To comprehend the status of sewer odor-related complaints in Busan Metropolitan City and create a complaint map, we collected and analyzed three years' worth of complaint data, mapping coordinates based on inputted addresses. Sewer odor complaints consistently totaled 1,274 cases over the three years, with a notable concentration in downtown areas. Yeongdo-gu recorded the highest number of complaints in 209 cases (16.4%), while Jung-gu exhibited elevated complaint rates per thousand residents and per square kilometer. Complaints were more frequent in the summer, particularly in June, with 207 cases, compared to the winter season. Recognizing the need for diverse analyses and foundational data for sewer odor reduction, it is deemed necessary to establish a standardized manual incorporating various checklists, in addition to unifying the management of complaint reception desks across districts. As Yeongdo-gu had the highest complaint frequency, a detailed investigation focused on 50 locations examined four sulfur compounds in sewer odors. The contribution analysis revealed hydrogen sulfide as the predominant odorant, constituting 82.74% of the total, reaffirming its significance in sewer odor. Analyzing sulfur compound concentrations by land use indicated higher hydrogen sulfide levels (133.61 ppb) in commercial areas compared to residential and industrial zones. Based on these data, civil complaint map and concentration map of sewer malodor were made using Geocoding tool program, QGIS, R leaflet package and sewerage network diagram layer. With sewer malodor complaints persistently occurring annually, it is expected that the sewer map can serve as foundational data for efficient sewer odor management. In addition, it is judged that continuous and extensive sewer malodor investigation and plateform-type system construction should be conducted focusing on the original citer areas such as Jung-Gu, Seo-gu and Dong-gu, where the frequency of civil complaints was realtively high.
Abstract
To comprehend the status of sewer odor-related complaints in Busan Metropolitan City and create a complaint map, we collected and analyzed three years' worth of complaint data, mapping coordinates based on inputted addresses. Sewer odor complaints consistently totaled 1,274 cases over the three years, with a notable concentration in downtown areas. Yeongdo-gu recorded the highest number of complaints in 209 cases (16.4%), while Jung-gu exhibited elevated complaint rates per thousand residents and per square kilometer. Complaints were more frequent in the summer, particularly in June, with 207 cases, compared to the winter season. Recognizing the need for diverse analyses and foundational data for sewer odor reduction, it is deemed necessary to establish a standardized manual incorporating various checklists, in addition to unifying the management of complaint reception desks across districts.
