Assessment of the drinking water quality from natural sources in the Kharkiv city

Abstract

Water samples from 5 natural springs in the city of Kharkiv were studied. It was determined that according to the organoleptic indicators, no excesses of the normative values are observed, the pH almost does not change seasonally, with the exception of the sample from the "Nemyshlianske" source. The analysis of total alkalinity in the autumn period showed that the standard was exceeded only in samples of the source of the Yunist park and along the street. Klochkivska, and in the spring period - only in the sample of the source on the street. Klochkivska. The iron content exceeds the MPC level only in water samples from the Nemyshlianske spring. 

According to the integral ecological index of water samples in the autumn period from natural sources "Nemyshlyanske", Park "Yunist" and along the street. Klochkivska belongs to the II quality class. The integrated ecological index for all other water samples in the autumn period assigns these sources to the I class of water quality. The calculation of the integral ecological index for water samples from all natural sources in the spring period refers them to the II quality class.
