Lead in Drinking Water
What is Lead?
Lead is a naturally occurring metal found throughout our environment. It often enters drinking water through the corrosion of lead-containing materials in household plumbing, especially in older homes. Lead piping was commonly used before 1930, but even after its replacement with copper pipes, lead-based solder was still employed until it was banned in North Carolina in 1985. Today, brass materials with less than 8% lead are used in nearly all residential, commercial, and municipal water systems, which has greatly reduced lead levels in drinking water.
Testing Requirements
The Town of Greenevers must test for lead and copper every three years. During these testing periods, samples are collected from the water supply and analyzed to ensure compliance with safety standards. A first-draw sample is taken after the water has been stagnant in the plumbing for at least 6 hours, typically overnight.
How to Minimize Lead Exposure
You can help reduce or prevent lead exposure in your tap water by following these tips:
- Run Cold Water: Flush your tap by running cold water for 1 to 2 minutes before using it for drinking or cooking if the faucet has been unused for over 6 hours.
- Flush Each Faucet: To save water, use the flushed water for purposes like watering plants or washing dishes. Consider filling a few bottles of water after flushing to avoid daily flushing.
- Avoid Hot Water for Cooking: Hot water dissolves lead more quickly than cold water. Use cold water for cooking and making baby formula, heating it on the stove or in the microwave.
- Clean Faucet Strainers: Periodically remove and clean faucet strainers to clear loose debris by running the water for 3 to 5 minutes.
