The purpose of the project was the development of a funnel and gate system for PAH-contaminated groundwater
at a former manufactured gas plant. Different types of activated carbon as potential gate materials were tested
for adsorption capacity and long term stability. However, the application was facing clogging by microbial growth
on the adsorptive material. To circumvent this problem, research was performed to identify the cause for biomass
accumulation. Investigations were focusing on parameters responsible for enhanced microbial growth in the
groundwater. Nutrient levels, pH, redox potential, and possible substrates were measured in addition to aerobic
and anaerobic colony forming units.
