Chloraminated Drinking Water Distribution System Simulator

Many US water treatment facilities use chloramination to control disinfectant by-product formation. Chloraminated drinking water distribution systems (DWDS) are engineered environments that are subject to frequent and variable disturbances. While biofilms are ubiquitous in DWDS and difficult to control, very little is understood about temporal changes in their bacterial populations, particularly when subjected to nitrification and chlorine burn treatments. Therefore, it is important to understand the ecology of these environments to better assess potential risks and ultimately to develop guidance for optimization of nitrification control strategies. For this project we have data from three different sources: 1) 16S-tag data (DNA from environment) 2) whole shotgun metagenome (DNA from environment) 3) whole genome (DNA from isolates). Pure cultures isolated from biofilm or bulk water (i.e. inoculum) under different operational conditions
