XI. Screening Values/Recommended Actions:

Sampling results will be evaluated by individual residence and by building. Each contaminant level will be compared with its screening values (tables that follow). Actions associated with screening values include: no further action, clean the area, and clean and resample the area. I Recommendations for sensitive members of the population are also included. If a screening value is exceeded, sample collection and questionnaire information will be reviewed to determine if the levels could be due to other sources (e.g., cigarette smoke, nearby construction). If other sources are plausible, recommendations will still be made, but qualified.
