Project Highlights

Water quality models are widely used in analyses of water distribution systems. These network models have been used quite successfully for operational purposes, but in the context of providing real-time response for contamination events, the general mixing assumptions are most likely inadequate. Water security has been a concern of the water distribution community for several years, and it has become apparent that additional accuracy is critical to properly develop real-time response tools, especially if in-situ sensor equipment will be used to help detect intrusions. Current models assume instantaneous and complete mixing at pipe junctions and several studies have contributed to growing evidence that this assumption may be inadequate. The 'complete' mixing assumption becomes especially questionable at pipe cross junctions, where there may be limited contact and retention time between the water flows in two incoming pipe legs. The impact of solute mixing at these intersections, geometric components of a network system, is the focus of this work. Our computational and experimental results clearly indicate that mixing at pipe cross junctions is far from 'perfect'. Incomplete mixing results from bifurcating inlet flows that reflect off one another with minimal contact time. Improving the existing water quality model based on accurate mixing data and simulations is important not only to predict concentrations of chemical species such as chlorine in water distribution systems, but also to prepare for potential intentional and accidental contamination events.

CAMRA Activities
Date: Aug 19 - 24
This week long institute was held on the Michigan State University campus. The institute aimed to teach participants tools and skills to quantitatively asess microbial risk to human health in various situations in the indoor and outdoor environment. Participants learnt how to use risk assessment for assuring safety and health goals, using scientific data and computer analysis.

3rd Quantitative Microbial Risk Assessment Summer Institute
August 10 -15, 2008 Michigan State University
This week long Quantitative Microbial Risk Assessment Summer Institute (QMRA SI) held on the Michigan State University campus aims to teach participants tools and skills to quantitatively assess microbial risk to human health in various situations in the indoor and outdoor environment. Participants will learn how to use scientific data and computer programs towards building a risk assessment for assuring safety and health goals. Designed for graduate students and professionals in fields such as engineering, microbiology, epidemiology, medicine, public health, nursing, veterinary medicine and emergency preparedness. Students will gain hands-on experience with risk assessment software and work on real-world case studies.
Registration:
*Class is full for this summer. You may contact Lorie at neuman@msu.edu to be put on the waiting list or get on the mailing list for next year.

Fellowship Program in Microbial Risk Assessment for Public Security, Safety and Health
With support from the Department of Homeland Security, Drexel and Michigan State Universities are offering a fellowship program in Microbial Risk Assessment for Public Security, Safety, and Health.
The fellowship program will integrate:
• Academic coursework resulting in a Master’s degree with a graduate certificate in Microbial Risk Assessment
• Research at the Center for Advancing Microbial Risk Assessment, an Environmental Protection Agency and Department of Homeland Security Research Center of Excellence based at Michigan State University and Drexel University
• Two, 6-month professional internships at Homeland Security Science Technology Engineering Mathematics (HS-STEM) sites. Appropriate sites for completion of the internship include government agencies such as the Department of Homeland Security and Environmental Protection Agency, national laboratories, and university-based Department of Homeland Security Centers of Excellence.
Support
Support up to $2,300/month (tuition and stipend) is available for graduate students. Four Master’s Fellowships will be available at Michigan State University.
