EPA WSD Shares New Resource

Customer Complaint Surveillance (CCS) Resources:  Guidance and instructional videos for CCS are now available from EPA’s Water Security Division by clicking here.  “Designing Customer Complaint Surveillance for Water Quality Surveillance and Response Systems” provides guidance for designing a system to analyze customer complaints to detect water quality problems (e.g. taste, odor or appearance complaints).  The 48 page document contains several embedded forms, templates, and examples (to view these materials, you must first download the PDF version of document).  The “Instructional Videos on Customer Complaint Surveillance Tools” provide an overview and training on how to use two previously published tools, the Alarm Estimation Tool and the Threshold Analysis Tool.  Both are designed to help utilities analyze drinking water complaint data.  The videos range in viewing time from 5-9 minutes (total viewing time for all six videos is less than 40 min).
