Newman Zone Formulations
Standard FormulationAll Newman Zone® formulations contain 46% soybean oil by weight (50% oil by volume), 4% sodium lactate, and emulsification additives and preservatives. The standard formulation is the original product first manufactured in February of 2002. It contains both ionic (lecithin) and nonionic surfactants to produce a very stable emulsion that can be retained even on clean sand soils.
Nonionic Formulation
The first full scale production run of Newman Zone® Nonionic emulsion was completed in November of 2004. Ionic surfactants such as lecithin can adsorb very strongly to clays and silts which may make distribution of an emulsion through them difficult with ionic surfactant blends. The nonionic emulsion has very low adsorption for injection into low permeability silts and clay soils.
Buffered Nonionic Formulation
Optimal pH for reductive dechlorination usually falls in the range of 6.5 to 8.5; dechlorination can be severely retarded at pH values below 6. Injection of an electron donor at sites with little natural buffering capacity commonly results in a drop in pH, sometimes as low as a pH of 5 or less. The buffered nonionic formulation contains 1% sodium bicarbonate to help maintain pH within the 6.5 to 8.5 range.
