Groundwater is the primary source of drinking water for small municipalities and individuals. However, groundwater can be polluted by almost any land use. Consequently, many governments have acquired groundwater information in the aim of protecting the resource. Nevertheless, the resulting data are often ill-fitted to planning needs. In a previous study, a method was developed to help planners interpret hydrogeological data. It combines land planning and hydrogeological data through multicriteria analysis, in order to obtain groundwater contamination risk maps. The method proved efficient and useful. However, it could not be easily implemented by land planners, who do not always have training with these types of data and geographical information system (GIS). This paper presents how the method was integrated into a web-based interface called Aménagement du Territoire et Eau Souterraine (ATES). ATES allows planners to view groundwater basic maps, evaluate the present contamination risk for groundwater, and analyse new planning scenarios. ATES also suggests mitigation measures and offers tools to discuss the possible solutions. The tool has been developed, tested and validated with land planners. To our knowledge, it is the first geo-informatics tool developed especially for planners that aims at facilitating the incorporation of groundwater into planning. Moreover, an innovative approach called MACBETH was used for data aggregation, a novelty in groundwater management and spatial data integration.

In recent decades, governments have developed better knowledge of groundwater and established measures to protect and preserve it. In the hope of protecting this resource and ensuring its sustainability, the Government of Quebec has launched a programme to characterise groundwater in the southern portion of the province. Prior to launching this programme, pilot projects were carried out in two watersheds to produce groundwater atlases. However, the producers of the atlases are under the impression that their documents remain unused by municipal and county planners. The main objective of this study is to propose strategies to facilitate the incorporation of groundwater data into land planning processes. This paper presents the results of a series of semi-directed interviews with land planning stakeholders in the Province of Quebec. The study proposes four actions to improve the use of groundwater information in land planning: an awareness-raising campaign for all citizens, basic training on groundwater for...

Generally, groundwater is naturally of good quality for human consumption and represents an essential source of drinking water. In Canada, small municipalities and individuals are particularly reliant on groundwater, since they cannot afford complex water treatment installations. However, groundwater is a vulnerable resource that, depending on its characteristics, can be contaminated by almost any land use. In recent decades, governments have launched programs to acquire more information on groundwater, in order to better protect it. Nevertheless, the data produced are rarely adequate to be understood and used by land planners. The aim of this study was to develop a method that helps planners interpret hydrogeological data in the Province of Quebec, Canada. Based on the requests and needs of planners during semi-directed interviews, a methodology was developed to qualitatively evaluate groundwater contamination risk by land uses. The method combines land planning data and hydrogeological data through the MACBETH multicriteria analysis method, to obtain maps of groundwater contamination risk. The method was developed through group and individual meetings with numerous hydrogeology, land planning, water's economics and drinking water specialists. The resulting maps allow planners to understand the dynamics of groundwater within their territory, identify problem areas where groundwater is threatened and analyse the potential impact of planning scenarios on the risk of groundwater contamination.

Purpose – Adapting local areas to climate change is a wicked challenge for local administrations. A participatory research is applied to explore how local experience shared by local experts can inform decision and adaptation planning by taking into account local area characteristics and their interrelationships. Methodology/approach – We turned to local actors, who live or work in the city and who can be seen as urban experts. Their experiential knowledge has given us a better understanding of the characteristics of their communities. These experts are likely to possess a representation that reflects the local territorial sensitivities, which can help us determine how these characteristics might be impacted by climate change. Findings – A participatory approach bears many benefits such as mobilizing local stakeholders to find collective solutions. It also allows us to focus on common practices in the urban context, which are likely to be altered by changes in mean temperatures, precipitations, etc. It offers the additional benefit of putting into perspective the relations between a variety of urban issues. Research limitations – A participatory approach means relying on subjective assessments of the possible effects of climate change, which could challenge the relevance of perceived risks and the scope and types of actions taken. Originality/value of paper – The number of the available adaptation planning processes involving community stakeholders and assessments of these processes is very limited. A participatory process such as the cross-sectoral initiative organized in Quebec City can have significant repercussions on local engagement in climate change adaptation. This provides evidence of the potential of deliberation or interaction of territorial actors to improve their understanding of the issues and their adaptive capacity. On a methodological level, the participatory process in itself and the steps to organize it offered a planning frame that can be reproduced.

Groundwater is widely used as a source of drinking water in North America. However, it can be contaminated by microbial or chemical agents potentially hazardous to human health. In recent decades, governments have developed better knowledge of groundwater and established measures to protect and preserve the resource. Several studies have shown that relevant information on groundwater might prove very useful for regional planning purposes. However, there is little information on how groundwater information contributes to decision making in urban and regional planning in Canada and the United States. The objective of this study is to explore the level of use of groundwater information for land use planning purposes in Canada and the United States and to identify the factors that may explain why some provinces or states are more proactive than others when it comes to using such data for groundwater protection purposes. This paper presents the results of a survey sent across North America to groundwater information producers. The resulting data from the survey were examined using descriptive analyses and multiple correspondence analysis, and illustrate how groundwater data can be integrated into land planning.
