range of toxicity and vary in consistency from thin, light-colored liquids to yellow or black waxy solids. PCBs were used in hundreds of industrial and commercial applications including electrical, heat transfer, and hydraulic equipment; as plasticizers in paints, plastics, and rubber products; in pigments, dyes, and carbonless copy paper; and many other industrial applications.
