The Environmental Safety Company (EPA) regulates public water methods and units “protected” limits for particular pollution in water. And though you’ve in all probability heard numerous headlines about lead in consuming water, there’s no approach such a toxic steel could possibly be in your treasured water provide. Proper?
Sadly, that’s not at all times the case. The Pure Sources Protection Council (NRDC) discovered that between January 1, 2018, and December 31, 2020, over 18,000 neighborhood water methods serving greater than 186 million Individuals had some water samples with lead ranges over one half per billion. So, if a public utility provides your consuming water, it probably accommodates lead – much more so in case your water comes from a non-public nicely.
Lead is poisonous to people, animals, and different life types, and in response to scientists, there’s no protected stage of publicity to the steel. Meaning even low concentrations may cause irreparable well being issues and loss of life. Kids, particularly fetuses and infants, are essentially the most weak, however all of us ought to attempt our greatest to cut back our danger of publicity to this dangerous neurotoxin.
Let’s begin by how lead will get into water provides, the doable well being results of lead publicity in adults and youngsters, and learn how to take away it from consuming water.
How Does Lead Get into Faucet Water?
Even when your water is lead-free on the supply, it may be contaminated because it travels to your faucet. However how is that this doable?
When lead family plumbing and municipal service strains corrode
In keeping with the CDC, “Sure pipes that carry consuming water from the water supply to the house might comprise lead. Family plumbing fixtures, welding solder, and pipe fittings made earlier than 1986 can also comprise lead.”
When water passes via lead plumbing supplies in your house’s water supply system, a chemical response happens, dissolving or sporting away pipes, solder joints, brass alloy taps, and different plumbing fixtures. The corrosion causes lead particles to leach from the plumbing supplies and dissolve into the water because the water sits within the pipes or travels alongside them to your taps. And until you’ve a system that filters lead out of your water provide, you danger ingesting the steel, assuming you drink faucet water at residence or use it to arrange meals and drinks.
However even when your private home’s piping system is lead-free, there’s a risk that your water can decide up lead via municipal pipelines because it travels to your private home. Whereas many cities and states have performed a wonderful job of guaranteeing public pipe networks, which ship water to giant geographic areas, at the moment are lead-free, tens of millions of lead service strains nonetheless join properties to water mains. When these pipes are uncovered to water with excessive acidity or low mineral content material, or the water sits too lengthy inside them, it might corrode the pipes, leaching lead from them and contaminating the water flowing to your faucet.
The quantity of lead that leaches into the water is determined by the next:
- the water temperature,
- the quantity of wear and tear within the pipes,
- how lengthy the water stays within the water strains,
- the acidity or alkalinity of the water,
- the categories and quantities of minerals within the water,
- the quantity of lead that water comes into contact with, and
- the presence of protecting scales or coatings within the pipes.
When industrial exercise leaks lead into your nicely water
Not solely can lead enter consuming water from elements of the nicely system and the house’s plumbing, however industrial actions like mining and coal burning can leak the steel into nicely water.
Lead in excavated rock or underground mines can are available contact with water saved in aquifers that provide water to wells. Water discharges from mining areas can even leach lead and carry it towards water wells throughout flooding or heavy rainfall. If the nicely is constructed poorly or maintained inappropriately, it might enable the contaminant to enter the nicely system and contaminate the water.
How A lot Lead is Secure in Ingesting Water?
The Secure Ingesting Water Act (SDWA) requires the EPA to determine contaminant ranges in consuming water at which no adversarial well being results are prone to happen, with an enough margin of security. These non-enforceable well being objectives, primarily based solely on doable well being dangers, are known as most contaminant stage objectives (MCLGs).
Whereas the EPA mandates public water methods to switch 3% of their lead service strains annually if lead concentrations exceed 15 components per billion (ppb), the company has set a public well being purpose for lead in consuming water at zero – and rightfully so.
Lead isn’t solely dangerous to well being at low ranges but additionally can accumulate within the physique over time, permitting low-level publicity to result in high-level well being issues. So, decreasing your publicity is essential!
The SDWA considers a plumbing fixture “lead-free” if it has lower than a 0.25 p.c weighted common of lead throughout its floor. Nonetheless, “lead-free” doesn’t at all times imply zero lead. Small quantities of the steel can nonetheless leach into consuming water.
Is Lead in Ingesting Water Harmful?

Furthermore, their rising our bodies take in 4-5 occasions extra of the steel than adults, and their brains and nervous methods are extra inclined to the steel’s damaging results. It’s heartbreaking certainly, particularly since kids are uncovered to excessive ranges of lead via their water provide in roughly 4 million properties throughout america.
Whereas adults can usually tolerate increased ranges of lead publicity than kids, they don’t seem to be proof against its dangerous results. Pregnant ladies and their unborn infants are much more in danger, as lead publicity may cause numerous well being issues. Moreover, the signs of lead poisoning don’t often seem till harmful quantities have collected.
Lead Poisoning Signs in Newborns and Younger Kids

- Be born prematurely
- Have decrease start weight
- Have slowed progress
Younger kids might endure from the next:
- Decrease IQ

Lead Poisoning Signs in Adults and Pregnant Girls
- Kidney harm
- Reproductive issues
- Cardiovascular issues
- Joint and muscle ache
- Stomach ache
- Temper problems
- Elevated danger of hypertension
- Diminished sperm depend and irregular sperm
- Difficulties with reminiscence or focus
Pregnant ladies might expertise signs equivalent to:
