Abstract
A method for the in-situ biological remediation of groundwater contaminated with halogenated organic compounds, heavy metals, various inorganic compounds, nitrate, and other compounds which can be reduced into less harmful by-products under anaerobic conditions through the application and distribution of a water-soluble microbial substrate mixture consisting of alcohol, carboxylates, and glycerol in an alkaline solution. The method delivers and distributes a substrate mixture into impacted groundwater zones using different mixture proportions based on aquifer conditions so as to optimize distribution in the aquifer. Acclimated microbes and nutrients are also added as needed.
