Fenton’s Reagent
Fenton’s Reagent has been widely use to degrade a host of chlorinated and non-chlorinated contaminants including petroleum (diesel, gas), chlorinated hydrocarbons (PCE, TCE, etc), PNA’s, pesticides, and others. Traditional Fenton’s Reagent utilize a transitional metal catalyst to form a hydroxyl radical. The short lived hydroxyl radical is very effective in mineralizing contaminants. No by-products of concern are formed when using Fenton’s Reagent. Fenton’s Reagent is typically applied in either a in-situ application (chemical injection) or through ex-situ (physical mixing) the chemistry in soils, groundwater, and wastes.

Modified Fenton’s Reagent
A modified Fenton’s Reagent is similar to a traditional Fenton’s Reagent except a different catalyst is used. Alternate catalysts include proprietary organic acids and cheated metals.

Persulfate
Persulfate forms a sulfate radical when activated. The sulfate radical is a very strong oxidizer capable of mineralizing a wide array of organic contaminants including (PCE, TCE, etc), PNA’s, pesticides, petroleum and others. Persulfate can be activated to form the sulfate radical by a number of methods including transitional metals, heat, and other oxidants. Persulfate activation produces sulfate ions as a by-product, which may impart a salty taste in groundwater. Persulfates can be applied in-situ and ex-situ to treat soil, groundwater and other wastes.

Permanganate
Permanganate is very effective in mineralizing chlorinated hydrocarbons in soils, groundwater and wastes. Permanganate does not require a catalyst or activations and can be applied over a wide pH range. Reaction by-products of permanganate include manganese dioxide. Permanganate is generally applied in-situ to treat contaminated groundwater and soil.

Other Chemistries
Various combinations of treatment chemistries can be applied depending on the material treated, contaminant levels and combination of contaminants.
