The concentrations of inorganic components, 1, 4-dioxane, phenols, and phthalic esters were determined on 5 leachates and 3 treated waters collected at 3 supervisory landfill sites for wastes. Ten inorganic elements such as sodium and potassium were always detected. According to abundance ratio of their molar concentrations, main component was sodium and subcomponent was potassium and calcium/magnesium. The abundance ratio was very much alike between leachate and its treated water in identical disposal site, but it was shown to differ between disposal sites. Chloride ion was always detected in high concentration and ammonium ion was frequently detected in high concentration. According to the ionic balance, cation and anion were balanced in the samples from 2 disposal sites, but cation was more than anion in the samples from 1 disposal site. All samples contained 1, 4-dioxane and the origin is uncertain. Bisphenol A was frequently detected in leachates, but it was easily removed by water treatment process. Phthalic esters were not almost detected in leachates.
