Final answer:
In areas lacking freshwater, potable water can be obtained through methods such as boiling, filtering, or chemically treating natural water sources. The global water crisis is a significant challenge, underscoring the need for effective management of water supplies.
Step-by-step explanation:
Access to safe drinking water is a critical issue in many parts of the world, with vast disparities in availability and quality between developed and developing nations. Potable water, which is safe for human consumption, lacking harmful chemical pollutants and microorganisms, is not always easily obtainable.
For individuals in areas without freshwater, finding sources of drinkable water is a significant challenge. Engineers and various societies work tirelessly to provide solutions to obtain good drinking water for these populations. In cases where drinking water is scarce or contaminated, some of the methods to produce potable water include boiling, filtering, or chemically treating water sourced from rivers, lakes, or collected rainwater.
These treatment processes aim to remove pathogens and harmful contaminants that can cause serious diseases such as diarrhea, cholera, and typhoid. The global water crisis highlights the importance of managing water supplies effectively to ensure their safety and availability.
