Abstract

The nonpoint pollution source (NPS) is irregular in the amount of generated and runoff. About 70% of the water pollution sources in Korea are NPS. Most of the rural areas are small towns with less than 50 families. This is where sewerage supply is poor. This is where the domestic swage of the house flows directly into the small stream. This study investigated the amount and concentration of domestic swage. And investigated NPS for public officials. We have suggested an improvement plan here. Local government officials lack the concept of NPS. Rural residents also do not know about NPS. Therefore, we proposed NPS public relations and education linked to public administration. This is an extension of the national budget and interest. The domestic swage is discharged at about 272 liters per day in a house. We proposed the introduction of small facilities. If the capacity remains, it is suggested to link to cattle shed, pigsty and so on. The BOD, COD, TN, TP, and SS concentrations were all high. This suggested a reduction in concentration in combination with natural water. Finally, NPS facilities were proposed to be put into rural areas. And it was determined that continuous monitoring was necessary. The results of this study were expected to be applied to NPS management.
