Water Treatment Residuals (WTR) are primarily sediment, metal (alumunium, iron, or calcium) oxide/hydroxides, activated carbon, and lime removed from raw water during the water purification process. The effectiveness of WTR in reducing soluble [[phosphorus]] depends on several factors, including source water characteristics, water treatment methods, and length of residual storage time prior to land application. Different water treatment facilities create different physical and chemical compositions and phosphorus sorption capability of WTR.<ref name=Agyin>Agyin-Birikorang S, O’Connor G, Obreza T.
