This list includes both mines producing acid mine drainage and river systems significantly affected by such drainage.
Historically, the acidic discharges from active orabandoned mines were called acid mine drainage, or AMD.
In Canada, work to reduce the effects of acid mine drainage is concentrated under the Mine Environment Neutral Drainage(MEND) program.

In this application,a slurry of lime is dispersed into a tank containing acid mine drainage and recycled sludge to increase water pH to about 9.
The low pH associated with acid mine drainage(AMD) contributes to the solubility of potential toxic metals that can eventually enter the groundwater system.

Acid mine drainage, acid and metalliferous drainage(AMD), or acid rock drainage(ARD) is the outflow of acidic water from metal mines or coal mines. .
By far, the most commonly used commercial process for treating acid mine drainage is lime(CaO) precipitation in a high-density sludge(HDS) process.
In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, andin such cases it is treated as acid mine drainage(AMD).
