Using Water Testing

What is Domestic Water?

Domestic water is water used for drinking, cooking, cleaning and other daily activities. Contamination of water sources can affect the quality of this water, so regular analysis is necessary. This water is vital for people's health and living standards. The quality of tap water varies depending on the physical, chemical and biological components in the water.

Importance of Domestic Water Analysis

Analyzing water for use is necessary to determine that the water is free of contaminants harmful to health and meets standards. Water quality assessment is important in the following areas:

• Health Safety: Polluted water can lead to waterborne diseases.
• Environmental Protection: Protecting water resources is critical to ecosystem health.
• Agriculture and Industry: Water quality affects the efficiency of water used in agriculture and industry.

Domestic Water Analysis Methods

Regulation on Water Intended for Human Consumption defines drinking and potable water as "water that is generally used for drinking, cooking, cleaning and other domestic purposes and for the preparation, processing, storage and marketing of foodstuffs and other products intended for human consumption, regardless of its origin, in its original or purified form, either from the source or from the distribution network, and that meets the parameter values in Annex-1 and is not offered for sale for commercial purposes".

The results of physical, chemical and microbiological analysis of water used especially in homes and businesses should not exceed the limits specified in the "Regulation on Water for Human Consumption".


The following methods are generally used in domestic water analysis:

• Physical Analysis: Physical properties such as water visibility, color, odor and temperature are assessed.
• Chemical Analysis: pH, hardness, total dissolved solids and pollutants (e.g. nitrate, phosphate) are determined.
• Biological Analysis: Water samples are analyzed for bacterial contamination and the presence of other microorganisms.
• Toxicological Analysis: Water samples are analyzed for the presence of heavy metals and other toxic substances.

Factors Affecting Water Quality

The main factors affecting the quality of domestic water are as follows:

• Sources of Pollution: Industrial wastes, pesticides and domestic wastes can pollute water sources.
• Source of Water: Different sources, such as groundwater, surface water or municipal water, vary in quality.
• Processing Methods: Water treatment and filtration methods can improve water quality.

Domestic water analysis is vital to determine the quality and safety of water. Regular analysis ensures the protection of water resources and safeguards public health. Assessing water quality is a critical step for everyone to live a healthy life.
