Contamination Warning Systems are key in protecting a City's drinking water. NYCDEP sought the services of CH2M HILL & Malcolm Pirnie along with Critigen to develop a CWS. The CWS protects the drinking water for New York and also provides real-time operational insight on the water quality.
The CWS utilizes real-time component data to provide timely detection of contaminants:
Online Water Quality Monitoring - on-line sensors
Sampling and Analysis - laboratory results
Enhanced Security Monitoring - monitoring/surveillance of key facilities
Consumer Complaint Surveillance - monitoring customer calls for water quality issues
Public Health Surveillance - monitoring public health data for water related illnesses

Component data is analyzed/visualized through a web-based flex viewer application that provides fused views of data. This allows spatial correlation of events by end users. A SOA was utilized at both the component level and spatial level (ArcGIS Server), affording presentation of data in a real-time context.
