phosphates in some missouri refractory clays

Water Research CenterPhosphates

 · Phosphates enter waterways from human and animal waste phosphorus rich bedrock laundry cleaning industrial effluents and fertilizer runoff. These phosphates become detrimental when they over fertilize aquatic plants and cause stepped up eutrophication. Eutrophication is the natural aging process of a body of water such as a bay or lake.
