This powerpoint presentation begins by providing a brief overview of research motivation, understanding the mechanisms driving fate and transport of contaminants in distribution systems is critical for water security applications in order to: assess the public health and economic impacts of contamination incidents; improve detection methods; design contamination warning systems; decontaminate distribution systems; and, evaluate the performance of mitigation technologies. TEVA-SPOT Sensor Placement Software is presented, along with modeling arsenic oxidation/adsorption, and modeling E. coli. Presentation challenges include the following: contaminant fate and transport in drinking water - limited experimental data on disinfection reactions, adsorption/desorption rates, attachment to biofilms; complex ecosystem, natural organic matter, corrosion products on pipe walls, and various pipe materials throughout the system. Includes figures.
