EPA evaluated approaches to warning systems that integrate information from a variety of sources, including: Water Security Modeling and Simulation Research One major challenge in the use of sensors to monitor water quality is how to distinguish between normal fluctuations in water quality and changes due to contamination or operational problems.
It can automatically review incoming data, detect unusual conditions, and send alerts for the water utility to take further action. CANARY can detect unusual conditions resulting from contamination incidents, as well as detecting unexpected, but normal operating upsets, such as a sensor malfunction or a pipe break.
Open source means that the original source code for the software is made freely available for distribution and for others to modify. EPANET-RTX provides the methods and software tools by which operational data can be connected with a network infrastructure model, and the resulting network simulation model can be calibrated, verified, and continually tested for accuracy using operational data.
Analytics refer to the discovery and interpretation of patterns in data. LINK can provide a web browser i. LINK can provide a real-time, web browser-based view of hydraulic and operational assets e. Additionally, real-time analytics offers water utilities the ability to more accurately identify when contamination has entered the water system, where it entered the system, and, most importantly, the valuable information to enable timely and effective response.
Public health surveillance includes monitoring poison centers and emergency calls, over—the—counter medication sales, and the number of patients reporting certain symptoms to doctors. Increases in any of these indicators could signal a disease outbreak.
Integration of this information with water quality data could indicate whether water contamination was the source of the outbreak. EPA researchers have been working to integrate an established public health surveillance system, the Electronic Surveillance System for the Early Notification of Community—based Epidemics ESSENCEwith water quality data to improve the effectiveness of contamination warnings systems.
The ultrafiltration device can concentrate the microorganisms contained in a gallon water sample into less than two cups of water in about an hour. Concentrated samples allow for more accurate detection of low levels of microbes in water samples.He has published extensively on hydrological extremes, climate change, and hydrological processes from catchment to global scale, and on the application of fundamental research to natural hazards impacts reduction, and water and food security particularly in developing regions, including monitoring and prediction systems.
Global Food Security Key Judgments Bottom Line: We judge that the overall risk of food insecuritya in many countries of strategic importance to the United States will increase during the next 10 years because of production, transport, and market disruptions to local food availability, lower purchasing power, and counterproductive government policies.
EPA has collaborated with the American Water Works Association (AWWA) to develop contingency plans in the event of a large-scale disaster.
Planning for an Emergency Drinking Water Supply has recommendations on planning for alternative drinking water sources and water . Free Essay: Using named examples, assess the contribution of large scale water management projects in increasing water security.
