In small controllable colonies it works better than anything else I have
used.It will not overwinter where I am
so I kept some in an old freezer filled with water with a glass top covered
with insulation on cold nights.
it will turn murky nutrient polluter water crystal clear in not time at all.

Some else suggested using this method;

"You could do mycoremediation with mushroom spawn and woodchips. For
example, you could put mushroom spawn (oyster mushroom is good) in
woodchips in gunny sacks and let the mycelium grow for awhile then secure
them in a slow part of the creek so the water passes through and is cleaned
by the mycelium. The mushrooms break the toxins down into their basic
elements so they are no longer toxic."
