การประเมินคุณภาพน้ำผิวดินของสระน้ำ ในมหาวิทยาลัยเทคโนโลยีราชมงคลอีสาน จังหวัดนครราชสีมา

Abstract

  The purpose of this research was to monitor and analyze the surface water quality of ponds located at the center of Rajamangala University of Technology Isan in Nakhon Ratchasima province. This study took place between September 2018 to February 2019 at six different selected locations throughout the studied regions. The physical and chemical properties of the water were evaluated. Temperature, pH, electrical conductivity, dissolved oxygen and metal content (iron and zinc) of water from all investigated locations were found to be within the acceptable range of surface water quality standard levels. While the biochemical oxygen demand of all sample sites and the total dissolved solid value in region 2 were not statistically significant above the acceptable limit, the findings indicated that the measured parameter values were related to the environment around pond regions. Although and the ponds water became dirty, but the effect was little on the overall quality. Additionally, the water quality remained acceptable for aquatic life, and it had no negative consequences for the ecosystem. This water quality assessment is beneficial since it may be used to participated in the administration of water quality, the improvement of water quality and the treatment of waste prior to its discharge into water resources, and also the prevention of water source contamination.
