The committee called for speedy engagements with potential off-takers of partially treated acid mine water
, as this has potential to bring in additional revenue that could assist in dealing with the challenge.
Moreover, characteristics of the water extracted from coal samples in the laboratory clearly revealed that the coal seam had fair tendency to produce acid mine water
Freely suspended on 430-m-long duplex steel pipes, they transport the acid mine water
to the surface and then into the plant where the pH value is raised by adding lime to neutralize the acid and precipitate dissolved metals as hydroxides.
There are these reports on "direct discharge of tailings into rivers, periodic flooding and escape of acid mine water
, collapse of tailings and waste rock piles, and contamination of soils and the food chain from heavy metals and other compounds."
Topics presented included Penn State research on plant nutrients; the uses of mushroom compost for field crops; for storm water basins and stream restoration projects; for abandon mine reclamation and acid mine water
A flooded mine is a permanent source of acid mine water
with stabilized (or balanced) composition.

by Use of Heavy Metal Precipitation and Ion Exchange," Minerals Eng., 136(6), 623-642 (2000).
When the mining ceased, the mines began to fill once again with water resulting in "acid mine water
" surfacing and flowing into Tar Creek and the public water supply wells.
So, the butte became a perpetual caldron for brewing metals-laden acid mine water
that flows out and down the mountainside.
Microbes and sedimentation, microbial leaching of metals from ores, acid mine water
pollution, and the microbial ecology of marine and freshwater habitats are covered.
