Contaminated Sediments CAN Be CleanedContaminated Sediments CAN Be Cleaned
Sediments are highly complex mixtures of organic and inorganic material
Experiments show that chemical and mechanical means can clean organic and inorganic contaminants
BioGenesissm chemicals and full–scale equipment implement experimental findings in a practical way
