The National Water Quality Monitoring System plan was set to achieve two goals: 1) to raise the public’s rate of use of water information services, and 2) to enhance data analysis in order to better guide water related policy decisions in accordance with this plan. Outcomes from this plan are specified below: 1. In order to raise the public’s rate of use of water information services, there were three aspects: (1) A conversion of the water quality annual report from a paper version to a web based electronic version has been completed. This electronic version features 71 table listings plus 175 diagrams of water quality data from four categories of water bodies: rivers and streams, reservoirs, groundwater, and recreational coast areas. Through a series of efforts in scope setting, programming, web design, and well-managed time control, this electronic version raises not only the efficiency of editing the water quality annual report, it also enlarges the potential audience and reduces the use of printing paper. (2) Studies were conducted through analyzing reports from 41 international and domestic research papers on water quality monitoring data. A summary was compiled with respect to statistical analysis, water quality indicators, and water quality analysis models. This summary, which covers various techniques, can broaden our vision and serve as a useful reference to the public. (3) Incorporate Canada’s CCME principles of water quality monitoring for TEPA’s future reference. 2. In order to enhance the public sector’s water related policy decisions, data analysis was emphasized together with more tools incorporated into the system. This can be described in three categories: (1) We use SAS 9.0 and added tools like Web OLAP Viewer, Web Report Studio, Office Add-In 3 to produce interactive reports. These tools offer Drill Down, Drill Up analysis and multiple angle transformation analysis. These functions enhance the ability to interpret data hence can contribute to better decision making. (2) Compile and maintain the Water Quality Exchange Standard (WQX) and its web-service interface. Integrate water quality data from 25 outside sources, including 24 EPB and Water Resources Agency, Ministry of Economic Affairs. (3) Add Google Maps and ESRI ArcIMS into the system. The geographic presentation of water monitoring spots and water quality data allows users to view a comprehensive spatial depiction of analysis results. It helps to communicate the essential environmental significance of quantitative water quality data.
