i was listening to public radio (its a fm station) and they mentioned that the state was working with the skokomish tribe to get them to dispose of the chums in a differant manner, the sate says that the chums contributed to 20% of the problem with lack of oxygen and 40% from the sewers/septic systems and i forget the other contributing factors.. i dont see why the state doesnt put in a bunch of pump systems that pump the air thru pvc pipes with holes drilled into it to get some oxygen down there for a temporary solution? it works in a aquarium, why not the sound?
