Contaminants Treated with Recirculating Wells

A wide variety of contaminants can be treated with the six recirculating well technologies we use. Volatile organic contaminants, such as solvents and gasoline. Semi-volatile contaminants, such as MTBE and some diesel constituents. Inorganic contaminants, such as chromium and arsenic. Floating substances (LNAPLs), such as gasoline and lubricating oils.

A contaminant can be removed from groundwater with one of our technologies if:

It is volatile or semi-volatile,
It can be treated with granular activated carbon,
It can be treated with an ion exchange resin or other exchange medium,
There is an adsorptive or reactive medium for treating it as a water contaminant, or
It is aerobically or anaerobically biodegradable.

The entire range of contaminants exemplified below can be treated with our patented and patent-pending recirculating well technologies, without pumping the water to the surface and with no aboveground treatment.

Example contaminants that can be removed:

Chlorinated Hydrocarbons:

TCE, PCE, DCE, DCA, chlorobenzene, dichlorobenzene, chloromethane, chloroethane, carbon tetrachloride, chloroform, methylene chloride, 1,1,1-trichloroethane, vinyl chloride

Fuel Spills:

Gasoline, diesel, Jet A, other fuels, benzene, ethyl benzene, toluene, xylenes, methyl-tert-butyl ether (MTBE), tertiary-butyl alcohol (TBA)

LNAPLs:

Lubricating oils, cutting oils, food-grade oils, LNAPL components of crude oil, paint solvents, non-polar solvents, gasoline, diesel, Jet A

FGMP Contamination (Coal Tar):

Benzene, ethylbenzene, toluene, xylenes, naphthalene

Other Volatile and Semi-Volatile Organic Contaminants:

Methyl-ethyl ketone, creosote

Other Organics:

Some explosives, some pesticides, PCB

Metals:

Lead, chromium, uranium and other radioactive species, mercury, cadmium, copper, nickel

Inorganic Contaminants:

Nitrates, sulfates, perchlorates, arsenic
