The New York City Department of Environmental Protection (DEP) deployed in the 1990's an asset management and customer service database. Tracking of water quality-related calls began in 1999. The number of calls and spatial analysis of the number of calls received for water quality-related calls demonstrate that consumers do call as a result of sudden water quality changes. The analysis of consumer calls can play an important role in identifying intentional contamination of a water supply. It should complement data gathered from other sources that include real-time on-line sensors, syndromic surveillance, and be used with mapping used for distribution system models and consequence analysis. The present analysis uses community districts which are political boundaries used for city service delivery. Efforts are underway to map calls by pressure zones and automate the mapping of calls in real-time. Includes tables, figures.
