Investigation of Environmental Impact, Quality of Life, and Waste Management Behaviors of Residents Surrounding a Solid Waste Landfill: A Case Study of Mukdahan Sub-district, Mueang Mukdahan District, Mukdahan Province

Abstract

Ineffective solid waste management adversely affects the environment and public health, particularly in communities near landfill sites. This cross-sectional descriptive study assessed the environmental impacts, quality of life, and waste management behaviors of residents in Mukdahan Subdistrict, Mukdahan Province. Data were collected from 186 participants using a structured questionnaire and analyzed via descriptive statistics.

The results indicated that residents experienced a moderate level of environmental impact
(Mean = 2.17, SD = 0.74). The most significant concerns were disease vectors, specifically flies
(Mean = 2.70, SD = 0.55), and air pollution characterized by unpleasant odors and particulate matter
(Mean = 2.68, SD = 0.51). Regarding quality of life, residents reported high negative impacts on mental (Mean = 2.37, SD = 0.57) and physical health (Mean = 2.34, SD = 0.61), while economic and social dimensions were moderately affected. Although most residents demonstrated appropriate household practices—including waste separation (99.5%) and proper disposal in bins (97.8%)—structural challenges persist. Major issues identified were the lack of designated waste collection points (54.5%) and insufficient waste bins (33.3%).

These findings suggest that local policy planning must emphasize vector control and the reduction of odor and dust. Recommendations include establishing adequate waste collection points commensurate with volume. Furthermore, implementing respiratory and mental health surveillance, alongside improved community-agency communication, is essential to mitigate environmental impacts and enhance residents' long-term quality of life.
