Abstract: Bioremediation has been defined as a??the act of adding materials to contaminated environments to cause an acceleration of the natural biodegradation processesa??(Swannell et al., 1996; U.S. Congress Office, 1991). Results from a laboratory study and a field trial investigation showed that the biodegradation loss of aliphatic i.e. straight (i.e. C10-C33) and branched (i.e. pristane and phytane) alkanes in sediments amended with a slow release fertilizer, i.e. Osmocote was approximately 1.88-fold (over a 30-day period in a laboratory study) and 1.5-fold (at 28-day period in a field trial investigation) higher than an unamended control sediment. A laboratory study also showed that the biodegradation and leaching losses of aliphatic and polycyclic aromatic hydrocarbons (i.e. 4-ring and 5-ring) in sediments amended with a surfactant i.e. Tergitol NP-9 were approximately 37% higher than an unamended control sediment over a 49-day period. Tergitol NP-9 slightly increased the bioavailability of hydrocarbons (i.e. aliphatic and PAHs) to the microbial biomass and enhanced the hydrocarbon water solubility.
