• <br /> Geographic Information Systems, ArcView Application The University of Oregon, Community Planning <br /> Workshop, developed an ArcView application for the storm event data. The application provides numerous <br /> tools for linking the water quality database and spreadsheet files to map coverages, as well as querying files, <br /> generating charts, graphs, and reports. <br /> Clean Sampling Techniques In 1995 the City initiated a study to evaluate the impact of using "clean <br /> techniques" for the collection and analysis of ambient samples of the Willamette River. Samples were <br /> collected by City staff using special techniques designed to prevent sample contamination. Samples were <br /> then shipped to a contract laboratory where analyses were performed in special areas known as "clean <br /> rooms." The analytical method used at the contract laboratory significantly reduces the detection level. The <br /> time required to collect samples and the costs of analyses using clean techniques are significantly higher <br /> when compared to standard procedures. <br /> The results of the clean techniques study are still under evaluation. It is clear from the data collected thus <br /> far that the results of this study will affect future stormwater and ambient data collection efforts. <br /> Future Activities <br /> Storm Event and Ambient Data The City is now evaluating software for more detailed analysis of the data. <br /> A statistical trend analysis module will be purchased in permit year two, and staff will continue to evaluate <br /> stormwater analytical tools as they become available. <br /> Geographic Information Systems, ArcView Application Software necessary to use the application <br /> developed during permit year one is available only on a few workstations. During permit year two, the <br /> application will continue to be enhanced and made available to additional users. Future enhancements <br /> include the addition of ambient receiving water monitoring stations and their associated data. The location <br /> of industrial facilities will also be added to the database to allow the user to correlate the location of <br /> industries to the land use and ambient receiving water monitoring stations. <br /> Clean Sampling Techniques During the second permit year, selected aspects of the clean sampling program <br /> will be applied to the storm event and ambient monitoring programs. Sample results using these modified <br /> techniques will be compared to samples collected using standard collection methods. <br /> Laboratory System The City of Eugene is currently accepting proposals for a Laboratory Information <br /> Management System (LIMS). The LIMS will allow data to be collected, transmitted, and stored in a central <br /> database. The development and implementation of the LIMS should benefit the management of the <br /> stormwater and ambient data. <br /> 11 <br />
