ENVIRONMENTAL ASSESSMENT OF DRINKING WATER QUALITY IN MODERN RESIDENTIAL COMPLEXES IN NASIRIYAH CITY

Abstract

Water is the foundation of life, directly linked to the lives of humans, animals, and plants. Therefore, it must be preserved and maintained to preserve the balance of
its ecosystem. This system is suffering from a clear and noticeable decline due to pollution in drinking water, which is one of the most complex problems threatening
life in general. Through field studies and laboratory samples of the reality of residential complexes to study some of the physical and chemical properties of drinking
water belonging to water purification plants and government stations in the center of Nasiriyah district, This was done by measuring some variables and comparing
them to standard values. Some physical and chemical properties were studied, such as electrical conductivity (EC), pH, total dissolved solids (TDS), turbidity (NTU),
and temperature. The research also addressed finding the concentration of some chemical elements, such as suspended solids (TSS), chlorides (Cl), sulfates (SO4),
calcium (Ca), and magnesium (Mg). Comparing them with local and international standards and determining the extent of their compliance, and whether they fall
within the parameters or exceed the parameters and standards.
The study demonstrated clear pollution resulting from changes in the physical and chemical properties of certain elements, negatively impacting the lives of living
organisms in general and humans in particular.
