ABSTRACT:
A method for removing heavy metals and halogenated hydrocarbons from contaminated groundwaters is provided. The method provides utilizing a treatment solution comprising a soluble source of organic carbon, ferrous iron, and sulfate. Additionally, the treatment solution may comprise sulfate reducing bacteria as well as nutrients for bacterial metabolism. The treatment is designed to stimulate the growth of naturally occurring sulfate reducing bacteria such that the metals are coprecipitated in iron sulfide and the hydrocarbons are reduced to innocuous byproducts.
