What are the Dangers of Lead Contamination?
Exposure to lead in water affects all age groups, but young children and pregnant women are at the highest risk.
The potential health effects include:
- Fatigue
- Weakness
- Headaches
- Abdominal pain
- High blood pressure
- Learning disabilities
- Behavioral problems
- Slowed growth
- Infertility
- Miscarriage
- Nervous system damage
- Coma and death
According to the Centers for Disease Control and Prevention, lead paint chips remain the primary cause of lead poisoning in children, but there are nearly 200,000 cases in the US annually to which lead-contaminated water contributes.
How Does Lead Get into the Drinking Water Supply?
Lead is rare in lakes and rivers, so how does it get into your tap water? The problem is our infrastructure. Lead was once a miracle metal for plumbing applications, so it’s in many of the underground service lines that distribute water from treatment plants to homes.
According to the Environmental Protection Agency, lead in pipes is relatively stable as long as the pH and temperature of the water are carefully controlled. But as the Flint Water Crisis demonstrates, treatment errors occur.
Lead pipes and lead solder are also common in pre-1986 houses. Lead was permitted in well pumps and plumbing fixtures until 2014, and even modern homes with copper pipes may have lead soldering. It could take decades to get lead out of our water supply.
Methods to Remove Lead from Drinking Water
There are several effective methods to remove lead from drinking water:
- Filtration Systems: The Best Way to Remove Lead Activated carbon filters and reverse osmosis (RO) filters are highly effective in removing lead from water. Activated carbon filters use adsorption to trap impurities, including lead particles, ensuring clean and safe drinking water. RO filters utilize a semi-permeable membrane to separate impurities from the water, removing up to 99% of dissolved solids, including lead.
- Distillation: A Reliable Method for Purifying Water Distillation involves heating the water until it vaporizes and then condensing the steam back into liquid form. This process effectively removes lead and other contaminants with higher boiling points than water.
- Ion Exchange: Effective Removal of Heavy Metals Ion exchange filters replace lead ions in the water with other ions attached to resin beads or zeolite materials. This method works exceptionally well for removing heavy metals like lead.
- Point-of-Use Filters: Targeted Filtration at Specific Sources Point-of-use filters offer a convenient solution for specific faucets or sources of water in your home. These filters can be directly installed on the faucet or under the sink, providing targeted filtration for that specific source.
- Whole House Filtration Systems: Comprehensive Protection for Your Home Whole house filtration systems ensure lead-free water throughout your entire home. These systems are typically installed at the main water line and filter all the water before it reaches any faucets or appliances.
Choosing the right lead removal method for your drinking water is crucial. Consider factors like effectiveness, cost, ease of use, maintenance needs, and compatibility with your plumbing system. Don’t forget to regularly test your water after implementing any method to guarantee its ongoing effectiveness.
