Henry Schuver, US EPA, OSWER-OSW
20th Annual Int. Conf. on Soils, Sediments and Water

2. Non-Residential Buildings
Not in VI Guidance screening values
Not in Q4 Generic screening values
Not in Q5 (Fig. 3) screening values
Can be Q6 site-specific model [w/ sampling]
(of USEPA’s (OSWER) Nov Draft VI Guidance)

3. Scope of the Guidance (Sec. 1D)
Intent:
“incremental increases in exposures”

4. Scope of the Guidance (Cont.)
Recommended adjustments:
Air Volume (of buildings)
Air Exchange Rates (fresh air)
Exposure Durations (yrs, d/y)
(h/d [IR, tox., controls?])
Can use CERCLA spreadsheets to modify these:
