Frequently Asked Questions

Filters certified under NSF/ANSI Standard 53 for total lead removal, NSF/ANSI Standard 58 for reverse osmosis, and NSF/ANSI Standard 42 for fine particulates (Class I) effectively reduce lead in drinking water. Always follow the manufacturer's instructions for installation and maintenance to ensure the filter's effectiveness. Contact NSF International at 800-NSF-8010 or visit www.nsf.org for information on performance standards for water filters.

It is a common misconception that boiling water can remove lead, but it does not (TCEQ, 2014). Boiling water can increase the lead concentration since it causes some of the water to evaporate while the lead remains. The most effective way to reduce the risk of lead exposure from drinking water is to use a certified water filter to remove lead or to opt for bottled water for drinking and cooking.

• Run your faucet to ensure that the water that comes out is not stagnant.  If it hasn’t been used for several hours, run the water for three to five minutes (or longer if appropriate given construction practices in the communities served, make sure to check local guidelines to reference flushing protocols) to clear the water that has sat stagnant in the line. (To conserve water, consider catching the flushed tap water for plants or other household use, such as mopping floors.) (TCEQ, 2014)
• Always use cold water for drinking, cooking, and preparing baby formula. Never cook with or drink water from the hot water tap, and never use water from the hot water tap to make formula. (TCEQ, 2014)
• Periodically remove and clean the faucet screen/aerator. While the screen/aerator is removed, run the water to eliminate debris. (TCEQ, 2014)
• Identify and replace plumbing fixtures containing lead. Brass faucets, fittings, and valves may leach lead into drinking water. All brass plumbing fixtures purchased before 2014 should be replaced. Products purchased after that date meet lead-free requirements. (TCEQ, 2014)
• 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. (TCEQ, 2014)
• Consider investing in a home water treatment device or alternative water source. When purchasing a water treatment device, ensure it is certified under NSF/ANSI 53 to remove lead. Search for certified products at NSF International or Water Quality Association.

• Do not boil water to remove lead. Boiling water will not reduce lead. (TCEQ, 2014)
• Do not attempt to change electrical wiring yourself. Improper bonding or grounding can cause electrical shock and fire hazards. (TCEQ, 2014)
