| Abstract | This study evaluated the long-term environmental effects of applying alum sludge to land. Investigations included soil analysis, soil water monitoring, groundwater monitoring, and analysis of tissues from pine needles. No long-term effects (30 months) were observed, and the authors conclude that alum coagulant sludges can be applied to forest lands at loading rates of at least 1.5 to 2.5 per cent by dry weight without adverse effect. |
