Correlations between test methods for the content of organic substances in drinking water were investigated using data of the consumption of potassium permanganate (KMnO4 consumption), total organic carbon (TOC), and UV254 absorbance in several types of drinking water. To determine the amount of organic matter, we took 350 samples of drinking water including 146 samples of groundwater, 102 samples of tap water, and 102 samples of spring water. The data of KMnO4 consumption and UV254 absorbance showed a strong positive linear correlation for all of the samples. The TOC concentration and UV254 absorbance data had correlation coefficients of 0.443~0.490 for groundwater, tap water, and spring water. However, the correlation between TOC concentration and KMnO4 consumption data for groundwater was not confirmed. Their correlation was very low for the data of tap water and spring water though they had statistically significant differences with less than 0.05 of p value. We suggest that the drinking water quality standards for UV254 absorbance should be 0.0600 cm-1, as a result of taking account of an allowance of 25% and other countries' drinking water quality standards. In addition, more studies are needed to set drinking water standards for TOC concentrations which did not show a good correlation with the data of KMnO4 consumption.
Abstract
Correlations between test methods for the content of organic substances in drinking water were investigated using data of the consumption of potassium permanganate (KMnO4 consumption), total organic carbon (TOC), and UV254 absorbance in several types of drinking water. To determine the amount of organic matter, we took 350 samples of drinking water including 146 samples of groundwater, 102 samples of tap water, and 102 samples of spring water. The data of KMnO4 consumption and UV254 absorbance showed a strong positive linear correlation for all of the samples. The TOC concentration and UV254 absorbance data had correlation coefficients of 0.443~0.490 for groundwater, tap water, and spring water. However, the correlation between TOC concentration and KMnO4 consumption data for groundwater was not confirmed. Their correlation was very low for the data of tap water and spring water though they had statistically significant differences with less than 0.05 of p value. We suggest that the drinking water quality standards for UV254 absorbance should be 0.0600 cm-1, as a result of taking account of an allowance of 25% and other countries' drinking water quality standards. In addition, more studies are needed to set drinking water standards for TOC concentrations which did not show a good correlation with the data of KMnO4 consumption.
