Abstract: A method and system for forming an in situ subsurface filter in a contaminated aquifer and for removing contaminants from groundwater drawn from a contaminated aquifer. The filter is produced in situ by injecting an aqueous solution comprising bacteria-stimulating chemical components through a well to bioactively generate a subsurface mineral filtering zone surrounding the well. As water is subsequently drawn through the well, contaminants are removed from the water as it passes through the filtering zone.

Abstract: A systematic method of making donations to charities from investment income is provided. Mutual fund investors and other investors are provided with an option to designate that a gift to a charity is to be paid from the brokerage account. The gift may be of a fixed amount or of a percentage of investment income, or may be limited to a portion of investment income that is taxed at the highest tax rate for the investor. The mutual fund or investment management entity may receive compensation in the form of an administrative fee that may be a set annual amount or a percentage of gifts made.

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.

Abstract: Plant germplasm is transformed with foreign DNA by introducing the DNA into pollen grains by a technique such as electroporation, mating ova of the desired plant line with the transformed pollen, and selecting for the transformed germplasm. The germinating pollen, resultant seed, and the progeny can each be screened for expression of the foreign gene. The transformed pollen can be used as a vector for introducing the foreign DNA into plant lines of similar or dissimilar origin, including both monocots and dicots.
