ABSTRACT
One of the main difficulties in epidemiological studies which examine the relationship between drinking water contaminants, and disease outcomes, is the accurate assessment of individuals’ consumption of tap water (Shimokura et al. 1998). A recent workshop identified improving methods for measuring water consumption patterns as a primary research need for epidemiological studies (Arbuckle et al. 2002). Although this workshop was primarily concerned with the health risk associated with disinfection by-products in domestic water, their conclusions are relevant to the study of other drinking water contaminants.
