Five sentences identify one human activity that has increased the amount of lead in drinking water the water filtration Method best suited to remove lead from the drinking water supply

1 answer

One human activity that has increased the amount of lead in drinking water is the use of lead pipes in plumbing systems. Lead pipes can leach lead into the water supply over time, especially in older homes.

The best water filtration method to remove lead from drinking water is reverse osmosis. Reverse osmosis is a filtration process that uses a membrane to remove particles, ions, and other impurities from water. It is effective at removing lead and other heavy metals from drinking water.

Reverse osmosis works by applying pressure to the water on one side of the membrane, forcing it through while leaving contaminants behind. This process can remove up to 99% of lead from drinking water, making it one of the most effective methods for lead removal.

In addition to reverse osmosis, activated carbon filters can also help remove lead from drinking water. These filters work by adsorption, where particles stick to the surface of the carbon, removing lead and other contaminants from the water.

Regular testing of the water supply and replacing lead pipes with safer materials are also important steps in reducing the amount of lead in drinking water and ensuring the safety of those consuming it.
