To address these concerns a detailed bedrock mapping project was initiated in 2007 on the Halifax map sheet. The increased growth in the area highlighted the need for geoscience information beyond just knowing areas of potential ARD. Such information is also needed for regional planning, zoning and regulations by various levels of government. The bedrock map can also be used in environmental studies such as waste management, development of regional infrastructure, inventory of natural resources, hydrology and geological hazards.

With the ongoing pressures of growth and development in the Halifax RegionalMunicipality (HRM) many local construction companies and environmentalconsulting groups have contacted the Nova Scotia Department of NaturalResources in regards to outlining areas in the city where acid rock drainage(ARD) may be an issue. To address these concerns a detailed bedrockmapping project was initiated in 2007 on the Halifax map sheet.

The increased growth in the area highlighted the need for geoscienceinformation beyond just knowing areas of potential ARD. Such information isalso needed for regional planning, zoning and regulations by various levels ofgovernment. The bedrock map can also be used in environmental studies suchas waste management, development of regional infrastructure, inventory ofnatural resources, hydrology and geological hazards.
