Development of Field Site To Support Implementation and Testing of Early Warning System
Project Title: Development of Field Site To Support Implementation and Testing of Early Warning System
The objectives of this collaborative effort between the EPA/NHSRC, and the USGS are to lay the ground work for developing an EWS field site at an operating water utility by designing and deploying an array of water quality sensors to characterize baseline water quality variability within the distribution system.
Statement of Problem
Distribution system EWS would, in the most optimal case, detect contamination events quickly and with very low rates of false positive and negative reports. Work on such systems is just be-ginning, but one early-proposed approach involves on-line sensors coupled with simple statistical measures of signal excursions from an expected (or baseline) value.
Strategy and Approach
The research tasks outlined are intended to produce a useful collaboration with at least one water utility, for purposes of acquiring a water quality data set to determine baseline water quality variability. Work during this study will baseline the water quality variability for at least one water utility and thereby lay the groundwork for an EWS field study site, including a full understand-ing of system operation and hydraulic/water quality behavior, field installation of a sensor array and possible connection to the existing data acquisition system. In addition to valuable field data collected during the study period, the outfitted distribution system and utility collaboration will serve as a useful test bed for future testing and evaluation of an integrated Early Warning System.
