    Limestone Sand: Pros and Cons - Penn State Extension

    The stream to which limestone sand is applied may be impaired for some distance downstream as a result of aluminum precipitates and substrate covering. If such impairment is judged to be acceptable based on overall watershed water quality and aquatic biota restoration goals, limestone sand remains a cost-effective acid water mitigation tool.

    Acid Mine Drainage In Pennsylvania Streams: Ironing

    Open Limestone Channels . In coal mining regions, limestone is prevalent and therefore is the least expensive buffer material. This led to construction of open limestone channels to pre-treat AMD effluent. Open limestone channels raise the pH of effluent by the reaction of calcite with carbonic acid: CaCO. 3 + H. 2. CO. 3 → Ca. 2+ + 2HCO. 3-.
