A systematic exposure assessment process has been developed for evaluating and describing the distribution, within large populations, of human exposures through drinking water to substances of potential health concern.
This process involves dividing the population into groups of known size, within which the drinking water exposure is the same or similar, and estimating the exposure concentration for each group based on the best available data.
Using this process, assessments of human exposures to atrazine though drinking water have been carried out for the populations of the states of Ohio, Illinois, and Iowa.
The assessments indicate that atrazine exposure through drinking water does not represent a significant human health threat based on the current understanding of atrazine toxicity.
Exposures to atrazine above the lifetime health advisory level of 3.0 ppb do not exceed 0.25% of the assessed population in any of the three states, and between 94% and 99% of the assessed populations have exposure concentrations less than 1 ppb.
