This paper is summarized from a report prepared by the Houston Regional Monitoring Corporation for submission to the U.S. Environmental Protection Agency explaining the methodology used in the East Harris County and West Chambers County for assessing community exposure to volatile compounds. The paper briefly discusses the program description, the rationale for selecting candidate airborne chemicals for detailed health effects assessments, and the method used to develop consensus guidance values based on accepted risk assessment methodologies. The results of a 6-month monitoring period are presented with health assessment indicators.
