Abstract
One of the main problems of rural residential areas is
to provide the local population with quality drinking water,
which is a major factor influencing their health. To solve this
problem, it is necessary to implement effective measures not
only at the state level but also at the regional and local levels.
The main purpose of decentralization of power is to transfer the
power and appropriate financial resources to the lowest levels
of local self-government, which makes it possible for created
amalgamated communities to use these resources to solve the
priority issues. However, to determine the ecological state of
rural settlements in the subsystem of drinking water quality, it
is necessary to assess its quality in the territory where the
community is situated. The investigation was carried out in 15
rural settlements of the Teterivka amalgamated community of
the amalgamated Zhytomyr district. 36 water samples were
selected from the sources of non-centralized water supply.
Water quality classes were determined following DSTU
(National Standards of Ukraine) 4808:2007 “Sources of
Centralized Drinking Water Supply. Hygienic and Environmental
Requirements for Water Quality and Selection Rules”. As a
result, it has been established that nitrates make the largest
contribution to the pollution of drinking water. In 47 % of the
selected samples, the nitrate content on average exceeded the
norm; and in 46.7 % of the investigated settlements, water
belongs to quality class 4, defined as “mediocre”, “partially
potable” of undesirable quality. A critical situation was
recorded in the villages of Mykhailivka, Nova Rudnia and
Staroshiika, where the nitrate content in all selected samples of
the well water exceeded the norm. On average, 61 % of the
selected water samples did not meet the standard and were
below the standard. According to the pH indicator, the quality
classes vary from “excellent”, very pure water grading to the
class of “good”, pure water of the desired quality to
“satisfactory”, slightly contaminated water of acceptable
quality. The total iron content exceeded the standard in 5.6 % of
the selected samples.
