Of, relating to, or containing phosphorus, especially with a valence of 3 or a valence lower than that of a comparable phosphoric compound. from agricultural soils. The conclusions evaluate the level of phosphorous reduction achieved when aluminum- and iron-based WTRs are incorporated in high phosphorous soils, when WTRs are blended with organic materials, and when WTRs are applied to a surface during rainfall. The sponsors are Pennsylvania American Water Company, Tulsa Metropolitan Utility Authority, and Denver Water. No index is provided. This is a reprint of the 2006 original edition.
