ABSTRACT:
In a process of remediating chemical contamination of a pond contaminated with one or more toxic heavy metals or aromatic compounds, the steps include: preparing a silage of grass clippings, placing the silage on the surface of a pond, and inoculating the pond with an alga and Bacillus cereus in sufficient quantities to cause a mixed algal and bacterial bloom to form on the pond surface and become annealed to the silage, leaving the silage with the annealed bloom on the surface of the pond for a sufficient amount of time to allow the bloom to withdraw at least some of the toxic heavy metal content or to degrade at least some of the aromatic compound content of the pond, and removing the silage with the annealed bloom from the pond.
