Transboundary aquifers along the Canada-USA border: science, policy and social issues

Since 2005, Canada has followed international developments in transbound-ary groundwater issues in cooperation with its southern neighbor the United States (USA)within the Internationally Shared Aquifer Resources Management Initiative (ISARM) ofUNESCO. As a result, 10 Transboundary Aquifer
Systems (TAS) were identified along theborder between Canada and the USA. This study is an extensive review of the current stateof the 10 TAS. Documentation of scientifically-based knowledge on TAS is an importantstep in identifying potential issues in policies that might be adopted to address
sharedwater-resource issues.New hydrological insights for the region: This analysis emphasizes the need for more sci-entific data, widespread education and training, and a more clearly defined governments'role to manage groundwater at the international level. The study reviews the current
legalframework and summarises the current scientific knowledge for the TAS with respect tothe hydrologic and geologic framework as well as some of the major drivers for supplyand demand. It also describes the links, approach and relevance of studies on the TAS tothe UN Law of Transboundary Aquifers
and on how these might fit in the regional strategyfor the assessment and management of the TAS. Clear communication, shared knowledgeand common objectives in the management of TAS will prepare the countries for futurenegotiations and cooperative binational programs.
