How do microbial products compare economically?
Biological treatment with these products is far less costly than mechanical dredging, incineration or paying fines. Chemical treatments may be less expensive, when measured by the pound or gallon, but are stop-gap remedies and generally address only one aspect of contamination. Microbial products give greater value for the dollar spent because they treat the whole system. Natural systems regain their own capacity for self purification.
