Raised bed test plots containing 15-20 cm of mine tailings from the Old Lead Belt in southeastern Missouri were used in studying the effects of cover materials on leaching of Pb, Cd, Zn, and other chemical constituents from the tailings. The following cover materials, chosen to simulate the effects of vegetative stabilization of tailings piles, were studied: anaerobically digested sewage sludge (''S''), silver maple leaves (''L''), sod (''G''), fertilizer/seed mixture (''F''), and untreated (''U''). The plots were situated outdoors, and the rainfall leachates collected in vinyl receiving pools. Comparison of filtrable metal concentrations in leachates utilized the Bonferroni multiple comparison method (p < 0.05) applied to ranked data. The following effects were observed during the first study season: Pb-L > U > F; Cd-S-L > U; Zn-S > U > F. During the second season, leaching of Pb and Zn from the leaf covered plot was greater than from the control plot.
