For example, the value of HQ indicates that the probability of getting a health injury is 5%. However, the level of concern does not increase linearly as the RfD is approached or exceeded because RfD does not have the same accuracy or precision as the level of concern and is not based on the same severity of toxic effects [7]. RemediationTechnique Selection Module A number of technologies are available to remediate groundwater contaminated by coalmining activities. Groundwater remediation methods can be classified into two classes: in situ and ex situ methods. In situ methods treat polluted groundwater in place, while ex situ methods excavate contaminants and transport them offsite for treatment. The methods for treating AMD may be active and passive. Since it is difficult for the user to select a suitable remediation technique for the specific sites, the decision support system can support the decision making process. The user can input the required data such as site characteristics and the parameters for numerical simulation through the friendly user interface. GCDSS can evaluate various binations of remediation techniques and AMD treatment methods and identify an optimal strategy for groundwater pollution control at a specific coalminig site. 4 Conclusions In this study, an integrated decision support system (GCDSS) is proposed for groundwater pollution control at coalmining contaminated sites. Through the developed GCDSS, the functions of mine characterization, numerical modeling, risk assessment and remediationtechnique selection are effectively integrated. The user can access various resources within this system and obtain support on selection of different remediation technologies.

Chan Faculty of Engineering/Energy Informatics Laboratory University of Regina Gordon Huang Faculty of Engineering University of Regina Abstract: Groundwater contamination is one of the major environment concerns at coalmining sites. Highly saline or highly acidic water from coalmining can introduce serious pollution to groundwater and adversely affect its quality. This impact may last a long time even
