In 3–4 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.

Answer 1

One human activity that has increased the amount of lead in drinking water is the corrosion of lead pipes and fixtures. The best water filtration method to remove lead from the drinking water supply is reverse osmosis. Reverse osmosis works by pushing water through a semipermeable membrane to remove contaminants, including lead, effectively providing clean and safe drinking water.
