Water Security

Appears in the issue.

GuardianBlue is an early warning monitoring system designed to help cities protect their drinking water systems from terrorist contamination attacks and other threats. Developed by the Hach Company of Loveland, Colorado, the system has received SAFETY Act Designation and Certification from the U.S. Department of Homeland Security. It uses patented event monitor technology to detect, alert, and classify contaminants, including cyanide, pesticides, Ricin, and VX. The system can alert operators to threat agents, contamination, and operational issues before they spread or impact the entire water system. It integrates multiple sensor outputs from the Water Panel and TOC Analyzer. Every 60 seconds, it applies an algorithm to the sensor measurements, calculating a site’s water quality baseline, and alarms when the trigger signal exceeds a user-set threshold.
