Stabilities of pH, electric conductivity and main components of rainwater were investigated under various conditions by using rainwaters collected in Kobe area, to find a suitable sampling and preservation method.<BR>When the rainwater was stored in a polyethylene bottle in the dark at 4°C, concentrations of most components were kept constant for more than five years, but the concentration of NO<SUB>3</SUB><SUP>-</SUP>was slightly increased due to the unknown cause.<BR>The concentrations of the main components in the rainwater stored in a glass vessel were stable on standing in a room for 10-30 days, but on longer standing in a room (about one year), pH value of the rainwater was increased gradually.<BR>Some rainwaters were exceptional and exhibited the changes in both pH value and ammonium concentration, irrespectively of the storage condition.
