A method for remediating aquifers and groundwater contaminated, for example, by toxic halogenated organic compounds, certain inorganic compounds, and oxidized heavy metals and radionuclides, using the introduction of an innocuous oil, preferably an edible, food grade oil such as soybean oil, formulated into a microemulsion preferably by mixing with a natural food-grade emulsifier (such as lecithin) and water.

1. A method for remediating a selected aquifer in a sediment having a mean pore size to reduce contaminants in the aquifer, comprising:a) evaluating the aquifer for contaminant identity and location, b) determining whether aquifer pretreatment should be done, and if so, pretreating the aquifer, c) treating the aquifer with a selected amount of an oil microemulsion having an average droplet size less than the mean pore size of the sediment, d) determining whether aquifer post-treatment should be done, and if so, post-treating the aquifer; and e) monitoring the aquifer to determine if remediation has been accomplished.
