[O07-P57] Environmental impact assessment of air and soil substances using spring water of Minowa as an index

*Mari Taki1, Shohei Nanri1 (1.Ichikawa gakuen Ichikawa senior high school)

Keywords:Spring water, Ichikawa, Chiba

In this study, air temperature, water temperature, pH, RpH, electrical conductivity, and COD were measured in the spring water of Minowa, Ichikawa City, Chiba Prefecture.
The pH value was lower than the RpH value, and it was found that the electrical conductivity depends on the amount of precipitation. COD was measured from September 18, 2020 to December 11, 2020. As a result, although there are some fluctuations, it was clarified that the water quality is generally good according to the graph of the environmental standard (lakes) regarding the conservation of the living environment of the Ministry of the Environment.
