520 |a"Sulfide-rich mine wastes, when exposed to the atmosphere, will oxidize and release acid and metals to the environment. The release can take place over several decades to many centuries. The timing and duration of peak discharges vary from site to site, depending on the rate and extent of sulfide oxidation, acid neutralization, metal attenuation and release reactions, the groundwater velocity and length of the groundwater flow path. Many oxyanion forming elements such as arsenic, behave quite differently than cation-forming metals, because of their higher mobility under near neutral pH conditions. Field investigations were carried out at mine sites covering a range in age and mineralogy"--Abstract.
