Introduction
Shingashi The Shingashi River basin used to be a region where water quality deteriorated significantly, but in recent years the water quality has been improving due to basin sewerage and hydrophilic projects. However, there are still some areas where the water quality has not improved in the upper reaches of the tributaries located in the Sayama Hills. Based on the results of river surveys around the Sayama Hills over a two-year period, additional surveys will be conducted to identify pollution sources, and the characteristics of the water environment centered on water quality will be considered.
Conclusion
In the upper reaches of the Rokuya River, the water quality of the final waste disposal site affects EC, and in the Karabori River, the load of EC and COD is increasing due to the influence of wastewater from dairy products factories in the middle basin. We would like to continue the survey and reflect the analysis results of the main dissolved components in the research.
