This study was performed to provide basic data necessary for the management of
spring water quality, by investigating water quality characteristics in Seoul during 2016
∼2018. The results are detailed bellow.
In 2016, 2017 and 2018, we surveyed 205, 142, and 183 spring water sources in
Seoul, respectively. The noncompliance rates with the Spring Water Quality Standards
were 31.7%, 34.5%, and 48.6% in each consecutive year. In 2018, the high
noncompliance rate was caused by a large amount of microorganisms and pollutants
being introduced into the water by unusualiy heavy rain during the spring season.
The average and maximum concentrations of As in soil and rock were 0.006 mg/L,
and 0.032 mg/L, respectively, and the average and maximum concentrations of uranium
in soil and rock were 0.0002 mg/L, and 0.102 mg/L, respectively.
