Sustainable Development of Clean Water and Sanitation

Topic Information

Dear Colleagues,

Currently, approximately 2.2 billion people worldwide lack access to safe drinking water, while 4.2 billion people do not have access to adequate sanitation services. This crisis disproportionately affects women and girls, who are often responsible for collecting water and are vulnerable to violence and the health risks associated with poor sanitation. By utilizing isotopic techniques, the quality and quantity of water resources can be studied. Naturally occurring isotopes in water are used to determine where the water came from, its age, its susceptibility to contamination, and how water resources move and interact above and below ground. Isotopic techniques are also employed to better understand and adapt to the effects of climate change, and to map the size of water resources, including groundwater reservoirs hidden underground. The quality of water is often affected by human activities and infrastructure, making this source of life a threat to life. Water sources can be contaminated with heavy metals, complex organic compounds (such as petroleum byproducts or pharmaceuticals), radioactive isotopes, and trace elements. This can affect not only humans, but all forms of life. Nuclear and isotopic techniques are used to detect and analyze contaminants and track their movement. Certain contaminants in wastewater produced by industrial processes can also be destroyed using techniques such as electron beam irradiation. This can enhance the cleanliness and safety of water for the environment.

Triiodide resin has an antimicrobial effect on bacteria in water. In the traditional TR manufacturing method, potassium iodide (KI) and crystalline I₂ are reacted to form triiodide ion (I₃⁻). However, I₂ is difficult to use and store because it is vaporizable and poorly soluble in water. This study was conducted to develop a method of producing triiodide resin (TR) without using crystalline I₂. A chemical radical reaction between a commercially available peracetic acid (PAA) solution and a potassium iodide (KI) solution was used to produce I₂ and I₃⁻ ions, which combined with a strong basic anion exchange resin to produce TR. The disinfection of pathogenic microorganisms (e.g., Escherichia coli, Salmonella spp.) present in anaerobically digested livestock wastewater is essential prior to its discharge into public water systems or marine environments, in order to safeguard environmental integrity and public health. Anaerobically treated contaminated livestock wastewater was sterilized through three rounds of treatment with a TR column and prepared by the oxidation of a 100 mM KI solution. Full article

Various groups of contaminants can be found in water intended for human consumption, such as bacteria, viruses, chemicals, and heavy metals. Many of these contaminants can cause serious health problems, so it is extremely important to ensure that water quality meets current standards. The main objective of this study was to analyze and evaluate the variability of drinking water quality in a selected water supply system located in the southern part of Poland. The results of the research and analysis presented in the study were prepared on the basis of test reports carried out by the water supply company during the operating years 2018–2022. A total of 28 indicators from the group of physicochemical and microbiological parameters were analyzed: color, turbidity, pH, electrical conductivity, nitrates, nitrites, chlorides, chromium, aluminum, cadmium, magnesium, manganese, copper, nickel, lead, mercury, sulfates, total iron, oxidizability, chloroform, total THM (Trihalomethanes), total organic carbon, chlorites and chlorates, Escherichia coli, Enterococci, Coliform Bacteria, Clostridium perfringens (with spores), and total hardness. The results obtained were compared with national and European standards. The analyzed tap water was characterized by a stable physicochemical composition and did not exceed microbiological parameters. The only parameter that would not meet the acceptable value is chromium. Its value in each of the analyzed months was <3.0 μg/L, while the new directive tightens the requirements to 0.25 μg/L. The water supply network operator should take action to reduce the amount of chromium in tap water so that it follows the introduction of new regulations on the quality of drinking water.
