Final answer:
Individuals in areas without freshwater can use reverse osmosis and inline water filters to make water safe for drinking. These technologies remove contaminants and ensure water quality, similar to monitoring practices like those in New York City.
Step-by-step explanation:
For individuals living in areas without access to fresh water, producing water that is safe for drinking requires specific technologies that can remove contaminants and purify water. One such technology is reverse osmosis. This is a filtration method that removes many types of dissolved and suspended chemical substances, as well as biological ones (like bacteria), from water by pushing the water under pressure through a semi-permeable membrane.
Another method that can be used is inline water filters, which are capable of reducing the concentration of solutes in tap water that may contain trace levels of contaminants, thereby making the water safe for drinking and cooking. In addition to these methods, some areas may also employ advanced treatment and distribution facilities to monitor and maintain water quality, ensuring that the drinking water is safe for the community, similar to the system in place in New York City.
