WARNING! DATA USE RESTRICTIONS
Read Carefully Before Using
The EPA does all it can to ensure that the identity of survey participants cannot be disclosed. All direct identifiers, as well as any characteristics that might lead to identifications, are omitted from the data. Any intentional identification or disclosure of a person or establishment violates the assurances of confidentiality given to the providers of the information. Therefore, users will (1) use the data in this study for statistical reporting and analysis only; (2) make no use of the identity of any person or establishment discovered inadvertently and will advise the HEDS Administrator of any such discovery; (3) will not link this data with individually identifiable data from other EPA or non-EPA data.
By using the data you signify your agreement to comply with the above-stated statutorily based requirements.

Description:
This abstract is included for completeness of documentation. The technique described in the SOP title was planned in writing the QSIP. It was subsequently not used, and the SOP was not written.
The National Human Exposure Assessment Survey (NHEXAS) is a federal interagency research effort coordinated by the Environmental Protection Agency (EPA), Office of Research and Development (ORD). Phase I consists of demonstration/scoping studies using probability-based sampling designs. The studies collected household environmental and personal samples for chemical analysis, and questionnaires were administered. The NHEXAS Phase I Questionnaires were organized into six modules for simplicity in administration (to minimize respondent burden and maximize participation rates at each step) and for collecting information that can be temporally related to the exposure, concentration, and/or biological measurements collected in NHEXAS: Descriptive, Baseline, Technician, Follow-up, Time and activity diary, and Dietary diary (and follow-up). The NHEXAS Arizona study sampled residences determined by a population-based probability research design for the total population of Arizona and measured metals, pesticides, and volatile organic compounds (VOCs). Analytical results were obtained under strict QA/QC requirements during collection, processing, and final deposition into databases. In addition, strict standard operating procedures were followed throughout the NHEXAS Arizona study. The study was conducted by a consortium composed of the University of Arizona, Battelle Columbus, and the Illinois Institute of Technology. Data collection occurred between June 1995 and February 1998 for the participating households.
