The bedrock acid rock drainage potential digital product for southwestern Nova Scotia illustrates the potential of bedrock to generate ARD if physically disturbed or exposed. The purpose of this digital product is to inform landowners, developers and municipal planners about the geological hazard of acid rock drainage (ARD) and to identify where the bedrock in southwestern Nova Scotia is potentially sulphide-bearing and may develop ARD if physically disturbed or exposed. Disturbing the bedrock refers to activities that physically alter and/or expose the bedrock, such as drilling, blasting and excavation.There are three ARD potential categories: high, moderate and low. This data is intended to be used as a tool for making land-use and environmental planning decisions by indicating where precaution is needed, or further lithogeochemical analysis is likely required, before engaging in activities that disturb or expose bedrock.
