Objective:
The investigators propose research that will link health outcomes, quantified through emergency department (ED) visits for gastrointestinal (GI) illness, to distribution system water quality and infrastructure characteristics. In addition, the investigators propose an integrative approach for characterizing health risks associated with microbial contamination of drinking water distribution systems through the development of vulnerability assessments and the implementation of an innovative continuous water quality monitor for use in distribution systems. The proposed study builds upon previous studies by the same investigators that examined the importance of distribution systems in providing safe drinking water. From these previous studies the investigators have access to extensive information regarding the drinking water distribution systems serving the Atlanta metropolitan area, which can be linked to ED data on GI illness in the community, allowing the assessment of potential health risks associated with drinking water distribution systems.
Approach:
The overall study design has three main parts. A pathogen contamination vulnerability assessment will be conducted for a selected drinking water utility. The investigators will extend, expand, and refine the epidemiological analyses involving distribution system exposure from their previous EPA-funded drinking water epidemiological study. The results from the vulnerability assessment will be leveraged by considering them as an exposure metric in epidemiological analyses. Concurrent with these aspects of the proposed study, the investigators will also directly assess distribution system water quality through an innovative continuous monitoring device.
Expected Results:
The intended outcome of the proposed research is improved public health protection through improved distribution system water quality, resulting from the knowledge gained from implementing vulnerability assessments and/or continuous monitoring and an understanding of the public health risks conveyed through contamination occurring in drinking water distribution systems. Further, the results of these analyses will inform the public health and drinking water communities regarding the usefulness of various measures of distribution system water quality. This information should be particularly useful as drinking water regulations are revised (e.g. Total Coliform Rule).
