Impact/Purpose:
The metagenomic approaches used in these studies will help to develop a more comprehensive understanding of the microbial ecology of drinking water distribution systems relative to what disinfectants are used. Such information is critical to the design of effective management practices, and will ultimately help prevent waterborne disease and safeguard human health.
Description:
The purpose of this research was to add to our knowledge of chlorine and monochloramine disinfectants, with regards to effects on the microbial communities in distribution systems. A whole metagenome-based approach using sophisticated molecular tools (e.g., next generation sequencing) was used to assess the microbial composition and the metabolic potential in these communities. In addition, this research produced insights on the importance of certain operational parameters in biofilm-related research.
