2 understanding microbial Biofilms in Receiving Waters Impacted by airport Deicing activities • Reduction in biofilm growth has been observed with reduced deicer concentrations at some airports. • To date, only one airport has been able to successfully reduce biofilm proliferation to acceptable levels, according to the requirements of that airport's National Pollutant Dis charge Elimination System (NPDES)

4 understanding microbial Biofilms in Receiving Waters Impacted by airport Deicing activities the carbontonitrogen ratio is about 57; substantially greater than the generally accepted Redfield Ratio of about 6.6:1. This observation suggests that biofilm is capable of maintain ing a steadystate biomass with less N than that which would be generally expected.

Field Investigations Research is needed that documents the change in biofilm community diversity as organic carbon (C)

6 understanding microbial Biofilms in Receiving Waters Impacted by airport Deicing activities Modeling Tool Refinement and Application There are several suggested research activities related to the biofilm modeling tool. The model applied during this study simulated one profile of heterotrophic organism that is primarily responsible for the degradation of readily biodegradable organic material.
