1. A method of in situ remediation of contaminated media, comprising:
introducing into the contaminated media an aqueous suspension of a bioremediation composition,
wherein the bioremediation composition comprises:
a first bioremediation composition comprising a first blend of one or more organisms capable of degrading hydrocarbons;
a second bioremediation composition comprising a second blend of one or more organisms differing from the first blend of one or more organisms and being capable of degrading at least one halogenated compound;
an organic compound comprising a polysaccharide, the polysaccharide excluding cold water soluble starches; and
a third blend of one or more organisms capable of degrading the organic compound, and
wherein the first bioremediation composition further comprises an adsorbent capable of adsorbing hydrocarbons and a compound that releases sulfate over a period of time and wherein the first blend of one or more organisms comprises a nutrient system for promoting growth of microorganisms capable of metabolizing the hydrocarbons.
