| Research Abstract |
This study focused on PPCPs contamination of surface water and groundwater in an urban watershed on the Musashino upland, Tokyo Metropolitan Area. PPCPs contamination of groundwater was widely found not only in the urbanized downstream area but also in the sub-urban upstream area, although sewage coverage in the whole area was 100%. In addition, seasonal variation of PPCPs composition in groundwater was observed. That is, understanding of seasonal variation of PPCPs composition is important for evaluation of PPCPs groundwater contamination. This study showed that combination of understanding of PPCPs composition and multi-tracer/multi-isotope approach enables detailed evaluation of the processes of groundwater recharge and hydrogeochemical evolution of groundwater quality.
