In 3–5 sentences, identify one human activity that has increased the amount of lead in drinking water. Then explain the water filtration method best suited to remove lead from the drinking water supply.(4 points)
One human activity that has increased the amount of lead in drinking water is the use of lead pipes for plumbing systems. Over time, these pipes can corrode and release lead particles into the water supply. The best water filtration method to remove lead from the drinking water supply is reverse osmosis. Reverse osmosis systems use a semipermeable membrane to effectively remove lead particles and other contaminants from the water, providing safe and clean drinking water.
