One human activity that has increased the amount of lead in drinking water is the use of lead pipes and plumbing fixtures. These pipes and fixtures were commonly used in buildings and homes until the early 1900s. However, they can still be found in some older buildings and homes today.
The most effective water filtration method to remove lead from the drinking water supply is reverse osmosis. Reverse osmosis is a water filtration system that uses a semi-permeable membrane to remove impurities, including lead, from the water. The water is forced through the membrane, which traps the impurities and allows clean water to pass through. This method is highly effective at removing lead, as well as other contaminants, from the water supply. It is also relatively simple and affordable to install, making it a popular choice for residential and commercial applications.
