Modeling of chloroform content in drinking water of infiltration water intake by periods of the annual cycle. Part 1. Extended flood period

Abstract

Abstract A relationship was found between the chloroform content in drinking water and the parameters characterizing the water quality (turbidity, chromaticity, oxidizability) during the extended flood period (March - June), isolated from the eighteen-year period of the infiltration water intake operation. Two time series were formed, including the monthly average values of the parameters for the entire observation period (72 values) and the averaged values of the parameters corresponding to each year (18 values). Two time series were formed, including the monthly average values of the parameters for the entire observation period (72 values) and the averaged values of the parameters corresponding to each year (18 values). Correlation-regression analysis showed that none of the parameters have a decisive significance for the chloroform content. Multiple correlation-regression analysis revealed that the regression equation for the time series of the averaged values of the parameters corresponding to each year is statistically reliable, is characterized by an acceptable mean error (about 12%) and can be used to assess the chloroform content in drinking water.
