Description
Several toxicological and epidemiological studies have established a relationshipbetween disinfection byproducts (DBPs) in tap water and human health outcomesincluding cancer and adverse reproductive outcomes. DBP exposure is multi-route andits degree will vary according to individuals’ water use habits and location of consumers’taps within the distribution system. Because DBPs can be ingested from a variety ofsources including directly as tap water, from filtered water and bottled water, or inprepared beverages and food, a more thorough investigation of home filtration systems,bottled water, and water preparation is necessary for more accurate exposure assignment.This study examined bottled water brands consumed and filtration systems employed bya cohort of women enrolled in a study linking tap water and reproductive outcomes. Fourdifferent filtration units were evaluated in a home serviced by the same municipal wateras the cohort. Each filter removed greater than 80% of trihalomethanes (THMs) at alltimes when used according to manufacturers’ direction. However, some filters onlyremoved between 30 and 60% of total organic halides (TOX) and haloacetic acids(HAAs). The HAAs and THMs consumed from filtered water can account for 50% of aconsumer’s exposure through the ingestion pathway. Includes 20 references, tables, figures.
