For example, the World Health Organization (WHO) provides detailed guidelines for water quality, including maximum permissible limits for organic and inorganic matter, microorganisms, and radioactive materials. In addition, countries set local standards that are appropriate to environmental conditions and available water resources. In Saudi Arabia, water companies adhere to the standards of the Saudi Food and Drug Authority (SFDA), which are consistent with international standards. These standards include conducting periodic checks on water at all stages of production, from source to packaging, to ensure that it is free of contaminants and safe for human consumption. Compliance with these standards ensures that consumers receive safe and healthy drinking water.

2. Different drinking water sources: An overview

2.1. Surface and groundwater: Advantages and disadvantages

Drinking water sources vary between surface and groundwater, each with its own advantages and disadvantages. Surface water, such as rivers and lakes, is a plentiful source of water, but it is more susceptible to pollution due to direct exposure to environmental factors and human activities. Surface water requires intensive treatment processes to remove organic, chemical, and microbiological contaminants before it becomes potable. Groundwater, which exists in rock layers beneath the Earth's surface, is characterized by its relative purity and protection from surface pollution. However, groundwater may contain high concentrations of minerals and salts, such as calcium and magnesium, which require treatment to remove these substances and improve the taste of the water. In addition, extracting groundwater can be costly and requires the use of advanced technologies to drill wells and pump water. Therefore, each source of water must be carefully studied and evaluated to determine the best ways to exploit it and ensure water quality.

2.2. Seawater desalination: Technologies and challenges

Seawater desalination is considered a strategic solution for providing drinking water in areas suffering from a shortage of fresh water resources, such as Saudi Arabia and the Gulf countries. The seawater desalination process relies on advanced technologies to remove salts and minerals from saltwater, making it suitable for drinking and other uses. Among the most common technologies for seawater desalination are multi-stage flash distillation (MSF) and reverse osmosis (RO). Reverse osmosis technology is characterized by its high efficiency and low energy consumption, making it the preferred choice in many modern desalination plants. However, the seawater desalination process faces environmental and economic challenges. Desalination plants require significant investments in infrastructure and technology and consume large amounts of energy, which increases greenhouse gas emissions. In addition, the desalination process produces large amounts of concentrated brine that must be disposed of safely to protect the marine environment. Therefore, more sustainable and efficient desalination technologies must be developed to reduce the environmental and economic impact of this process.

3. Stages of drinking water treatment: From purification to disinfection

3.1. Primary purification processes: Clarification and filtration

Primary purification processes are a fundamental step in drinking water treatment, aimed at removing suspended solids and large impurities from the water. These processes include clarification and filtration, which work together to improve water quality and reduce the burden on subsequent treatment stages. In the clarification process, chemicals such as alum are added to the water, which leads to the aggregation of fine particles and impurities to form large masses that settle at the bottom of the tank. After that, the pure water is separated from the sediment. The filtration process, on the other hand, relies on passing water through layers of sand and gravel to remove fine particles and remaining organic matter. Primary purification processes contribute to improving the transparency of the water and reducing the concentration of suspended solids, making it more amenable to treatment and disinfection. Attention to these initial stages ensures that pure and healthy water is obtained.

3.2. Disinfection processes: Chlorine, ozone, and ultraviolet radiation

Disinfection processes are the last and most important stage in drinking water treatment, aimed at eliminating disease-causing microorganisms, such as bacteria, viruses, and parasites. Several methods are available for disinfecting water, including the use of chlorine, ozone, and ultraviolet radiation. Chlorine is one of the most commonly used chemicals in water disinfection, characterized by its high effectiveness and low cost. However, chlorine may cause the formation of harmful by-products, such as trihalomethanes (THMs), which can be carcinogenic. Ozone is considered an effective alternative to chlorine, as it is characterized by its high oxidation capacity and destruction of microorganisms without forming harmful compounds. However, ozone is less stable than chlorine and does not provide long-term protection against subsequent contamination. Ultraviolet radiation is a safe and effective method for disinfecting water, as it destroys the DNA of microorganisms without adding any chemicals to the water. The appropriate method for disinfecting water must be selected based on local conditions and the quality of the raw water to ensure safe and healthy drinking water.

4. The role of laboratories in testing water quality

4.1. Physical and chemical tests

Laboratories play a vital role in testing water quality and ensuring its safety for human consumption. The tests conducted in laboratories include a comprehensive analysis of the physical and chemical properties of water to determine the extent to which it complies with health and environmental standards. Physical tests include measuring temperature, turbidity, color, odor, and taste, while chemical tests include determining the concentration of organic and inorganic matter, such as minerals, salts, and harmful chemicals. Advanced equipment is used to perform these tests with high accuracy, such as spectrophotometers and gas chromatography devices. The results are analyzed and compared with the specified standards to assess water quality and determine whether additional treatment is needed. Conducting physical and chemical tests regularly ensures early detection of any pollution or change in water quality and taking the necessary measures to maintain the health of consumers.

4.2. Biological and microbiological tests

In addition to physical and chemical tests, laboratories conduct biological and microbiological tests to determine the presence of disease-causing microorganisms in drinking water. These tests include the detection of bacteria, viruses, and parasites that can cause infectious diseases. Advanced techniques are used to culture microorganisms and determine their types and concentration in water. Tests are also performed to detect biological indicators, such as coliform bacteria, which indicate fecal contamination. Laboratories rely on strict standards to ensure the accuracy and reliability of results and are committed to conducting tests regularly in accordance with the specified programs. Conducting biological and microbiological tests ensures the protection of consumers from waterborne diseases and contributes to maintaining public health.

5. Bottling and packaging: Ensuring water safety until consumption
