Abstract
<p>We investigated the properties of organic matter indicators in water collected at landfill sites in Fukuoka prefecture, Japan. A linear relationship was observed between total organic carbon (TOC) and chemical oxygen demand (COD).However, no clear relationship was found between TOC and biochemical oxygen demand (BOD). This lack of a relationship was inferred to attribute to the influence of bacterial nitrification on BOD. Next, we evaluated of water quality characteristics by using organic matter indicators and inorganic ion components. The results of principal component analysis showed that the primary component indicated the total amount of pollution, and the secondary component indicated the balance of organic and inorganic components of the contamination. The landfill related water was classified into seven groups by the results of cluster analysis. The radar chart of each group was made using water quality indicators, which were the ratios of the average of each group to the average of all samples. The shape of the radar chart of each group was consistent with the component type based on the principal component scores, and it was possible to visualize the differences among the water groups. In addition, we investigated data on leachate collected during a period, in which hydrogen sulfide gas was generated, and the resulting radar chart showed that organic matter indicators tended to be higher. These results indicated that the method of evaluating water quality used in this study was effective for understand the characteristics of water quality for the proper management of waste landfill site.</p>
