There are many steps you can take to reduce your exposure to lead in drinking water:
- Run your water to flush out lead. If it hasn’t been used for several hours, run the water for three to five minutes to clear most of the lead from the water. To conserve water, remember to catch the flushed tap water for plants, cleaning or flushing toilets.
- Always use cold water for drinking, cooking, and preparing baby formula. Never cook with or drink water from the hot water tap. Never use water from the hot water tap to make baby formula.
- Do not boil water to remove lead. Boiling water will not reduce lead.
- Periodically remove and clean the faucet screen/aerator. While removed, run the water to eliminate debris.
- You may consider investing in a point-of-use home water treatment device. When purchasing a water treatment device, make sure it is certified under NSF/ANSI 53 to remove lead. You can check to see if the device is registered for sale in California.
- Identify and replace plumbing fixtures containing lead. Brass faucets, fittings and valves may leach lead into drinking water. Products sold in California after 2010 must by law contain very low levels of lead.
- Have a licensed electrician check your wiring. Your home electrical system may be attached to your service line or elsewhere in your plumbing. If this connection is electrified, it can accelerate corrosion. Check with a licensed electrician to correct ground faults and evaluate your local electric code to determine if your wiring can be grounded elsewhere. Do not attempt to change the wiring yourself because improper bonding or grounding can cause electrical shock and fire hazards.
