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)

Answer 1

One human activity that has significantly increased the amount of lead in drinking water is the deterioration of old lead pipes used in municipal water systems, often found in homes built before 1986. As these pipes corrode, lead can leach into the drinking water supply, leading to potential health hazards. The best water filtration method to remove lead from drinking water is activated carbon filtration, particularly systems that include specialized lead-removing filters or reverse osmosis. These methods effectively reduce lead levels by capturing and filtering out contaminants, ensuring safer drinking water for consumers.
