This reserch used molecular methods to investigate the presence of bacterial and archaeal microorganisms not previously reported as being present in distribution systems to determine if there is a "normal microflora." The project designed a comprehensive 16S-based microarray for a systematic analysis of bacterial and archaeal communities and evaluated if the composition of the communities is affected by variables such as water age, pipe materials, and disinfectant concentration. The research also performed quantitative analyses of selected microbial groups to confirm and quantify their presence in distribution systems. Published in 2013.
