The joint Canada-Alberta implementation plan for oil sands monitoring has done the following: first, increased sampling frequency of air, aquatic life, and water; second, broadened monitoring for contaminants specific to the oil sands; third, introduced new monitoring sites for air, aquatic life, and water; and fourth, created an integrated sampling program to better understand the industry's impact on the regional environment.

(Return tabled) Question No. 152 Ms. Kirsty Duncan: With respect to the development of unconventional gas resources, including shale, tight and coal bed methane, and its possible impacts on the environment: (a) what, if any, research has the government undertaken regarding the development of unconventional gas resources, (i) what was the scope of this research in the areas of, but not limited to, air quality, aquatic and terrestrial ecosystem impacts, economic impacts, occupational risks, public safety concerns, and seismic risks, (ii) what, if any, resources did the government provide for this research, (iii) what, if any, process was e ...[+++]stablished to ensure the independence of the researchers, their research, and their findings, (iv) what, if any, case studies were considered as a part of this research, (v) what, if any, scenarios regarding the development of unconventional gas resources were developed as frameworks for the research, (vi) what economic, environmental and social impacts were identified by this research, (vii) what, if any, priority research areas were identified for further study as a result of this research, (viii) what, if any, departments were involved in this research, (ix) what, if any, action was undertaken to ensure inter-departmental cooperation throughout the research process, (x) what, if any, gaps or weaknesses in the regulatory framework did the research identify; (b) what, if any, research has the government undertaken regarding balancing shale gas' potential contribution to energy security with environmental risks; (c) what are the sources of greenhouse gas emissions associated with unconventional gas; (d) has the government developed a process to determine the overall carbon footprint of shale gas throughout the life cycle of natural gas use, if not, why not, and, if so, (i) what federal departments are involved in this process, (ii) how does the government ensure inter-departmental collaboration on this process, (iii) what is the p ...

The results of the European risk assessment concluded that there was a need to limit the risk to the aquatic compartment from use of acrylamide based grouts in construction applications, and risk to other organisms from indirect exposure through contaminated water from the same application.

In addition to physical-chemical monitoring, we have started to establish a network of biological monitoring that will allow assessing impacts and effects of contaminants on aquatic ecosystems health. In response to (d), the current program provides an adequate picture for basic water quality measures and contaminants in areas of the country where spatial and temporal coverage has been established for some time, e.g., large basins such as the Great Lakes.

Sampling of water bodies is done on a regular or ad hoc basis several times a year for a wide range of physical parameters, chemical contaminants and biological measures, e.g., temperature, dissolved oxygen, nutrients, trace metals, pesticides, presence and diversity of aquatic biota.

In more than one third of the total land of the Mediterranean basin, average yearly soil losses exceed 15 tons/ha [6]. Consequent damage to watercourses follows, through the contamination of river and sea aquatic ecosystems by nutrients and contaminants attached to the eroded soil, with additional other effects such as damage to water reservoirs and ports.
