Includes bibliographical references (pages 61-64). "The Vancouver Island Region Watershed Protection Steering Committee initiated a collaborative project beginning in 2006 between the BC Ministry of Environment, Vancouver Island University, Natural Resources Canada, Vancouver Island Health Authority and Regional Districts on Vancouver Island to assess the relative vulnerability of the groundwater resources to contamination from surface sources. The need for this type of assessment was highlighted by increased development pressures coupled with industrial and agricultural land use activities that may threaten the quality of ground and surface water supplies. The vulnerability of aquifers to contamination needed to be characterized in order to be considered alongside other social, economic and environmental priorities for Vancouver Island and the province, as part of the comprehensive land use planning process. … This document details the methods used to produce intrinsic aquifer vulnerability maps for the regional districts of Nanaimo (RDN) and Cowichan Valley (CVRD) study area, and may be used to update these maps in the future or guide the application of these methods to other areas of Vancouver Island. …"--Executive summary, pages iv, v.
