The Environmental Public Health Tracking (EPHT) Program is the first national effort to create a network to provide the United States with standardized data integrated from multiple hazard, exposure, and health effects information systems. Limited Department of Environmental Quality (DEQ) Air Quality Monitoring Data from the Laboratory Analytical Storage and Retrieval Database (LASAR) are available on the Oregon EPHT website at http://www.oregon.gov/DHS/ph/epht. The Oregon EPHT Air Quality Monitoring dataset contains information about PM2.5 and PM10 levels. The data are from filter and light backscatter monitors. Analyte mean and maximum measurements, and count and percentages of violations of Maximum Contaminant Levels (MCLs) are available from 1997, for the state and by county. Data from the EPHT network may be used to attempt to quantify the magnitude of environmental health problems, detect unusual trends and occurrences, document the distribution and spread of a hazard or health event, identify populations at risk, plan and evaluate protective and preventive measures, facilitate research, and detect the results of changes in health practices. The Oregon EPHT Program is part of a National EPHT Network sponsored by the CDC. The Oregon EPHT Program resides in the Toxicology, Assessment, and Tracking Section of the Office of Environmental Public Heath (OEPH) which is in the Public Health Division of the Department of Human Services (DHS).

The purpose of the Oregon EPHT Program is to provide scientific information from a web-based network of hazard, exposure, and health effect data to support actions that improve the health of communities. By bringing together, and standardizing, local, state, and national data sources of environmental and health information, scientists, policymakers, and the public will be able to more effectively address fundamental questions about relationships between environmental exposures and health effects.
The LASAR database was created and is maintained at the Oregon DEQ Laboratory. The LASAR web access application was created and is maintained by Oregon DEQ Managment Services Division. The goal of the LASAR Database is to make environmental data collected by DEQ for program needs, or submitted to DEQ under agreement for contractual obligations, or as volunteered for consideration in policymaking, available to the public.
All data are entered into the Laboratory Information Management System (LIMS). Data verification and validation is performed in LIMS prior to release of the data to the Laboratory Analytical Storage And Retrieval (LASAR) system. Qualtiy assurance/quality control (QA/QC) data, including replicate, blank, and spike samples, are maintained in a QA archive at the DEQ Laboratory. LIMS, LASAR, and the QA archive are maintained and operated by the DEQ Laboratory Division. Data from LASAR (a transactional database ) are routinely transformed into a data warehouse maintained by DEQ Management Services Division and make available to the public via the LasarWeb application. Oregon EPHT aggregates the data available on the website by day, year, and county.
