“…Numerous studies have been performed to develop and to check of hybrid methods for specific aquifer vulnerability assessment based upon the parameters, using statistical criteria and weights based on the vulnerability models (Antonakos and Lambrakis, 2007;Baalousha, 2010;Bukowski et al, 2006;Capri et al, 2009;Draoui et al, 2008;Ghiglieri et al, 2009;Pacheco and Sanches Fernandes, 2013;Roelsma and Hendriks, 2014;Saidi et al, 2011;Sener and Davraz, 2013).…”

When used in a comprehensive risk assessment framework, aquifer vulnerability maps are a tool to identify the relative susceptibility of the groundwater from sources of contamination at the land surface. The DRASTIC method was designed for use over large areas with a wide variety of geological and hydrogeologic settings as a screening tool in groundwater protection and management. In this study, a series of vulnerability maps were made for the Greater Oliver area, in south central Okanagan, British Columbia, Canada, to test the sensitivity of the methodology to changes in input data type, interpretation, and mapping approaches. The study also illustrates how DRASTIC can be modified for use in areas of limited geological variability, where it may be important for smaller-scale changes in vulnerability to be recognized. Maps were produced using the original DRASTIC rating tables, a set of expanded tables using the original properties but modified ranges to accommodate the variability of data in the valley bottom region, and alternate tables, with modified properties and ranges. Differences in vulnerability rating for the maps using selected combinations and data interpretations are compared to the map using original DRASTIC rating tables using visual and statistical methods. One map was generated using expert hydrological knowledge. The modified tables allowed a greater amount of variability to be expressed in the valley bottom area compared to using the original tables and methods, and could provide a reasonable approach for assessing local scale variability for source water protection planning.

“…Others have shown that only a small number of parameters have the largest bearing on susceptibility. For example, Draoui et al (2008) found that parameters related to the soil and vadose zone most strongly affect susceptibility, while Nobre et al (2007) determined that susceptibility is most dependent on depth to water. It has been suggested that the complicated weighting and rating procedure is "self-defeating" (Holden et al 1992).…”

Assessing risk to groundwater quality using an integrated risk framework

2013

View full text Add to dashboard Cite

Risk to groundwater quality is defined as a function of susceptibility, hazard and consequence. Aquifer susceptibility combines the intrinsic susceptibility of the physical system with potential preferential pathways. Hazard threats are assessed based on the potential impact and probability of release. The consequence is the financial cost of the loss of the resource. The risk assessment methodology is applied to the Township of vi
