HOW TO REDUCE LEAD IN YOUR DRINKING WATER AT HOME
How Lead Gets into Drinking Water?Where does lead come from? One major source of lead in drinking water comes from old rusty water pipes and eroded natural deposits. Lead also enters water from solder, faucets, and fittings. All from which significant amounts of lead leach into the water – especially hot water. The amount of lead in drinking water depends on:
- the acidity and alkalinity of the water
- the types and amounts of minerals in the water
- the temperature of the water
- how long the water stays in pipes
- the presence of protective scales or coatings inside the plumbing materials
- Behavioral and learning problems
- Lower IQ and hyperactivity
- Slow growth
- Hearing problems
- Reduced growth of the fetus
- Premature birth
- Cardiovascular effects, increased blood pressure and incidence of hypertension
- Decreased kidney function
- Reproductive problems (in both men and women)
How to Reduce Lead in Drinking Water
- Flush your pipes before drinking –The more time water has been sitting in your home’s pipes, the more lead it may contain. Run water for at least 30 seconds or until water is cold to the touch or reaches a steady temperature before using it for drinking for cooking if it hasn’t been used for several hours. This flushes lead-containing water from your fixture.
- Only use cold tap water for cooking, drinking or making a baby’s formula – Do not cook with or drink water from the hot water tap because lead dissolves more easily into hot water, especially for making baby formula. Run cold water until it becomes as cold as it can get.
- Do not boil water to remove lead – Boiling water will not get rid of lead contamination. And be careful of the places you may find lead in or near your home. Paint, soil, dust and some pottery may contain lead.
- Replace your plumbing fixtures if they are found to contain lead – Plumbing materials, including pipes, brass faucets, fittings and valves may contribute lead to your drinking water. Check your plumbing fixtures to see if they are lead-free, and read the labels closely.
- Regularly change or clean your faucet’s aerator – Remove loose lead solder and debris. Every few months remove the aerator from each faucet in your home and flush the pipes for 3-5 minutes.
- Use a refrigerator water filter certified to remove lead – If your home is served by a lead service line, and if lead-containing plumbing materials are found to be in your home, you should consider purchasing a fridge water filter from GlacialPure, where provides high-quality refrigerator filters compatible to various fridge models and tested to IAPMO and NSF/ANSI standards 42&53
