this report, frequencies and durations of use of showers, baths, clothes
washers, dishwashers, toilets and faucets are presented and compared for
various demographic groups derived from analyses of the National Human
Activities Pattern Survey (NHAPS) database, the Residential End Uses of
Water Study (REUWS) database, the Residential Energy Consumption Survey (RECS),
as well as from current literature and manufacturer information. Volumes and
flowrates are also analyzed from REUWS for the various water uses.
Furthermore, tap water ingestion data are analyzed for various population
groups derived from the Continuing Survey of Food Intake by Individuals (CSFII)
as well as from NHAPS and current literature. Typical parameters of indoor
water-uses are presented and recommended for use in human exposure modeling.
