“…Thus, because of these extrapolations, dose response models are uncertain. Besides the physiological component, human behavioral characteristics, such as ingestion rate of tap water, also add uncertainty and variability in the risk related parameters [ Burmaster and Wilson , 1996; Maxwell et al , 1998; Daniels et al , 2000].…”

[1] Defining rational and effective hydrogeological data acquisition strategies is of crucial importance as such efforts are always resource limited. Usually, strategies are developed with the goal of reducing uncertainty, but less often they are developed in the context of their impacts on uncertainty. This paper presents an approach for determining site characterization needs on the basis of human health risk. The main challenge is in striking a balance between reduction in uncertainty in hydrogeological, behavioral, and physiological parameters. Striking this balance can provide clear guidance on setting priorities for data acquisition and for better estimating adverse health effects in humans. This paper addresses this challenge through theoretical developments and numerical simulation. A wide range of factors that affect site characterization needs are investigated, including the dimensions of the contaminant plume and additional length scales that characterize the transport problem, as well as the model of human health risk. The concept of comparative information yield curves is used for investigating the relative impact of hydrogeological and physiological parameters in risk. Results show that characterization needs are dependent on the ratios between flow and transport scales within a risk-driven approach. Additionally, the results indicate that human health risk becomes less sensitive to hydrogeological measurements for large plumes. This indicates that under near-ergodic conditions, uncertainty reduction in human health risk may benefit from better understanding of the physiological component as opposed to a more detailed hydrogeological characterization.

“…In 2002, a Groundwater Quality Protection guide provided a detailed description of the evaluation process of groundwater vulnerability and risk and was published by the World Bank (Foster et al 2002). Taking uncertainty into consideration, Daniels et al (2000) used the cumulative distribution function to reflect the uncertainty and change of parameters and obtained a proper estimation for events of trichloroethylene groundwater contamination at Beale Air Force Base in California, USA.…”

“…The most likely exposure scenarios can be defined based on climate and terrain. Within such exposure scenarios, exposure and dose parameters can be assessed probabilistically using Monte Carlo analyses (see Daniels et al, 1993 [14] and 2000 [15] and also Daniels and Tompson, 2003 [1]). It is factually incorrect to assume that only the SDWA NPDWRs for radionuclides would be applicable as the only strategy for decision making, even though they are the only enforceable standards.…”
